Racial and ethnic disparities in influenza vaccination coverage among pregnant women in the United States: The contribution of vaccine-related attitudes. Prev Med 2023; 177:107751. [PMID: 37926397 PMCID: PMC10881081 DOI: 10.1016/j.ypmed.2023.107751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 10/30/2023] [Accepted: 10/31/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVE Racial and ethnic disparities in influenza vaccination coverage among pregnant women in the United States have been documented. This study assessed the contribution of vaccine-related attitudes to coverage disparities. METHODS Surveys were conducted following the 2019-2020 and 2020-2021 influenza seasons in a US research network. Using electronic health record data to identify pregnant women, random samples were selected for surveying; non-Hispanic Black women and influenza-unvaccinated women were oversampled. Regression-based decomposition analyses were used to assess the contribution of vaccine-related attitudes to racial and ethnic differences in influenza vaccination. Data were combined across survey years, and analyses were weighted and accounted for survey design. RESULTS Survey response rate was 41.2% (721 of 1748) for 2019-2020 and 39.3% (706 of 1798) for 2020-2021. Self-reported influenza vaccination was higher among non-Hispanic White respondents (79.4% coverage, 95% CI 73.1%-85.7%) than Hispanic (66.2% coverage, 95% CI 52.5%-79.9%) and non-Hispanic Black (55.8% coverage, 95% CI 50.2%-61.4%) respondents. For all racial and ethnic groups, a high proportion (generally >80%) reported being seen for care, recommended for influenza vaccination, and offered vaccination. In decomposition analyses, vaccine-related attitudes (e.g., worry about vaccination causing influenza; concern about vaccine safety and effectiveness) explained a statistically significant portion of the observed racial and ethnic disparities in vaccination. Maternal age, education, and health status were not significant contributors after controlling for vaccine-related attitudes. CONCLUSIONS In a setting with relatively high influenza vaccination coverage among pregnant women, racial and ethnic disparities in coverage were identified. Vaccine-related attitudes were associated with the disparities observed.

Abstract
Introduction Influenza remains a significant global public health challenge, causing substantial morbidity and mortality worldwide. Despite the availability of influenza vaccines, challenges related to vaccine hesitancy and healthcare professionals' attitudes persist. Furthermore, there is a need to understand the knowledge and opinions of undergraduate healthcare students regarding influenza vaccinations. Therefore, we aimed to assess and compare the knowledge and opinions of undergraduate healthcare students about influenza vaccinations, addressing the existing knowledge gap in this area. Methods We employed a cross-sectional study design to assess the opinions and knowledge of undergraduate healthcare students in Saudi Arabia regarding influenza vaccination. A total of 137 healthcare programs were invited to participate via filled-out the survey online. Data analysis was performed using SPSS, with descriptive statistics for the demographic profile and Chi-Square and independent t-tests for examining associations and differences in opinions and knowledge, respectively. Results A total of 429 undergraduate students completed the survey and were included. Significant associations were found between the students' major and their beliefs regarding the effectiveness of the vaccine in preventing influenza (p=0.017) and the inclusion of influenza vaccines in medical practice (p=0.016). The majority of students agreed with seven out of nine knowledge statements, with agreement percentages ranging from 42.9% to 44.8%. When comparing knowledge scores, students majoring in medicine had a significantly higher mean knowledge score (3.91) compared to students studying other medical sciences (3.72) (p=0.019). Conclusion and Recommendations Our study suggests that a comprehensive approach involving education, awareness initiatives, and policy changes is needed to enhance knowledge about influenza vaccination among Saudi Arabian undergraduate students in Medical School allied medical sciences and medical degree programs. By implementing these strategies, we can promote a positive attitude towards flu vaccination and ultimately increase its uptake.

Vaccines (Basel) 2023; 11:1231. [PMID: 37515046 PMCID: PMC10386611 DOI: 10.3390/vaccines11071231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 07/05/2023] [Accepted: 07/07/2023] [Indexed: 07/30/2023] Open
Abstract
To examine COVID-19 vaccination barriers in the US, this study drew on publicly available county-level data (n = 3130) to investigate the impact of vaccine hesitancy on the relationship between county-level social/structural barriers and vaccine coverage. A hierarchical regression was performed to establish the relationship between the COVID-19 Vaccine Coverage Index (CVAC) and vaccine coverage, assess the moderating effect of vaccine hesitancy on this relationship, and explore the influence of ethno-racial composition on vaccine coverage. A significant, negative relationship (r2 = 0.11, f2 = 0.12) between CVAC and vaccine coverage by county was established (step 1). When vaccine hesitancy was introduced as a moderator (step 2), the model significantly explained additional variance in vaccine coverage (r2 = 0.21, f2 = 0.27). Simple slopes analysis indicated a significant interaction effect, whereby the CVAC-vaccine coverage relationship was stronger in low hesitancy counties as compared with high hesitancy counties. Counties with low social/structural barriers (CVAC) but high hesitancy were projected to have 14% lower vaccine coverage. When county-level ethno-racial composition was introduced (step 3), higher proportions of white residents in a county predicted decreased vaccination rates (p < 0.05). Findings indicate that CVAC should be paired with vaccine hesitancy measures to better predict vaccine uptake. Moreover, counties with higher proportions of white residents led to decreases in vaccine uptake, suggesting that future intervention strategies should also target whites to reach herd immunity. We conclude that public health leaders and practitioners should address both social/structural and psychological barriers to vaccination to maximize vaccine coverage, with a particular focus on vaccine hesitancy in communities with minimal social/structural barriers.

Abstract
Influenza is a common respiratory infection associated with a substantial clinical, humanistic, and economic burden globally. Vaccines are essential to prevent and control influenza and are recommended by public-health agencies, such as the WHO and US CDC; however, vaccination rates vary considerably across the globe. This review aimed to investigate the perceived barriers and attitudes to influenza vaccination in the global population, in order to identify strategies that may improve influenza vaccination coverage. A structured literature search was undertaken to identify studies that reported on patient-reported attitudes towards influenza vaccination, focused on the adult general population in 16 prespecified countries. Eighty studies were included in this review. Negative attitude towards healthcare were found to be the most agreed upon barrier to vaccine uptake (31.1% agreement). The most agreed promoter of influenza vaccination was trust in healthcare services (62.0% agreement). Approximately 50% of participants intended to receive the influenza vaccine in the following season. To improve influenza vaccination coverage, healthcare workers must strengthen the foundation of substantial trust in healthcare services and provide educational materials that improve influenza vaccination knowledge among the adult general population.

Abstract
The Centers for Disease Control and Prevention recommends a COVID-19 vaccine booster dose for all persons >18 years of age. We analyzed data from the National Immunization Survey-Adult COVID Module collected during February 27-March 26, 2022 to assess COVID-19 booster dose vaccination coverage among adults. We used multivariable logistic regression analysis to assess factors associated with vaccination. COVID-19 booster dose coverage among fully vaccinated adults increased from 25.7% in November 2021 to 63.4% in March 2022. Coverage was lower among non-Hispanic Black (52.7%), and Hispanic (55.5%) than non-Hispanic White adults (67.7%). Coverage was 67.4% among essential healthcare personnel, 62.2% among adults who had a disability, and 69.9% among adults who had medical conditions. Booster dose coverage was not optimal, and disparities by race/ethnicity and other factors are apparent in coverage uptake. Tailored strategies are needed to educate the public and reduce disparities in COVID-19 vaccination coverage.

Abstract
Influenza vaccination is a critical preventive healthcare behavior designed to prevent spread of seasonal flu. This paper contributes to existing scholarship by applying an intersectional perspective to examine how influenza vaccination differs across specific intersections of racial/ethnic and sexual identity. Drawing on aggregated state-level data from Behavioral Risk Factor Surveillance System (BRFSS) from 2011 to 2020, I examine how flu vaccination differs across 18 racial/ethnic-by-sexual orientation groups (N = 1,986,432). Findings from descriptive analyses and logistic regression modeling demonstrate three key findings. First, it corroborates previous studies of vaccination, finding lower rates of flu vaccination among black adults relative to whites; gays/lesbians vaccinate at higher rates than heterosexuals and bisexuals, with bisexuals reporting lower vaccination relative to both heterosexuals and gays/lesbians. Second, it demonstrates how sexual orientation complicates established patterns between race/ethnicity and vaccination (e.g., influenza vaccination is more racially stratified among heterosexuals, with patterns more variable among gays/lesbians) and how race/ethnicity complicates previous patterns of vaccination by sexual orientation (e.g., Asian bisexuals vaccinate more than both heterosexuals). Third, findings pinpoint identities (e.g., black heterosexuals relative to their white peers and white bisexuals relative to their gay/lesbian peers) most in need of influenza vaccination outreach efforts. Implications for findings suggest that heterosexuals, especially black, may be less likely to vaccinate against influenza thus may need more encouragement from clinicians to vaccinate. Additionally, influenza vaccination should be free for all persons to lessen the barrier of access for this preventative healthcare.

Abstract
We assessed hepatitis A (HepA) vaccine receipt among susceptible individuals in outbreak and matched nonoutbreak states. Difference-in-differences models and multivariable logistic regression were used to compare HepA vaccination rates in these states. In the postoutbreak year, there was a 112% increase in HepA vaccinations in outbreak states versus a 6% decrease in nonoutbreak states. Differences persisted in our multivariable model (adjusted odds ratio = 2.53; 95% confidence interval = 2.45, 2.61). HepA vaccination rates increased dramatically in outbreak states, but many individuals susceptible to hepatitis A virus remain unvaccinated. (Am J Public Health.

Abstract
Background Adult vaccination coverage remains low in the United States, particularly among racial and ethnic minority populations. Objective To conduct a comprehensive literature review of research studies assessing racial and ethnic disparities in adult vaccination. Search Methods We conducted a search of PubMed, Cochrane Library, ClinicalTrials.gov, and reference lists of relevant articles. Selection Criteria Research studies were eligible for inclusion if they met the following criteria: (1) study based in the United States, (2) evaluated receipt of routine immunizations in adult populations, (3) used within-study comparison of race/ethnic groups, and (4) eligible for at least one author-defined PICO (patient, intervention, comparison, and outcome) question. Data Collection and Analysis Preliminary abstract review was conducted by two authors. Following complete abstraction of articles using a standardized template, abstraction notes and determinations were reviewed by all authors; disagreements regarding article inclusion/exclusion were resolved by majority rule. The Social Ecological Model framework was used to complete a narrative review of observational studies to summarize factors associated with disparities; a systematic review was used to evaluate eligible intervention studies. Results Ninety-five studies were included in the final analysis and summarized qualitatively within two main topic areas: (1) factors associated with documented racial-ethnic disparities in adult vaccination and (2) interventions aimed to reduce disparities or to improve vaccination coverage among racial-ethnic minority groups. Of the 12 included intervention studies, only 3 studies provided direct evidence and were of Level II, fair quality; the remaining 9 studies met the criteria for indirect evidence (Level I or II, fair or poor quality). Conclusions A considerable amount of observational research evaluating factors associated with racial and ethnic disparities in adult vaccination is available. However, intervention studies aimed at reducing these disparities are limited, are of poor quality, and insufficiently address known reasons for low vaccination uptake among racial and ethnic minority adults.

