[PMID: 38704255 DOI: 10.1016/j.vaccine.2024.04.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 02/13/2024] [Accepted: 04/09/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Globally, cardiovascular disease (CVD) is the leading cause of death and illness. Vaccine-preventable infections may increase acute coronary vascular disease events and the risk of complications. Low vaccine coverage has been reported among adults at high risk of complications from vaccine-preventable infections. There is a gap in research evidence around determinants of uptake of vaccines among adults with CVD. This study examined the uptake of influenza, pneumococcal and zoster vaccines and the determinants of uptake of the vaccines among cardiac patients. METHOD A prospective cross-sectional study was carried out among hospitalised cardiac patients through an interviewer-administered questionnaire. Descriptive statistics were used to investigate self-reported uptake of influenza, pneumococcal and zoster vaccines. Univariate and multivariate analyses of participants' social demographic and clinical characteristics were conducted to identify factors for receiving influenza vaccine. RESULTS Low vaccination rates among 104 participants were found for influenza (45.2%), pneumococcal (13.5%) and zoster (5.8%) vaccines. The most common reason for not receiving influenza vaccine was concern about side effects. Lack of awareness about the pneumococcal and zoster vaccines was the main reason for the poor uptake of these vaccines. Australia-born participants were more likely to receive influenza vaccine than overseas-born participants. Working-age participants and, interestingly, people living with a current smoker were less likely to receive influenza vaccine. CONCLUSION Influenza, pneumococcal and zoster vaccine uptake among cardiac patients was low. Encouraging physician recommendations for vaccination for cardiac patients under 65 years of age and addressing vaccination challenges among people from culturally and linguistically diverse backgrounds and pharmacy, workplace, and hospital vaccination may help increase vaccination uptake among cardiac patients.

Front Public Health 2024; 12:1360556. [PMID: 38706547 PMCID: PMC11066301 DOI: 10.3389/fpubh.2024.1360556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/09/2024] [Indexed: 05/07/2024] Open
Abstract
Background Diabetes affects millions of people worldwide, making them more vulnerable to infections, including seasonal influenza. It is therefore particularly important for those suffering from diabetes to be vaccinated against influenza each year. However, influenza vaccination coverage remains low in this population. This review primarily aims to identify the determinants of influenza vaccination in people with diabetes (T1D or T2D). Secondly, it aims to assess main recommendations for influenza vaccination, vaccine effectiveness, vaccination coverage, and how education and pharmacists can encourage uptake of the vaccine in the diabetic population. Methods A scoping review was conducted in January 2022 to systematically review evidence on influenza vaccination in people with diabetes using data from PubMed, Science Direct, and EM Premium with terms such as "Diabetes mellitus," "Immunization Programs," "Vaccination," and "Influenza Vaccines." Quality assessment and data extraction were independently conducted by two authors. Disagreements between the authors were resolved through discussion and consensus, and if necessary, by consulting a third author. Results Of the 333 records identified, 55 studies met the eligibility criteria for inclusion in this review. Influenza vaccination was recommended for people ≥6 months. Despite effectiveness evidence showing a reduction in mortality and hospitalizations in people with diabetes vaccinated vs. non-vaccinated ones, very few studies reported a coverage rate ≥ 75%, which is WHO's target objective. Determinants such as advanced age, presence of comorbidities and healthcare givers' advice were associated with increased vaccination uptake. On the contrary, fear of adverse reactions and concerns about vaccine effectiveness were significant barriers. Finally, education and pharmacists' intervention played a key role in promoting vaccination and increasing vaccination uptake. Conclusion Influenza vaccination coverage in people with diabetes remains low despite recommendations and evidence on vaccine effectiveness. Motivators and barriers as well as several socio-demographic and clinical factors have been identified to explain this trend. Efforts are now needed to increase the number of diabetics vaccinated against influenza, mainly through education and the involvement of healthcare givers.

Abstract
BACKGROUND Influenza vaccination is recommended and provided free-of-charge to Danish citizens aged ≥65 years and to individuals with acquired immunodeficiency. We aimed to estimate influenza vaccination coverage and investigate predictors of influenza non-vaccination in Danish cancer patients. METHODS A nationwide cohort study of all Danish citizens aged ≥18 years with an incident cancer diagnosis between 2002 and 2017. Using national registries, we assessed information on influenza vaccination and potential predictors of influenza non-vaccination. We estimated adjusted prevalence ratios (aPR) of influenza non-vaccination for patients aged <65 years and ≥65 years. RESULTS We observed 269,863 patients during 840,876 influenza vaccination seasons. The influenza vaccination coverage was 14 % for cancer patients <65 years and 51 % for those ≥65 years. No influenza vaccination in the previous season was associated with non-vaccination in the current season (<65 years: aPR = 2.75, 95 %CI = 2.71-2.80; ≥65 years: aPR = 5.15, 95 %CI = 5.10-5.21). Haematological cancer patients receiving chemotherapy had lower vaccination prevalence compared with those not receiving chemotherapy. CONCLUSIONS The influenza vaccination coverage was low among cancer patients. Influenza non-vaccination in the previous season was the strongest predictor of not receiving influenza vaccination in the current season. Haematological cancer patients on current chemotherapy had lower vaccination prevalence than those not currently receiving chemotherapy.