Poirier B, Sethi S, Garvey G, Hedges J, Canfell K, Smith M, Ju X, Jamieson L. HPV vaccine: uptake and understanding among global Indigenous communities - a qualitative systematic review. BMC Public Health 2021; 21:2062. [PMID: 34758805 PMCID: PMC8582096 DOI: 10.1186/s12889-021-12147-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 10/25/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Indigenous populations have a high prevalence of Human Papillomavirus (HPV) infection and a high incidence of HPV associated cancers, such as cervical and oropharyngeal cancer. There is an effective HPV vaccination program in almost all developed countries to prevent the incidence of cervical cancer, but reports suggest that the uptake of these vaccinations by Indigenous populations is low. The objective of this qualitative systematic review was to explore the knowledge and beliefs of global Indigenous populations regarding HPV vaccines. This review was performed to identify the barriers faced by Indigenous peoples and to provide evidence for more effective and acceptable execution of vaccination policies for Indigenous peoples. METHODS Two investigators independently searched MEDLINE, PubMed, SCOPUS, and Web of Science databases using a pre-specified search strategy to identify qualitative studies on narratives of Indigenous peoples regarding HPV vaccine awareness, knowledge and experiences across all geographic and income-level settings. RESULTS After performing the literature search and quality appraisals 5 papers were included in the final review. Three core synthesised findings were identified: reasons for acceptance or hesitancy, and areas for improvement. Lack of correct knowledge and mistrust in the healthcare system were important categories observed in all papers included in the review. Other categories within the conceptual model included prioritising disease prevention, health professional guidance, family support and supportive community environment. CONCLUSION Qualitative systematic reviews are an excellent means of exploring the gaps in current healthcare practices. Indigenous healthcare research should be grounded in community experiences and feedback. This review provides insights into HPV vaccination understanding and acceptance amongst Indigenous populations, from which recommendations for increasing resonance of vaccination strategies with Indigenous communities can be formed.

Abstract
INTRODUCTION Adults from racial and ethnic minorities and low-income groups are disproportionately affected by vaccine-preventable diseases. The objective of this study is to examine the trends in adult vaccination coverage in the U.S. by race/ethnicity and SES from 2010 to 2019. METHODS Temporal trends in influenza; pneumococcal; herpes zoster; and tetanus, diphtheria, and acellular pertussis vaccination coverage were examined by race/ethnicity and SES in 2020 using the National Health Interview Surveys from 2010 to 2019. RESULTS Influenza vaccination coverage differed by race/ethnicity among adults aged ≥65 years (61.4% for Black, 63.9% for Hispanic, 71.9% for Asian, and 72.4% for White adults). Race/ethnicity, household income, education level, and health insurance type were significantly associated with receipt of influenza; pneumococcal; tetanus, diphtheria, and acellular pertussis; and zoster vaccinations among adults aged ≥65 years in a multivariable-adjusted regression model. Socioeconomic differences in influenza vaccine uptake narrowed among adults aged 18-64 years from 2010 to 2019. By contrast, racial/ethnic and socioeconomic differences in vaccine uptake persisted from 2010 to 2019 among adults aged ≥65 years. CONCLUSIONS Racial and ethnic disparities in vaccine uptake persisted over the last decade. Socioeconomic disparities in influenza vaccine coverage narrowed among adults aged 18-64 years; however, disparities persisted among adults aged ≥65 years. Efforts are urgently needed to achieve equity in immunization rates.

Abstract
Vaccine hesitancy remains a global health threat. Addressing parental vaccine hesitancy is essential to maintaining high vaccine coverage levels and preventing disease outbreaks; however, it is unknown if administering a vaccine hesitancy screening tool negatively impacts parental vaccine beliefs. We conducted a stratified randomized controlled trial in pediatric primary care practices. English-speaking parents ≥18 years of age seeking routine care for infants <3 months of age were eligible. Participants were randomized to receive 1 of 2 surveys - the Parent Attitudes about Childhood Vaccines (PACV) survey or a placebo survey. Six months after initial enrollment, all participants were asked to complete the PACV, regardless of initial randomization group. Our primary outcome was the proportion of hesitant to non-hesitant parents at 6-months between randomization groups. We examined associations between vaccine hesitancy and participant characteristics. We also evaluated the change in the proportion of vaccine-hesitant parents in the PACV group between baseline and 6-month follow up. We enrolled 1705 parents at baseline. At 6-month follow up, 819 parents completed the PACV (50.2% from PACV group vs. 54.1% from placebo group). The proportion of hesitant parents at 6 months did not differ between PACV and placebo groups (6.6% vs. 6.1%; p = .78) and the odds of hesitancy among PACV group participants was not higher than those in the placebo group (OR = 1.10; 95% CI: 0.63-1.93; p = .743). Race was the only characteristic significantly associated with vaccine hesitancy at 6-month follow up (p = .003). Overall, administration of the PACV did not trigger vaccine hesitancy in this study population.

Abstract
A widely accepted severe acute respiratory syndrome 2 (SARS-CoV-2) vaccine could protect vulnerable populations, but the willingness of solid organ transplant recipients (SOTRs) to accept a potential vaccine remains unknown. METHODS We conducted a national survey of 1308 SOTRs and 1617 non-SOTRs between November 11 and December 2, 2020 through the network of the National Kidney Foundation. RESULTS Respondents were largely White (73.2%), female (61.1%), and college graduates (56.2%). Among SOTRs, half (49.5%) were unsure or would be unwilling to receive a SARS-CoV-2 vaccine once available. Major concerns included potential side effects (85.2%), lack of rigor in the testing and development process (69.7%), and fear of incompatibility with organ transplants (75.4%). Even after the announcement of the high efficacy of the mRNA-1273 vaccine (Moderna Inc.) at the time of survey distribution, likeliness to receive a vaccine only slightly increased (53.5% before announcement versus 57.8% after the announcement). However, 86.8% of SOTRs would accept a vaccine if recommended by a transplant provider. CONCLUSIONS SOTRs reported skepticism in receiving a potential SARS-CoV-2 vaccine, even after announcements of high vaccine efficacy. Reassuringly, transplant providers may be the defining influence in vaccine acceptance and will likely have a critical role to play in promoting vaccine adherence.

Public Health 2021; 195:76-82. [PMID: 34062275 DOI: 10.1016/j.puhe.2021.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 04/05/2021] [Accepted: 04/19/2021] [Indexed: 10/21/2022]
Abstract
STUDY DESIGN This is a Cross-sectional data analysis study. OBJECTIVES Our goal was to examine the association between internet use habits and influenza vaccination uptake using a nationally representative sample of non-institutionalised US adults. STUDY DESIGN This is a Cross-sectional data analysis study. METHODS We pooled data from seven years (2012-2018) of the National Health Interview Survey for secondary data analysis (N = 220,570). We estimated influenza vaccination uptake among different population groups. We performed multivariable logistic regression models with influenza vaccination uptake as a dichotomous dependent variable. RESULTS Influenza vaccination uptake was highest among those who used the internet for formal health information and communication with a provider (55.1%), and lowest among those internet users who did not use the internet for any type of formal or informal health information and communication (35.6%). About 45.2% of non-internet users received an influenza vaccination during the last 12 months. After controlling for covariates, compared with those who did not use the internet, adults who used the internet for formal health information and communication with providers were 1.52 times more likely to uptake an influenza vaccine (odds ratio [OR] = 1.52; 95% confidence interval [CI] = 1.45-1.59). Internet users who did not use the internet for any health information were significantly less likely to get vaccinated against influenza (OR = 0.92; 95% CI = 0.88-0.96). CONCLUSIONS It appears that internet use habit impacts influenza vaccination uptake. Internet users who do not use the internet for any formal or informal health information tend to have lower rates of influenza vaccine uptake than other groups. Customised interventions for different populations based on their internet use habits can help increase the national influenza vaccination rate and other immunisation efforts for contagious diseases.

Abstract
PROBLEM/CONDITION Adults are at risk for illness, hospitalization, disability and, in some cases, death from vaccine-preventable diseases, particularly influenza and pneumococcal disease. CDC recommends vaccinations for adults on the basis of age, health conditions, prior vaccinations, and other considerations. Updated vaccination recommendations from CDC are published annually in the U.S. Adult Immunization Schedule. Despite longstanding recommendations for use of many vaccines, vaccination coverage among U.S. adults remains low. REPORTING PERIOD August 2017-June 2018 (for influenza vaccination) and January-December 2018 (for pneumococcal, herpes zoster, tetanus and diphtheria [Td]/tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis [Tdap], hepatitis A, hepatitis B, and human papillomavirus [HPV] vaccination). DESCRIPTION OF SYSTEM The National Health Interview Survey (NHIS) is a continuous, cross-sectional national household survey of the noninstitutionalized U.S. civilian population. In-person interviews are conducted throughout the year in a probability sample of households, and NHIS data are compiled and released annually. NHIS's objective is to monitor the health of the U.S. population and provide estimates of health indicators, health care use and access, and health-related behaviors. Adult receipt of influenza, pneumococcal, herpes zoster, Td/Tdap, hepatitis A, hepatitis B, and at least 1 dose of HPV vaccines was assessed. Estimates were derived for a new composite adult vaccination quality measure and by selected demographic and access-to-care characteristics (e.g., age, race/ethnicity, indication for vaccination, travel history [travel to countries where hepatitis infections are endemic], health insurance status, contacts with physicians, nativity, and citizenship). Trends in adult vaccination were assessed during 2010-2018. RESULTS Coverage for the adult age-appropriate composite measure was low in all age groups. Racial and ethnic differences in coverage persisted for all vaccinations, with lower coverage for most vaccinations among non-White compared with non-Hispanic White adults. Linear trend tests indicated coverage increased from 2010 to 2018 for most vaccines in this report. Few adults aged ≥19 years had received all age-appropriate vaccines, including influenza vaccination, regardless of whether inclusion of Tdap (13.5%) or inclusion of any tetanus toxoid-containing vaccine (20.2%) receipt was measured. Coverage among adults for influenza vaccination during the 2017-18 season (46.1%) was similar to the estimate for the 2016-17 season (45.4%), and coverage for pneumococcal (adults aged ≥65 years [69.0%]), herpes zoster (adults aged ≥50 years and aged ≥60 years [24.1% and 34.5%, respectively]), tetanus (adults aged ≥19 years [62.9%]), Tdap (adults aged ≥19 years [31.2%]), hepatitis A (adults aged ≥19 years [11.9%]), and HPV (females aged 19-26 years [52.8%]) vaccination in 2018 were similar to the estimates for 2017. Hepatitis B vaccination coverage among adults aged ≥19 years and health care personnel (HCP) aged ≥19 years increased 4.2 and 6.7 percentage points to 30.0% and 67.2%, respectively, from 2017. HPV vaccination coverage among males aged 19-26 years increased 5.2 percentage points to 26.3% from the 2017 estimate. Overall, HPV vaccination coverage among females aged 19-26 years did not increase, but coverage among Hispanic females aged 19-26 years increased 10.8 percentage points to 49.6% from the 2017 estimate. Coverage for the following vaccines was lower among adults without health insurance compared with those with health insurance: influenza vaccine (among adults aged ≥19 years, 19-49 years, and 50-64 years), pneumococcal vaccine (among adults aged 19-64 years at increased risk), Td vaccine (among all age groups), Tdap vaccine (among adults aged ≥19 years and 19-64 years), hepatitis A vaccine (among adults aged ≥19 years overall and among travelers aged ≥19 years), hepatitis B vaccine (among adults aged ≥19 years and 19-49 years and among travelers aged ≥19 years), herpes zoster vaccine (among adults aged ≥60 years), and HPV vaccine (among males and females aged 19-26 years). Adults who reported having a usual place for health care generally reported receipt of recommended vaccinations more often than those who did not have such a place, regardless of whether they had health insurance. Vaccination coverage was higher among adults reporting ≥1 physician contact during the preceding year compared with those who had not visited a physician during the preceding year, regardless of whether they had health insurance. Even among adults who had health insurance and ≥10 physician contacts during the preceding year, depending on the vaccine, 20.1%-87.5% reported not having received vaccinations that were recommended either for all persons or for those with specific indications. Overall, vaccination coverage among U.S.-born adults was significantly higher than that of foreign-born adults, including influenza vaccination (aged ≥19 years), pneumococcal vaccination (all ages), tetanus vaccination (all ages), Tdap vaccination (all ages), hepatitis B vaccination (aged ≥19 years and 19-49 years and travelers aged ≥19 years), herpes zoster vaccination (all ages), and HPV vaccination among females aged 19-26 years. Vaccination coverage also varied by citizenship status and years living in the United States. INTERPRETATION NHIS data indicate that many adults remain unprotected against vaccine-preventable diseases. Coverage for the adult age-appropriate composite measures was low in all age groups. Individual adult vaccination coverage remained low as well, but modest gains occurred in vaccination coverage for hepatitis B (among adults aged ≥19 years and HCP aged ≥19 years), and HPV (among males aged 19-26 years and Hispanic females aged 19-26 years). Coverage for other vaccines and groups with Advisory Committee on Immunization Practices vaccination indications did not improve from 2017. Although HPV vaccination coverage among males aged 19-26 years and Hispanic females aged 19-26 years increased, approximately 50% of females aged 19-26 years and 70% of males aged 19-26 years remained unvaccinated. Racial/ethnic vaccination differences persisted for routinely recommended adult vaccines. Having health insurance coverage, having a usual place for health care, and having ≥1 physician contacts during the preceding 12 months were associated with higher vaccination coverage; however, these factors alone were not associated with optimal adult vaccination coverage, and findings indicate missed opportunities to vaccinate remained. PUBLIC HEALTH ACTIONS Substantial improvement in adult vaccination uptake is needed to reduce the burden of vaccine-preventable diseases. Following the Standards for Adult Immunization Practice (https://www.cdc.gov/vaccines/hcp/adults/for-practice/standards/index.html), all providers should routinely assess adults' vaccination status at every clinical encounter, strongly recommend appropriate vaccines, either offer needed vaccines or refer their patients to another provider who can administer the needed vaccines, and document vaccinations received by their patients in an immunization information system.

Abstract
Background Influenza health resource utilization studies are important to inform future public health policies and prevent outbreaks. This study aimed to describe influenza prevalence, vaccination, and treatment among outpatients in the United States and to evaluate population-level characteristics associated with influenza health resource utilization. Methods Data were extracted from the National Ambulatory and National Hospital Ambulatory Medical Care Surveys (2009 to 2016). Prevalence rates were described as influenza visits (defined by International Classification of Diseases, Ninth Revision, Clinical Modification or International Classification of Diseases, Tenth Revision code) per 1000 total visits overall and by flu year, month, region, race, and age group. Influenza vaccination and antiviral treatments were identified by Multum code(s) and presented as vaccination visits per 1000 total visits and the percentage of patients diagnosed with influenza receiving antiviral treatment. Results In more than 19.2 million patient visits, an influenza diagnosis was made with rates ranging from 1.2 per 1000 during 2014–2015 to 3.7 per 1000 during 2009–2010. Rates were highest in the South (3.6 per 1000), in December (5.2), among black patients (2.8), and those less than 18 years (6.8). Vaccination rates were highest during 2014–2015 (29.3 per 1000) and lowest during 2011–2012 (15.5 per 1000), in the West (23.4), in October (69.2), among “other race” patients (26.2), and age less than 18 years (51.4). Overall, 39.4% of patients with an influenza diagnosis received an antiviral. Conclusions Overall, there were no major changes in influenza diagnosis or vaccination rates. Patient populations with lower vaccination rates had higher influenza diagnosis rates. Future campaigns should promote influenza vaccinations particularly in underserved populations.

Abstract
Background Influenza vaccination among minoritized groups remains below federal benchmarks in the United States (US). We used data from the 2004–2016 California Health Interview Surveys (CHIS) to characterize influenza vaccination patterns among Arab Americans in California. Methods Influenza vaccination was self-reported by Arab American adults (N = 1163) and non-Hispanic Whites (NHW, N = 166,955). Differences in influenza vaccination prevalence and odds were compared using chi-squared tests and survey-weighted logistic regression, respectively. Results Across all years, 30.3% of Arab Americans self-reported receiving an influenza vaccine (vs. 40.5% for NHW, p < 0.05). After sequential adjustment by sociodemographic, health behavior, and acculturation variables no differences in odds of self-reported influenza vaccination were observed between Arab Americans and NHW (odds ratio: 1.02, 95% confidence interval: 0.76–1.38). Male and unemployed Arab Americans had higher odds of reporting influenza vaccination than female and employed Arab Americans. Conclusions Future work should consider specific barriers to influenza vaccination in Arab American communities.

Abstract
BACKGROUND Diabetes is associated with higher risk of hospitalization, morbidity, and mortality from influenza. We assessed influenza vaccination coverage among adults aged ≥ 18 years with diabetes during the 2007-08 through 2017-18 influenza seasons and identified factors independently associated with vaccination during the 2017-18 season. METHODS We analyzed data from the 2007-2018 National Health Interview Surveys, using Kaplan-Meier survival analysis to estimate season-specific influenza vaccination coverage. Multivariate logistic regression was conducted to examine whether diabetes was independently associated with self-reported influenza vaccination in the past 12 months and identify factors independently associated with vaccination among adults with diabetes using the 2017-18 data. RESULTS During the 2007-08 through 2017-18 influenza seasons, influenza vaccination coverage among adults aged ≥ 18 years with diabetes ranged from 62.6% to 64.8%. In the 2017-18 influenza season, coverage was significantly higher among adults with diabetes (64.8%) compared with those without diabetes (43.9%). Having diabetes was independently associated with an increased prevalence of vaccination after controlling for other factors. Among adults with diabetes, living at or above poverty level, having more physician contacts, having usual place for health care, and being unemployed were independently associated with increased prevalence of vaccination; being 18-64 years and non-Hispanic black were independently associated with decreased prevalence of vaccination. CONCLUSIONS Despite specific recommendations for influenza vaccination among people with diabetes, more than one-third of adults with diabetes are unvaccinated. Targeted efforts are needed to increase influenza vaccination coverage among adults with diabetes.

Am J Prev Med 2020; 59:21-31. [PMID: 32389533 PMCID: PMC9196997 DOI: 10.1016/j.amepre.2020.01.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 01/20/2020] [Accepted: 01/21/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION In 2006, zoster vaccine live was recommended for adults aged ≥60 years. In 2011, zoster vaccine live was approved for use but not recommended for adults aged 50-59 years. This study assessed zoster vaccine live coverage among adults aged 50-59 years and ≥60 years. METHODS Data from the 2013-2017 National Health Interview Surveys were analyzed in 2019 to estimate national zoster vaccine live coverage among adults aged ≥50 years. State-specific zoster vaccine live coverage among adults aged ≥50 years was assessed using 2017 Behavioral Risk Factor Surveillance System data. RESULTS Among adults aged 50-59 years, zoster vaccine live coverage was 5.7% in 2017, ranging from 4% to 6% during 2013-2017 (test for trend, p>0.05). Zoster vaccine live coverage among adults aged 50-59 years ranged from 5.8% in Pennsylvania to 14.7% in South Dakota. By 2017, zoster vaccine live was received by 34.9% of adults aged ≥60 years, a significant increase from 24.2% in 2013. Zoster vaccine live coverage among adults aged ≥60 years in 2017 ranged from 26.0% in Mississippi to 51.8% in Vermont. In 2017, major characteristics significantly associated with increased likelihood of zoster vaccine live vaccination among adults aged 50-59 years and ≥60 years were older age, having 4 to 9 physician contacts in the past 12 months, and having a usual place for health care. CONCLUSIONS This study provides an assessment of zoster vaccine live coverage among adults aged ≥50 years before the newly recommended recombinant zoster vaccine came into widespread use. Providers should routinely assess adults' vaccination status and strongly recommend or offer needed vaccines to their patients.

Abstract
While influenza vaccination in the prior year is a strong predictor of subsequent vaccination, many families do not have static vaccination patterns. This study examined factors guiding influenza vaccination decisions among parents whose children sporadically received the influenza vaccination (flu-floppers). We administered surveys to 141 flu-flopper families. Surveys included 21 factors associated with vaccine decision making. A conceptual framework of "passive" and "active" decision making was used to assess parental motivators behind vaccine decisions. The most common reason for vaccinating was a desire to prevent influenza (45%). The most common reason for not vaccinating was a belief that influenza vaccination is not effective (29%). Most parents (88%) reported an active reason in years when their child was vaccinated, while only 43% reported an active reason when their child was not vaccinated (P < .00001). These findings may guide efforts to increase influenza vaccination rates in children most amenable to vaccination.

Abstract
BACKGROUND Annual vaccination against seasonal influenza is widely recognized as the primary intervention method in preventing morbidity and mortality from influenza, but coverage among adults is suboptimal in the United States. Safety and effectiveness perceptions regarding vaccines are consistently cited as factors that influence adults' decisions to accept or reject vaccination. Therefore, we conducted this analysis in order to understand sociodemographic, attitude, and knowledge factors associated with these perceptions for influenza vaccine among adults in three different age groups. METHODS Probability-based Internet panel surveys using nationally representative samples of adults aged ≥19 years in the United States were conducted during February-March of 2017 and 2018. We asked respondents if they believed the influenza vaccine was safe and effective. We calculated prevalence ratios using chi-square and pairwise t-tests to determine associations between safety and effectiveness beliefs and sociodemographic variables for adults aged 19-49, 50-64, and ≥65 years. RESULTS Survey completion rates were 58.2% (2017) and 57.2% (2018); we analyzed 4597 combined responses. Overall, most adults reported the influenza vaccine was safe (86.3%) and effective (73.0%). However, fewer younger adults reported positive perceptions compared with older age groups. Respondents who believed the vaccine was safe also reported it was effective. CONCLUSIONS Generally, adults perceived the influenza vaccine as safe and effective. Considering this, any improvements to these perceptions would likely be minor and have a limited effect on coverage. Future research to understand why, despite positive perceptions, adults are still choosing to forego the vaccine may be informative.

Abstract
INTRODUCTION Influenza is a major cause of morbidity and mortality among adults. The most effective strategy for preventing influenza is annual vaccination. However, vaccination coverage has been suboptimal among adult populations. The purpose of this study is to assess trends in influenza vaccination among adult populations. METHODS Data from the 2010-2016 National Health Interview Survey were analyzed in 2018 to estimate vaccination coverage during the 2010-2011 through 2015-2016 seasons. Trends of vaccination in recent years were assessed. Vaccination coverage by race/ethnicity within each group was examined. Multivariable logistic regression and predictive marginal models were conducted to identify factors associated with vaccination, and interactions between race/ethnicity and other demographic and access-to-care characteristics were assessed. RESULTS Vaccination coverage among adults aged ≥18 years increased from 38.3% in the 2010-2011 season to 43.4% in the 2015-2016 season, with an average increase of 1.3 percentage points annually. From the 2010-2011 through 2015-2016 seasons, coverage was stable for adults aged ≥65 years and changed by -0.1 to 9.9 percentage points for all other examined subgroups. Coverage in 2015-2016 was 70.4% for adults aged ≥65 years, 46.4% for those aged 50-64 years, and 32.3% for those aged 18-49 years; 47.9% for people aged 18-64 years with high-risk conditions; 64.8% for healthcare personnel; and 50.3% for pregnant women. Among adults aged ≥18 years for the 2015-2016 season, coverage was significantly lower among non-Hispanic blacks and Hispanics compared with non-Hispanic whites. CONCLUSIONS Overall, influenza vaccination coverage among adults aged ≥18 years increased during 2010-2016, but it remained below the national target of 70%. Vaccination coverage varied by age, risk status, race/ethnicity, healthcare personnel, and pregnancy status. Targeted efforts are needed to improve coverage and reduce disparities.

Abstract
Extant work suggested pro-rich distribution of vaccination coverage in low- and middle-income countries (LMICs). However, the current literature also suggested pro-poor distribution of vaccination in some countries, including the Gambia, the Kyrgyz Republic and Namibia. This study aimed to explain socioeconomic inequalities in the completion rate of the four-core vaccines (i.e., Bacille Calmette-Guérin [BCG], diphtheria-tetanus-pertussis [DTP, 3 doses], Polio [3 doses] and Measles vaccines) in the three aforementioned countries. We used the most recent available Demographic Health Surveys (DHS) to measure vaccination completion rates among children (aged 0-59 months, n = 16,752) in the three countries. The normalized concentration index (Cn) was used to quantify and decompose socioeconomic inequalities in vaccination coverage in each country. The negative values of the Cn index suggested that children belong to lower socioeconomic status groups were more likely to be immunized than their higher socioeconomic status counterparts in the Gambia (Cn = -0.101, 95% confidence interval [CI]: -0.128 to -0.074), the Kyrgyz Republic (Cn = -0.097, 95% CI: -0.13 to -0.063) and Namibia (Cn = -0.161, 95% CI: -0.199 to -0.124). The decomposition analysis of the Cn suggested that the difference in child vaccination completion rates between rural and urban areas was the main factor contributing to the concentration of child vaccination among the poor in the Gambia and Namibia. The concentration of child vaccination among the poor in the Kyrgyz Republic was chiefly determined by household wealth. These results suggest that there should be strategies to improve child immunization uptake among urban children in the Gambia and Namibia. Since household wealth was the main factor contributing to the observed pro-poor distribution of child vaccination in the Kyrgyz Republic, further studies are required to understand the reasons for lower vaccination rate among the wealthy children in order to implement the most effective strategies to increase child vaccination uptake.

Abstract
OBJECTIVE To evaluate predictors of vaccination among women who received tetanus, diphtheria, and acellular pertussis vaccination (Tdap), influenza vaccination, and Tdap and influenza vaccinations. STUDY DESIGN In a retrospective cohort study of all full-term (≥37 weeks gestation) deliveries between July 1, 2016 and June 30, 2018 at a single, safety-net institution, we used multinomial logistic regression models to compare predictors of vaccination among women who received Tdap only, influenza only, and both Tdap and influenza vaccines. RESULTS Among 3132 full-term deliveries, women were primarily non-Hispanic black (67.5%), between the ages of 21-34 (65.3%), and multiparous (76.0%). The rates of only influenza or Tdap vaccination were 10.3% and 21.6%, respectively; 43.3% of women received both vaccines, and 24.9% of women did not receive either vaccine. In the adjusted models, Hispanic ethnicity was positively associated with receipt of all types of vaccination and non-Spanish language interpreter use was positively associated with receipt of Tdap vaccination and Tdap and influenza vaccination. A parity of greater than three and inadequate and unknown prenatal care adequacy were negative predictors of all types of vaccination. Pre-existing hypertension was negatively associated with Tdap vaccination, and HIV-positive status was negatively associated with influenza vaccination and Tdap and influenza vaccination. CONCLUSION Compared to the national rate of both Tdap and influenza vaccination (32.8%), a higher proportion of women received both vaccines in our study population. Vaccine uptake may be affected by race/ethnicity, use of interpreter services, parity, pre-existing comorbidities, and prenatal care adequacy. The lower rate of influenza vaccination compared to Tdap vaccination suggests that other factors, such as vaccine hesitancy and mistrust, may be differentially impacting influenza vaccination uptake in our predominantly minority population. Future provider and public health approaches to vaccine promotion should incorporate culturally appropriate strategies that address vaccine-related beliefs and misconceptions.

Abstract
Racial disparities in influenza vaccination persist between African American and White adults. It is critical to explore the reasons behind this disparity, which may be linked to the use of "folk" or home remedies for illness prevention and treatment. For this study, The GfK Group was contracted to conduct a nationally-representative survey (n = 819 African American and 838 White respondents). Respondents were asked about behaviors, attitudes, and risk perception related to the influenza vaccine, as well as frequency of home remedy use. Results were analyzed using adjusted logistic regression with 95% confidence intervals. In comparison to those who never use home remedies, those who use home remedies often or almost always were less likely to get vaccinated for influenza (respectively, OR = 0.70, CI 0.49, 0.99; OR = 0.27, CI 0.15, 0.49), less likely to be in favor of the vaccine (OR = 0.47, CI 0.33, 0.67; OR = 0.19, CI 0.10, 0.34), less likely to trust the vaccine (OR = 0.42, CI 0.29, 0.61; OR = 0.34, CI 0.20, 0.61), and more likely to perceive higher risk of vaccine side effects (OR = 1.79, CI 1.19, 2.68; OR = 4.00, CI 2.38, 6.73). These associations did not vary by race. Home remedy users may hold negative views toward the influenza vaccine, such that a combination of little trust in the vaccine process, and overestimation of risk associated with the vaccine itself, may contribute to vaccine refusal. Health care professionals can use these findings to tailor advice toward individuals with a preference for home remedy use to allay fears and correct misconceptions surrounding influenza and its vaccine.

Abstract
OBJECTIVE The recent Zika virus outbreak, while no longer an international public health emergency, is still a serious threat, particularly to pregnant women and babies born to pregnant women infected with the virus. This study examined the predictive effects of psychosocial constructs on self-reported intent to get a future Zika vaccine among women of reproductive age. METHODS Data were collected using an online survey with a representative sample of 339 women ages 18-49 from the continental United States. The survey addressed variables originating with the Extended Parallel Processing Model (EPPM) as related to future Zika vaccine uptake intent. RESULTS Three quarters of all respondents reported intention to get a future Zika vaccine. Path modeling revealed a direct effect of perceived susceptibility, self-efficacy, and response efficacy on future Zika vaccine uptake intent, as well as an indirect effect of perceived susceptibility through both self-efficacy and response efficacy. In addition, the final model showed an indirect effect of perceived severity on Zika vaccine uptake intent through self-efficacy and response efficacy and accounted for 54.6% of the variance in vaccination intent. CONCLUSIONS These findings have implications for future Zika vaccine promotion campaigns. This study confirms the importance of perceived susceptibility, self-efficacy, and response efficacy for use in Zika vaccine uptake campaigns; in addition, when using perceived severity, both self-efficacy and response efficacy should be considered in message design.

Abstract
Objectives The Advisory Committee on Immunization Practices (ACIP) and the American College of Obstetricians and Gynecologists (ACOG) recommend that pregnant women receive the Tdap vaccine during every pregnancy. The objectives of this paper are to evaluate disparities in Tdap vaccination among pregnant women in the U.S., and to assess whether race/ethnicity and other characteristics are associated with factors that inform pregnant women's decisions about Tdap vaccination. Methods We conducted a nationwide cross-sectional web-based survey of pregnant women in the U.S. during June-July 2014. The primary outcome was self-reported vaccination status with Tdap during pregnancy, categorized as vaccinated, unvaccinated with intent to be vaccinated during the current pregnancy, and unvaccinated with no intent to be vaccinated during the current pregnancy. Secondary outcomes included factors that influenced women's decisions about vaccination and information needs. We used multivariable logistic regression models to estimate odds ratios for associations between race/ethnicity and the outcomes. Results Among pregnant women who completed the survey, 41% (95% CI 36-45%) reported that they had received Tdap during the current pregnancy. Among those women in the third trimester at the time of survey, 52% (95% CI 43-60%) had received Tdap during the current pregnancy. Hispanic women had higher Tdap vaccination than white women and black women (53%, p < 0.05, compared with 38 and 36%, respectively). In logistic regression models adjusting for maternal age, geographic region, education, and income, Hispanic women were more likely to have been vaccinated with Tdap compared with white women (aOR 2.29, 95% CI 1.20-4.37). Higher income and residing in the western U.S. were also independently associated with Tdap vaccination during pregnancy. Twenty-six percent of surveyed women had not been vaccinated with Tdap yet but intended to receive the vaccine during the current pregnancy; this proportion did not differ significantly by race/ethnicity. The most common factor that influenced women to get vaccinated was a health care provider (HCP) recommendation. The most common reason for not getting vaccinated was a concern about safety of the vaccine. Conclusions This study found that some disparities exist in Tdap vaccination among pregnant women in the U.S., and HCPs have an important role in providing information and recommendations about the maternal Tdap recommendation to pregnant women so they can make informed vaccination decisions.

Abstract
INTRODUCTION Pregnant women are at increased risk for severe illness from influenza and influenza-related complications. Vaccinating pregnant women is the primary strategy to protect them and their infants from influenza. This study aims to assess influenza vaccination coverage during three influenza seasons (2012-2015) from a national probability-based sampling survey and evaluate potential factors that influence vaccination uptake among pregnant women. METHODS Data from the 2012 through 2015 National Health Interview Surveys were analyzed in 2017. Pregnant women aged 18-49 years were included in the analysis. The Kaplan-Meier survival analysis procedure was used for vaccination coverage in each season. Bivariate and multivariable logistic regression analyses were performed to examine factors associated with vaccination. Adjusted vaccination coverage and adjusted prevalence ratios are reported with corresponding 95% CIs. RESULTS In the 2012-2013, 2013-2014, and 2014-2015 influenza seasons, 40.4%, 45.4%, and 43.1% of pregnant women were vaccinated, respectively. Multivariable analysis indicated that factors independently associated with a lower likelihood of vaccination included having only a high school education, having three or less provider visits, and having no usual place of care (p<0.05). Less than half of women with ten or more visits were vaccinated (48.6%). CONCLUSIONS Vaccination coverage among pregnant women from this nationally representative sample was suboptimal during recent influenza seasons. Vaccination coverage was lower among certain sociodemographic, access-to-care subgroups. Multifactorial vaccination barriers may exist. Interventions, such as assessing vaccination history at every visit and implementing reminder-recall systems, standing orders, and addressing vaccination hesitancy, are needed to increase vaccination uptake among pregnant women.

Influenza Vaccination Coverage Among English-Speaking Asian Americans. Am J Prev Med 2018; 55:e123-e137. [PMID: 30262150 PMCID: PMC6402803 DOI: 10.1016/j.amepre.2018.06.018] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 03/16/2018] [Accepted: 06/15/2018] [Indexed: 11/23/2022]
Abstract
INTRODUCTION English-speaking non-Hispanic Asians (Asians) in the U.S. include populations with multiple geographic origins and ethnicities (e.g., Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese). Health behaviors and outcomes can differ widely among Asian ethnicities, and highlight the importance of subgroup analysis. Aggregating Asians may mask differences in influenza vaccination across various ethnicities. METHODS Combined data from 2013 to 2015 Behavioral Risk Factor Surveillance System, a population-based, telephone survey of the non-institutionalized, U.S. population aged ≥18years, were analyzed in 2017 to assess influenza vaccination among Asians. Weighted proportions were calculated. Multivariable logistic regression was used to determine independent associations between sociodemographic factors and receipt of influenza vaccination. RESULTS Influenza vaccination varied widely among Asian ethnicities, both nationally and by state. Overall, 42.1% of Asians reported having received an influenza vaccine, similar to vaccination among whites (42.4%). Coverage ranged from 36.1% among Koreans to 50.9% among Japanese. Factors independently associated with influenza vaccination among some or all Asian ethnicities included age (≥50 years), female, never married, high school or higher education, annual household income ≥$75,000, possession of medical insurance and personal healthcare provider, routine checkup in the previous year, and presence of certain chronic conditions. CONCLUSIONS Though Asians and whites had similar overall influenza vaccination coverage, differences existed between Asian ethnicities, both nationally and by state. This information may help community-based, state-level, and national-level public health agencies to support targeted approaches for outreach to these populations, such as improving cultural and linguistic access to care, to improve influenza vaccination.

Abstract
BACKGROUND Reminders for influenza vaccination improve influenza vaccination coverage. The purpose of this study was to describe the receipt of reminders for influenza vaccination during the 2011-12 influenza season among US adults. METHODS We analyzed data from the March 2012 National Flu Survey (NFS), a random digit dial telephone survey of adults in the United States. Relative to July 1, 2011, respondents were asked whether they received a reminder for influenza vaccination and the source and type of reminder they received. The association between reminder receipt and demographic variables, and the association between influenza vaccination coverage and receipt of reminders were also examined. RESULTS Of adults interviewed, 17.2% reported receiving a reminder since July 1, 2011. More than half (65.2%) of the reminders were sent by doctor offices. Hispanics and non-Hispanic blacks were more likely than non-Hispanic whites to report receiving a reminder. Adults who reported having a usual healthcare provider, health insurance, or a high-risk condition were more likely to report receiving reminders than the respective reference group. Adults reporting receipt of reminders were 1.15 times more likely (adjusted prevalence ratio, 95% CI: 1.06-1.25) to report being vaccinated for influenza than adults reporting not receiving reminders. CONCLUSIONS Differences exist in receipt of influenza vaccination reminders among adults. Reminders are important tools to improve adult influenza vaccination coverage. Greater use of reminders may lead to higher rates of adult influenza vaccination coverage and reductions in influenza-related morbidity.

Abstract
OBJECTIVE/STUDY QUESTION To examine racial/ethnic differences in influenza and pneumococcal vaccination receipt and nonreceipt among nursing home (NH) residents post implementation of federal vaccination policy. DATA SOURCES/STUDY SETTING/STUDY DESIGN/DATA COLLECTION/EXTRACTION METHODS: An analysis of a merged national cross-sectional dataset containing resident assessment, facility, and community data for years 2010-2013 was conducted. Logistic regressions omitting and including facility fixed effects were used to examine the influence of race and ethnicity (black, Hispanic, white) and black concentration on vaccination status across and within NHs. PRINCIPLE FINDINGS Vaccination receipt of 107,874 residents in 742 NHs was examined. Blacks were less likely than whites to receive influenza and pneumococcal vaccinations (OR = 0.75; OR = 0.81, respectively, p-values <.001). The likelihood of not being offered the influenza vaccination was greater for blacks (OR=1.25, p = .004) and the likelihood of not being offered the pneumococcal vaccination was greater for Hispanics (OR = 1.65, p = .04) compared to whites. Fixed effects showed that within the same NH, Hispanics were more likely to receive both vaccinations compared to whites (OR=1.22, p = .004 (influenza); OR=1.34, p < .001 (pneumococcal)). Facilities highly concentrated with blacks accounted for large proportions of differences seen in vaccination receipt. CONCLUSIONS Racial/ethnic differences remain despite policy changes. Focused strategies aimed at NH personnel and racially segregated NHs are critical to improving vaccination delivery and eliminating disparities in care.

Abstract
BACKGROUND The effectiveness of interventions to increase influenza vaccination uptake in people aged 60 years and older varies by country and participant characteristics. This review updates versions published in 2010 and 2014. OBJECTIVES To assess access, provider, system, and societal interventions to increase the uptake of influenza vaccination in people aged 60 years and older in the community. SEARCH METHODS We searched CENTRAL, which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE, Embase, CINAHL, and ERIC for this update, as well as WHO ICTRP and ClinicalTrials.gov for ongoing studies to 7 December 2017. We also searched the reference lists of included studies. SELECTION CRITERIA Randomised controlled trials (RCTs) and cluster-randomised trials of interventions to increase influenza vaccination in people aged 60 years or older in the community. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as specified by Cochrane. MAIN RESULTS We included three new RCTs for this update (total 61 RCTs; 1,055,337 participants). Trials involved people aged 60 years and older living in the community in high-income countries. Heterogeneity limited some meta-analyses. We assessed studies as at low risk of bias for randomisation (38%), allocation concealment (11%), blinding (44%), and selective reporting (100%). Half (51%) had missing data. We assessed the evidence as low-quality. We identified three levels of intervention intensity: low (e.g. postcards), medium (e.g. personalised phone calls), and high (e.g. home visits, facilitators).Increasing community demand (12 strategies, 41 trials, 53 study arms, 767,460 participants)One successful intervention that could be meta-analysed was client reminders or recalls by letter plus leaflet or postcard compared to reminder (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.15; 3 studies; 64,200 participants). Successful interventions tested by single studies were patient outreach by retired teachers (OR 3.33, 95% CI 1.79 to 6.22); invitations by clinic receptionists (OR 2.72, 95% CI 1.55 to 4.76); nurses or pharmacists educating and nurses vaccinating patients (OR 152.95, 95% CI 9.39 to 2490.67); medical students counselling patients (OR 1.62, 95% CI 1.11 to 2.35); and multiple recall questionnaires (OR 1.13, 95% CI 1.03 to 1.24).Some interventions could not be meta-analysed due to significant heterogeneity: 17 studies tested simple reminders (11 with 95% CI entirely above unity); 16 tested personalised reminders (12 with 95% CI entirely above unity); two investigated customised compared to form letters (both 95% CI above unity); and four studies examined the impact of health risk appraisals (all had 95% CI above unity). One study of a lottery for free groceries was not effective.Enhancing vaccination access (6 strategies, 8 trials, 10 arms, 9353 participants)We meta-analysed results from two studies of home visits (OR 1.30, 95% CI 1.05 to 1.61) and two studies that tested free vaccine compared to patient payment for vaccine (OR 2.36, 95% CI 1.98 to 2.82). We were unable to conduct meta-analyses of two studies of home visits by nurses plus a physician care plan (both with 95% CI above unity) and two studies of free vaccine compared to no intervention (both with 95% CI above unity). One study of group visits (OR 27.2, 95% CI 1.60 to 463.3) was effective, and one study of home visits compared to safety interventions was not.Provider- or system-based interventions (11 strategies, 15 trials, 17 arms, 278,524 participants)One successful intervention that could be meta-analysed focused on payments to physicians (OR 2.22, 95% CI 1.77 to 2.77). Successful interventions tested by individual studies were: reminding physicians to vaccinate all patients (OR 2.47, 95% CI 1.53 to 3.99); posters in clinics presenting vaccination rates and encouraging competition between doctors (OR 2.03, 95% CI 1.86 to 2.22); and chart reviews and benchmarking to the rates achieved by the top 10% of physicians (OR 3.43, 95% CI 2.37 to 4.97).We were unable to meta-analyse four studies that looked at physician reminders (three studies with 95% CI above unity) and three studies of facilitator encouragement of vaccination (two studies with 95% CI above unity). Interventions that were not effective were: comparing letters on discharge from hospital to letters to general practitioners; posters plus postcards versus posters alone; educational reminders, academic detailing, and peer comparisons compared to mailed educational materials; educational outreach plus feedback to teams versus written feedback; and an intervention to increase staff vaccination rates.Interventions at the societal levelNo studies reported on societal-level interventions.Study funding sourcesStudies were funded by government health organisations (n = 33), foundations (n = 9), organisations that provided healthcare services in the studies (n = 3), and a pharmaceutical company offering free vaccines (n = 1). Fifteen studies did not report study funding sources. AUTHORS' CONCLUSIONS We identified interventions that demonstrated significant positive effects of low (postcards), medium (personalised phone calls), and high (home visits, facilitators) intensity that increase community demand for vaccination, enhance access, and improve provider/system response. The overall GRADE assessment of the evidence was moderate quality. Conclusions are unchanged from the 2014 review.

Abstract
Background: Infants younger than 6 months of age are at high risk for contracting pertussis because of not being fully vaccinated. The Advisory Committee on Immunization Practices (ACIP) recommends vaccinating all pregnant women with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) between 27 and 36 weeks to offer passive immunity to the infant to help protect them until they are able to receive the full pertussis series. Objective: To assess and compare compliance with the 2013 ACIP recommendation of vaccinating pregnant women with Tdap at 27 to 36 weeks’ gestation in 2 obstetric clinics. Methods: This cross-sectional, retrospective chart review evaluated Tdap vaccine compliance in a random sample of obstetric patients from October 2013 to September 2014. The primary outcome evaluated the proportion of patients who received Tdap between 27 and 36 weeks’ gestation. Secondary outcomes included the proportion of patients who received Tdap at any point in pregnancy and within 30 days postpartum. Results: The charts of 573 patients were reviewed, and 237 met inclusion criteria. For the primary outcome, 142 patients (59.9%) received the Tdap vaccine. Overall, 156 patients (65.8%) received Tdap at some point during the pregnancy. Factors associated with receiving the Tdap vaccination were insurance status, prenatal care risk level and site of prenatal care, receipt of the influenza vaccine, and preterm labor in the current pregnancy. Conclusion: The Tdap vaccine rate was 65.8%, with 59.9% of patients receiving the vaccine within the recommended ACIP timeframe. Further education, improvements in documentation, and chart reminders are needed to enhance administration.

Abstract
INTRODUCTION Outbreaks of pertussis can occur in healthcare settings. Vaccinating healthcare personnel may be helpful in protecting healthcare personnel from pertussis and potentially limiting spread to others in healthcare settings. METHODS Data from 21 states using the 2013 Behavioral Risk Factor Surveillance System industry/occupation module were analyzed in 2016. Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination status was self-reported by healthcare personnel along with their occupation, healthcare setting/industry, demographics, and access to care factors. To compare groups, t-tests were used. The median state response rate was 44.0%. RESULTS Among all healthcare personnel, 47.2% were vaccinated for Tdap. Physicians had higher Tdap coverage (66.8%) compared with all other healthcare personnel except nurse practitioners and registered nurses (59.5%), whose coverage did not statistically differ from that of physicians. Tdap vaccination coverage was higher among workers in hospitals (53.3%) than in long-term care facilities (33.3%) and other clinical settings, such as dentist, chiropractor, and optometrist offices (39.3%). Healthcare personnel who were younger, who had higher education, higher annual household income, a personal healthcare provider, and health insurance had higher Tdap vaccination coverage compared with reference groups. Tdap vaccination coverage among healthcare personnel in 21 states ranged from 30.6% in Mississippi to 65.9% in Washington. CONCLUSIONS Improvement in Tdap vaccination among healthcare personnel is needed to potentially reduce opportunities for spread of pertussis in healthcare settings. On-site workplace vaccination, offering vaccines free of charge, and promoting vaccination may increase vaccination among healthcare personnel.

Abstract
Black adults are significantly less likely to be immunized for seasonal influenza when compared to Whites. This persistent disparity contributes to increased influenza-related morbidity and mortality in the African American population. Most scholarship on vaccine disparities has compared Whites and Blacks. Employing Public Health Critical Race Praxis, this study seeks to shift the focus to explore differences within the Black population. Utilizing a nationally-representative 2015 survey of US Black adults (n = 806), we explore differences by gender, age, income, and education across vaccine-related measures (e.g., perceived risk, knowledge, attitudes) and racial factors (e.g. racial salience, racial fairness, perceived discrimination). We also explore differences by vaccine behavior in the past five years among those who vaccinate every year, most years but not all, once or twice, and never. Greater frequency of flu vaccine uptake was associated with better self-reported vaccine knowledge, more positive vaccine attitudes, more trust in the flu vaccine and the vaccine process, higher perceived disease risk, lower perceived risk of vaccine side effects, stronger subjective and moral norms, lower general vaccine hesitancy, higher confidence in the flu vaccine, and lower perceived barriers. Logistic regression results highlighted other significant differences among the groups, emphasizing areas to target for improved vaccination rates. We find great diversity within the Black community related to influenza immunization decisions, highlighting the need to “break down the monolith” in future research. Empirically tested differences within the Black population for flu vaccine behavior. Detected significant differences in past vaccine behavior by age, gender, income, and education. Focus on past behavior to move adults along the continuum to increase vaccination. Highlights diversity within the Black population, often missing from comparative studies.

Abstract
Pregnant women and their infants are at increased risk for severe influenza-associated illness (1), and since 2004, the Advisory Committee on Immunization Practices (ACIP) has recommended influenza vaccination for all women who are or might be pregnant during the influenza season, regardless of the trimester of the pregnancy (2). To assess influenza vaccination coverage among pregnant women during the 2016-17 influenza season, CDC analyzed data from an Internet panel survey conducted during March 28-April 7, 2017. Among 1,893 survey respondents pregnant at any time during October 2016-January 2017, 53.6% reported having received influenza vaccination before (16.2%) or during (37.4%) pregnancy, similar to coverage during the preceding four influenza seasons. Also similar to the preceding influenza season, 67.3% of women reported receiving a provider offer for influenza vaccination, 11.9% reported receiving a recommendation but no offer, and 20.7% reported receiving no recommendation; among these women, reported influenza vaccination coverage was 70.5%, 43.7%, and 14.8%, respectively. Among women who received a provider offer for vaccination, vaccination coverage differed by race/ethnicity, education, insurance type, and other sociodemographic factors. Use of evidence-based practices such as provider reminders and standing orders could reduce missed opportunities for vaccination and increase vaccination coverage among pregnant women.

Cancer Med 2017; 6:2153-2163. [PMID: 28776947 PMCID: PMC5603841 DOI: 10.1002/cam4.1141] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 06/11/2017] [Accepted: 06/15/2017] [Indexed: 11/25/2022] Open
Abstract
To assess differences in the receipt of preventive health services by race/ethnicity among older women with endometrial cancer enrolled in Medicare, we conducted a retrospective population-based cohort study of women diagnosed with endometrial cancer from 2001 to 2011 in the Surveillance Epidemiology and End Results (SEER)-Medicare database. Women with stage I or II endometrial cancer of epithelial origin were included. The exposure was race/ethnicity (Non-Hispanic [NH] White, NH Black, Hispanic, and NH Asian/Pacific Islander [PI]). The services examined were receipt of influenza vaccination and screening tests for diabetes mellitus, hyperlipidemia, and breast cancer. We used multivariate logistic regression to estimate odds ratios with 95% confidence intervals (CI) adjusted for age, region, and year of diagnosis. A total of 13,054 women were included. In the 2 years after diagnosis, receipt of any influenza vaccine ranged from 45% among NH Black women to 67% among NH White women; receipt of a mammogram ranged from 65% among NH Black women to 74% among NH White women. Relative to NH White women, NH Black women had a lower likelihood of receiving both influenza vaccination (adjusted odds ratio [aOR] 0.40, 95% CI 0.33-0.44) and screening mammography (aOR 0.64, 95% CI 0.52-0.79). Hispanic women also were less likely to receive influenza vaccination than NH White women (aOR 0.61, 95% CI 0.51-0.72). There were no significant differences across racial groups for diabetes or cholesterol screening services. Among older women with early-stage endometrial cancer, racial disparities exist in the utilization of some preventive services.

Black CL, Williams WW, Arbeloa I, Kordic N, Yang L, MaCurdy T, Worrall C, Kelman JA. Trends in Influenza and Pneumococcal Vaccination Among US Nursing Home Residents, 2006-2014. J Am Med Dir Assoc 2017; 18:735.e1-735.e14. [PMID: 28623156 PMCID: PMC5751715 DOI: 10.1016/j.jamda.2017.05.002] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2016] [Revised: 04/29/2017] [Accepted: 05/02/2017] [Indexed: 01/05/2023]
Abstract
BACKGROUND Institutionalized adults are at increased risk of morbidity and mortality from influenza and pneumococcal infection. Influenza and pneumococcal vaccination have been shown to be effective in reducing hospitalization and deaths due to pneumonia and influenza in this population. OBJECTIVE To assess trends in influenza vaccination coverage among US nursing home residents from the 2005-2006 through 2014-2015 influenza seasons and trends in pneumococcal vaccination coverage from 2006 to 2014 among US nursing home residents, by state and demographic characteristics. METHODS Data were analyzed from the Centers for Medicare and Medicaid Services' (CMS's) Minimum Data Set (MDS). Influenza and pneumococcal vaccination status were assessed for all residents of CMS-certified nursing homes using data reported to the MDS by all certified facilities. RESULTS Influenza vaccination coverage increased from 71.4% in the 2005-2006 influenza season to 75.7% in the 2014-2015 influenza season and pneumococcal vaccination coverage increased from 67.4% in 2006 to 78.4% in 2014. Vaccination coverage varied by state, with influenza vaccination coverage ranging from 50.0% to 89.7% in the 2014-2015 influenza season and pneumococcal vaccination coverage ranging from 55.0% to 89.7% in 2014. Non-Hispanic black and Hispanic residents had lower coverage compared with non-Hispanic white residents for both vaccines, and these differences persisted over time. CONCLUSION Influenza and pneumococcal vaccination among US nursing home residents remains suboptimal. Nursing home staff can employ strategies such as provider reminders and standing orders to facilitate offering vaccination to all residents along with culturally appropriate vaccine promotion to increase vaccination coverage among this vulnerable population.

Abstract
PROBLEM/CONDITION Overall, the prevalence of illness attributable to vaccine-preventable diseases is greater among adults than among children. Adults are recommended to receive vaccinations based on their age, underlying medical conditions, lifestyle, prior vaccinations, and other considerations. Updated vaccination recommendations from CDC are published annually in the U.S. Adult Immunization Schedule. Despite longstanding recommendations for use of many vaccines, vaccination coverage among U.S. adults is low. PERIOD COVERED August 2014-June 2015 (for influenza vaccination) and January-December 2015 (for pneumococcal, tetanus and diphtheria [Td] and tetanus and diphtheria with acellular pertussis [Tdap], hepatitis A, hepatitis B, herpes zoster, and human papillomavirus [HPV] vaccination). DESCRIPTION OF SYSTEM The National Health Interview Survey (NHIS) is a continuous, cross-sectional national household survey of the noninstitutionalized U.S. civilian population. In-person interviews are conducted throughout the year in a probability sample of households, and NHIS data are compiled and released annually. The survey objective is to monitor the health of the U.S. population and provide estimates of health indicators, health care use and access, and health-related behaviors. RESULTS Compared with data from the 2014 NHIS, increases in vaccination coverage occurred for influenza vaccine among adults aged ≥19 years (a 1.6 percentage point increase compared with the 2013-14 season to 44.8%), pneumococcal vaccine among adults aged 19-64 years at increased risk for pneumococcal disease (a 2.8 percentage point increase to 23.0%), Tdap vaccine among adults aged ≥19 years and adults aged 19-64 years (a 3.1 percentage point and 3.3 percentage point increase to 23.1% and to 24.7%, respectively), herpes zoster vaccine among adults aged ≥60 years and adults aged ≥65 years (a 2.7 percentage point and 3.2 percentage point increase to 30.6% and to 34.2%, respectively), and hepatitis B vaccine among health care personnel (HCP) aged ≥19 years (a 4.1 percentage point increase to 64.7%). Herpes zoster vaccination coverage in 2015 met the Healthy People 2020 target of 30%. Aside from these modest improvements, vaccination coverage among adults in 2015 was similar to estimates from 2014. Racial/ethnic differences in coverage persisted for all seven vaccines, with higher coverage generally for whites compared with most other groups. Adults without health insurance reported receipt of influenza vaccine (all age groups), pneumococcal vaccine (adults aged 19-64 years at increased risk), Td vaccine (adults aged ≥19 years, 19-64 years, and 50-64 years), Tdap vaccine (adults aged ≥19 years and 19-64 years), hepatitis A vaccine (adults aged ≥19 years overall and among travelers), hepatitis B vaccine (adults aged ≥19 years, 19-49 years, and among travelers), herpes zoster vaccine (adults aged ≥60 years), and HPV vaccine (males and females aged 19-26 years) less often than those with health insurance. Adults who reported having a usual place for health care generally reported receipt of recommended vaccinations more often than those who did not have such a place, regardless of whether they had health insurance. Vaccination coverage was higher among adults reporting one or more physician contacts in the past year compared with those who had not visited a physician in the past year, regardless of whether they had health insurance. Even among adults who had health insurance and ≥10 physician contacts within the past year, depending on the vaccine, 18.2%-85.6% reported not having received vaccinations that were recommended either for all persons or for those with specific indications. Overall, vaccination coverage among U.S.-born adults was higher than that among foreign-born adults, with few exceptions (influenza vaccination [adults aged 19-49 years and 50-64 years], hepatitis A vaccination [adults aged ≥19 years], and hepatitis B vaccination [adults aged ≥19 years with diabetes or chronic liver conditions]). INTERPRETATION Coverage for all vaccines for adults remained low but modest gains occurred in vaccination coverage for influenza (adults aged ≥19 years), pneumococcal (adults aged 19-64 years with increased risk), Tdap (adults aged ≥19 years and adults aged 19-64 years), herpes zoster (adults aged ≥60 years and ≥65 years), and hepatitis B (HCP aged ≥19 years); coverage for other vaccines and groups with vaccination indications did not improve. The 30% Healthy People 2020 target for herpes zoster vaccination was met. Racial/ethnic disparities persisted for routinely recommended adult vaccines. Missed opportunities to vaccinate remained. Although having health insurance coverage and a usual place for health care were associated with higher vaccination coverage, these factors alone were not associated with optimal adult vaccination coverage. HPV vaccination coverage for males and females has increased since CDC recommended vaccination to prevent cancers caused by HPV, but many adolescents and young adults remained unvaccinated. PUBLIC HEALTH ACTIONS Assessing factors associated with low coverage rates and disparities in vaccination is important for implementing strategies to improve vaccination coverage. Evidence-based practices that have been demonstrated to improve vaccination coverage should be used. These practices include assessment of patients' vaccination indications by health care providers and routine recommendation and offer of needed vaccines to adults, implementation of reminder-recall systems, use of standing-order programs for vaccination, and assessment of practice-level vaccination rates with feedback to staff members. For vaccination coverage to be improved among those who reported lower coverage rates of recommended adult vaccines, efforts also are needed to identify adults who do not have a regular provider or insurance and who report fewer health care visits.

Abstract
BACKGROUND Influenza illnesses can result in missed days at work and societal costs, but influenza vaccination can reduce the risk of disease. Knowledge of vaccination coverage by industry and occupation can help guide prevention efforts and be useful during influenza pandemic planning. METHODS Data from 21 states using the 2013 Behavioral Risk Factor Surveillance System industry-occupation module were analyzed. Influenza vaccination coverage was reported by select industry and occupation groups, including health care personnel (HCP) and other occupational groups who may have first priority to receive influenza vaccination during a pandemic (tier 1). The t tests were used to make comparisons between groups. RESULTS Influenza vaccination coverage varied by industry and occupation, with high coverage among persons in health care industries and occupations. Approximately half of persons classified as tier 1 received influenza vaccination, and vaccination coverage among tier 1 and HCP groups varied widely by state. CONCLUSIONS This report points to the particular industries and occupations where improvement in influenza vaccination coverage is needed. Prior to a pandemic event, more specificity on occupational codes to define exact industries and occupations in each tier group would be beneficial in implementing pandemic influenza vaccination programs and monitoring the success of these programs.

Abstract
BACKGROUND Provider recommendations and offers for influenza vaccination improve adult influenza vaccination coverage. Analysis was performed to describe receipt of influenza vaccination recommendations and offers among adults who visited a healthcare provider (HCP) during the 2011-2012 influenza season and describe differences between those receiving and not receiving recommendations and offers for influenza vaccination. Associations between influenza vaccination and receipt of recommendations and offers were examined. METHODS Respondents to a random digit dial telephone survey who had visited a HCP since July 1, 2011 were asked if they had received a recommendation for influenza vaccination. Those receiving a recommendation were asked if they received an offer for vaccination. Participants were characterized by demographic and access to health care variables. Logistic regression was used to examine the relationships between participant characteristics and recommendation alone, between participant characteristics and recommendation and offer, and between influenza vaccination and recommendation and offer. RESULTS Of those who reported visiting a HCP, 43.8% reported receiving a recommendation for influenza vaccination. Of those who reported receiving a recommendation, 76.6% reported receiving an offer for influenza vaccination. Persons with high-risk conditions and persons over 65 years were more likely to receive recommendations for influenza vaccination when compared to those without high-risk conditions and 18-49 year olds, respectively. Those reporting receipt of a recommendation and offer for influenza vaccination were 1.76 times more likely and those reporting receipt of a recommendation but no offer were 1.72 times more likely to report being vaccinated for influenza controlling for all patient characteristics. CONCLUSIONS Less than half of respondents reported receipt of recommendations and offers of influenza vaccination during the 2011-2012 influenza season and disparities exist between groups. All healthcare providers seeing adults should recommend or offer influenza vaccination for all patients at every visit during the influenza season.

Exploring racial influences on flu vaccine attitudes and behavior: Results of a national survey of White and African American adults. Vaccine 2017; 35:1167-1174. [PMID: 28126202 DOI: 10.1016/j.vaccine.2016.12.046] [Citation(s) in RCA: 138] [Impact Index Per Article: 19.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2016] [Revised: 12/15/2016] [Accepted: 12/16/2016] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Racial disparities in adult flu vaccination rates persist with African Americans falling below Whites in vaccine acceptance. Although the literature has examined traditional variables including barriers, access, attitudes, among others, there has been virtually no examination of the extent to which racial factors including racial consciousness, fairness, and discrimination may affect vaccine attitudes and behaviors. METHODS We contracted with GfK to conduct an online, nationally representative survey with 819 African American and 838 White respondents. Measures included risk perception, trust, vaccine attitudes, hesitancy and confidence, novel measures on racial factors, and vaccine behavior. RESULTS There were significant racial differences in vaccine attitudes, risk perception, trust, hesitancy and confidence. For both groups, racial fairness had stronger direct effects on the vaccine-related variables with more positive coefficients associated with more positive vaccine attitudes. Racial consciousness in a health care setting emerged as a more powerful influence on attitudes and beliefs, particularly for African Americans, with higher scores on racial consciousness associated with lower trust in the vaccine and the vaccine process, higher perceived vaccine risk, less knowledge of flu vaccine, greater vaccine hesitancy, and less confidence in the flu vaccine. The effect of racial fairness on vaccine behavior was mediated by trust in the flu vaccine for African Americans only (i.e., higher racial fairness increased trust in the vaccine process and thus the probability of getting a flu vaccine). The effect of racial consciousness and discrimination for African Americans on vaccine uptake was mediated by perceived vaccine risk and flu vaccine knowledge. CONCLUSIONS Racial factors can be a useful new tool for understanding and addressing attitudes toward the flu vaccine and actual vaccine behavior. These new concepts can facilitate more effective tailored and targeted vaccine communications.

Abstract
BACKGROUND People living with chronic health conditions exhibit higher risk for developing severe complications from influenza according to the Centers for Diseases Control and Prevention. Although racial and ethnic disparities in influenza vaccination have been documented, it has not been comprehensively determined whether similar disparities are present among the adult population with at least one such condition. OBJECTIVE To study if racial and ethnic disparities in relation to influenza vaccination are present in adults suffering from at least one chronic condition and if such inequalities differ between age groups. METHODS The Medical Expenditure Panel Survey (2011-2012) was used to study the adult population (age ≥18) who had at least one chronic health condition. Baseline differences in population traits across racial and ethnic groups were identified using a chi-square test. This was conducted among various age groups. In addition, survey logistic regression was utilized to produce odds ratios of receiving influenza vaccination annually between racial and ethnic groups. RESULTS The total sample consisted of 15,499 adults living with at least one chronic health condition. The numbers of non-Hispanic whites (whites), non-Hispanic blacks (blacks), and Hispanics were 8,658, 3,585, and 3,256, respectively. Whites (59.93%) were found to have a higher likelihood of self-reporting their receipt of the influenza vaccine in comparison to the black (48.54%) and Hispanic (48.65%) groups (P<0.001). When examining persons aged 50-64 years and ≥65 years, it was noted that the black (54.99%, 62.72%) and Hispanic (53.54%, 64.48%) population had lower rates of influenza vaccine coverage than the white population (59.22%, 77.89) (both P<0.0001). No significant differences between whites and the blacks or Hispanics were found among the groups among adults between 18 and 49 inclusive (P>0.05). After controlling for patient characteristics, the difference in influenza vaccine coverage between whites and the minority groups were no longer significant for adults aged 50-64 years. However, the difference were still statistically significant for those aged ≥65 years. CONCLUSIONS In the United States, there are significant disparities in influenza vaccination by race and ethnicity for adults over 65 years with at least one chronic health condition. Future research is needed to help develop more targeted interventions to address these issues and improve influenza vaccination rates.

Abstract
Patients at a high-risk of severe influenza, because of their underlying health disorders, are recommended to receive a seasonal influenza vaccination. In Poland, influenza coverage rate in the general population is very low (3.4 %). However, there is little known about the coverage rate among high-risk patients. The aim of this study was to describe a general knowledge, perception, and influenza vaccination coverage rate among Polish patients with enhanced risk for influenza. We conducted a self-reported survey among 500 patients with chronic disorders: 120 pulmonary, 80 hemodialyzed, 100 thyroid cancer, and 200 cardiovascular patients. We found the following influenza vaccination coverage in the respective groups of patients: 58 % in pulmonary, 34 % in hemodialyzed, 32 % in cardiovascular, and 9 % in thyroid cancer patients. The difference between the coverage rate in pulmonary patients compared with the other risk groups was significant (p < 0.05). In pulmonary patients, the most important barrier for influenza vaccination was a lack of recommendations from healthcare workers, while a high awareness of influenza was the most powerful driver for vaccination (p < 0.05). We conclude that although the influenza vaccination coverage in Polish patients with chronic diseases is higher than that reported in the general population, this rate remains much below the recommended level and should be improved.

Abstract
OBJECTIVE The annual outbreak of influenza is one of the major causes of morbidity and mortality among the elderly population around the world. While there is an annual vaccine available to prevent or reduce the incidence of disease, not all older people in Korea choose to be vaccinated. There have been few previous studies to examine the factors influencing influenza vaccination in Korea. Thus, this study identifies nationwide factors that affect influenza vaccination rates in elderly Koreans. METHODS We obtained data from the Fourth Korean National Health and Nutrition Examination Survey 2007-2009 (KNHANES IV), a nationwide health survey in Korea. To assess influenza vaccination status, we analysed answers to a single question from the survey. From the respondents, we selected 3567 elderly population aged 65 years or older, to analyse the effects of variables including sociodemographic, health behavioural risk, health status and psychological factors on vaccination coverage. We identified factors that affect vaccination status using a multiple logistic regression analysis. RESULTS The rate of influenza vaccination in this elderly population was 75.8%. Overall, the most significant determinants for choosing influenza vaccination were a recent history of health screening (adjusted OR (aOR) 2.26, 95% CI 1.92 to 2.66) and smoking (aOR 0.78, 95% CI 0.62 to 0.98). Other contributing factors were age, household income, marital status, alcohol consumption, physical activity level, self-reported health status and a limitation in daily activities. In contrast, psychological factors, including self-perceived quality of life, stress and depressive mood, did not show close association with vaccination coverage. CONCLUSIONS To boost influenza vaccination rates in the elderly, an influenza campaign should focus on under-represented groups, especially smokers. Additionally, promoting routine health screening for the elderly may be an efficient way to help achieve higher vaccination rates. Our results highlight the need for a new strategy for the vaccination campaign.

Abstract
INTRODUCTION Reducing racial/ethnic disparities in immunization rates is a compelling public health goal. Disparities in childhood vaccination rates have not been observed in recent years for most vaccines. The objective of this study is to assess adult vaccination by race/ethnicity in the U.S. METHODS The 2012 National Health Interview Survey was analyzed in 2014 to assess adult vaccination by race/ethnicity for five vaccines routinely recommended for adults: influenza, tetanus, pneumococcal (two vaccines), human papilloma virus, and zoster vaccines. Multivariable logistic regression analysis was performed to identify factors independently associated with all adult vaccinations. RESULTS Vaccination coverage was significantly lower among non-Hispanic blacks, Hispanics, and non-Hispanic Asians compared with non-Hispanic whites, with only a few exceptions. Age, sex, education, health insurance, usual place of care, number of physician visits in the past 12 months, and health insurance were independently associated with receipt of most of the examined vaccines. Racial/ethnic differences narrowed, but gaps remained after taking these factors into account. CONCLUSIONS Racial and ethnic differences in vaccination levels narrow when adjusting for socioeconomic factors analyzed in this survey, but are not eliminated, suggesting that other factors that are associated with vaccination disparities are not measured by the National Health Interview Survey and could also contribute to the differences in coverage. Additional efforts, including systems changes to ensure routine assessment and recommendations for needed vaccinations among adults for all racial/ethnic groups, are essential for improving vaccine coverage.

Abstract
Introduction The goal of the study was to identify perceived barriers to implementation of vaccination services encountered by independent and small-chain community pharmacies in an urban setting. Methods Pharmacists in independent and small-chain pharmacies located in 29 Michigan ZIP codes were visited and asked to complete a 5- to 10-min semi-structured interview. Results A total of 93 independent and 12 small-chain pharmacies participated (n = 105; 61%). The pharmacies filled an average of 700 prescriptions each week with 1.1 pharmacist full-time equivalents and 57 h of technician time. The most common services that participating pharmacies provided were dispensing outpatient medication (99%), medication therapy management (MTM, 65.7%), disease management or coaching (54.3%), point-of-care testing (34.3%), and dispensing medications to inpatient facilities (16.2%). Only seven pharmacies (6.7%) administered vaccinations. When pharmacists were asked to identify what it would take to start to administer vaccines, the most common responses were increased demand from patients (37.1%), adequate time (19%), appropriate space (17.1%), appropriate amount of staff (14.3%), change in attitudes or beliefs of the owner or pharmacists at that pharmacy (13.3%), increased profit related to vaccines (11.4%), and increased awareness among patients about the importance of vaccines (11.4%). The majority of pharmacies (65.3%) reported that only one factor would need to change to start to administer vaccines. Conclusion Independent and small-chain community pharmacies in an urban, primarily low-income area identified several barriers that have prevented implementation of vaccination services. However, the majority of pharmacies reported that only one factor would need to change in order to begin to administer vaccines. Interventional efforts necessary to address commonly cited barriers may include providing education to pharmacists about the need for community pharmacy-based immunization programs in addition to services provided by physician offices, as well as the importance of proactively providing immunization-related recommendations to patients.

Am J Infect Control 2016; 44:1004-9. [PMID: 27372226 DOI: 10.1016/j.ajic.2016.03.064] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2016] [Revised: 03/02/2016] [Accepted: 03/02/2016] [Indexed: 11/18/2022]
Abstract
BACKGROUND The Advisory Committee on Immunization Practices recommends annual flu vaccination for all adults. We aimed to identify predictors of receiving a flu vaccination, with an emphasis on the impact of race and ethnicity. METHODS We used data from the 2011-2012 California Health Interview Survey and included all individuals aged ≥18 years. We performed a survey-weighted logistic regression on receipt of flu vaccination within the last year, adjusted by demographic and socioeconomic variables, and calculated odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Our study included a population-weighted sample of 27,796,484 individuals. Overall, 35.8% received a flu vaccination within the last year. Blacks were 33% less likely (95% CI, 21%-43%) to have been vaccinated than whites. Conversely, Koreans (OR, 1.77; 95% CI, 1.35-2.33) and Vietnamese (OR, 1.57; 95% CI, 1.19-2.07) were more likely than whites to have been vaccinated. No differences were seen between whites and the remaining racial and ethnic groups (Latino, Japanese, Chinese, Filipino, South Asian, Asian other, and other). CONCLUSIONS Racial and ethnic disparities in flu vaccination uptake exist in California. Namely, blacks have lower vaccination rates than whites, and there are disparate vaccination rates among the Asian-American subgroups. Efforts to increase vaccination rates among these groups are needed.

Abstract
This paper studies consumer learning in influenza vaccination decisions. We examine consumer learning in influenza vaccine demand within a reduced form instrumental variable framework that exploits differences in risk characteristics of different influenza viruses as a natural experiment to distinguish the effects of learning based on previous influenza vaccination experiences from unobserved heterogeneity. The emergence of a new virus strain (influenza A H1N1/09) during the 2009 'Swine flu' pandemic resulted in two different vaccines being recommended for distinct population subgroups with some people, who were not usually targeted by seasonal vaccination programs, being specifically recommended for the new Swine flu vaccine. We use these differences in vaccination targeting to construct instrumental variables for estimating the effect of past influenza vaccination experiences on the demand for pandemic vaccine. We find large causal effects of previous seasonal vaccination on pandemic vaccination. Causal effects of past influenza vaccination experiences on perceived vaccination safety are likely to be an important pathway linking past vaccination experiences with future vaccine uptake. Our results suggest a significant role of learning in vaccination decisions. Current efforts to expand seasonal vaccination may thus have potentially important long-term effects on future influenza vaccination levels and pandemic preparedness.