Vaccines (Basel) 2023; 11:1712. [PMID: 38006044 PMCID: PMC10675465 DOI: 10.3390/vaccines11111712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/28/2023] [Accepted: 11/03/2023] [Indexed: 11/26/2023] Open
Abstract
Seasonal influenza is a leading cause of death in the U.S., causing significant morbidity, mortality, and economic burden. Despite the proven efficacy of vaccinations, rates remain notably low, especially among Medicaid enrollees. Leveraging Medicaid claims data, this study characterizes influenza vaccination rates among Medicaid enrollees and aims to elucidate factors influencing vaccine uptake, providing insights that might also be applicable to other vaccine-preventable diseases, including COVID-19. This study used Medicaid claims data from nine U.S. states (2016-2021], encompassing three types of claims: fee-for-service, major Medicaid managed care plan, and combined. We included Medicaid enrollees who had an in-person healthcare encounter during an influenza season in this period, excluding those under 6 months of age, over 65 years, or having telehealth-only encounters. Vaccination was the primary outcome, with secondary outcomes involving in-person healthcare encounters. Chi-square tests, multivariable logistic regression, and Fisher's exact test were utilized for statistical analysis. A total of 20,868,910 enrollees with at least one healthcare encounter in at least one influenza season were included in the study population between 2016 and 2021. Overall, 15% (N = 3,050,471) of enrollees received an influenza vaccine between 2016 and 2021. During peri-COVID periods, there was an increase in vaccination rates among enrollees compared to pre-COVID periods, from 14% to 16%. Children had the highest influenza vaccination rates among all age groups at 29%, whereas only 17% were of 5-17 years, and 10% were of the 18-64 years were vaccinated. We observed differences in the likelihood of receiving the influenza vaccine among enrollees based on their health conditions and medical encounters. In a study of Medicaid enrollees across nine states, 15% received an influenza vaccine from July 2016 to June 2021. Vaccination rates rose annually, peaking during peri-COVID seasons. The highest uptake was among children (6 months-4 years), and the lowest was in adults (18-64 years). Female gender, urban residency, and Medicaid-managed care affiliation positively influenced uptake. However, mental health and substance abuse disorders decreased the likelihood. This study, reliant on Medicaid claims data, underscores the need for outreach services.

Prevalence of influenza-specific vaccination hesitancy among adults in the United States, 2018. Vaccine 2023; 41:2572-2581. [PMID: 36907734 PMCID: PMC10941755 DOI: 10.1016/j.vaccine.2023.03.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 01/17/2023] [Accepted: 03/05/2023] [Indexed: 03/12/2023]
Abstract
BACKGROUND The role of vaccine hesitancy on influenza vaccination is not clearly understood. Low influenza vaccination coverage in U.S. adults suggests that a multitude of factors may be responsible for under-vaccination or non-vaccination including vaccine hesitancy. Understanding the role of influenza vaccination hesitancy is important for targeted messaging and intervention to increase influenza vaccine confidence and uptake. The objective of this study was to quantify the prevalence of adult influenza vaccination hesitancy (IVH) and examine association of IVH beliefs with sociodemographic factors and early-season influenza vaccination. METHODS A four-question validated IVH module was included in the 2018 National Internet Flu Survey. Weighted proportions and multivariable logistic regression models were used to identify correlates of IVH beliefs. RESULTS Overall, 36.9% of adults were hesitant to receive an influenza vaccination; 18.6% expressed concerns about vaccination side effects; 14.8% personally knew someone with serious side effects; and 35.6% reported that their healthcare provider was not the most trusted source of information about influenza vaccinations. Influenza vaccination ranged from 15.3 to 45.2 percentage points lower among adults self-reporting any of the four IVH beliefs. Being female, age 18-49 years, non-Hispanic Black, having high school or lower education, being employed, and not having primary care medical home were associated with hesitancy. CONCLUSIONS Among the four IVH beliefs studied, being hesitant to receiving influenza vaccination followed by mistrust of healthcare providers were identified as the most influential hesitancy beliefs. Two in five adults in the United States were hesitant to receive an influenza vaccination, and hesitancy was negatively associated with vaccination. This information may assist with targeted interventions, personalized to the individual, to reduce hesitancy and thus improve influenza vaccination acceptance.

Uptake of influenza, pneumococcal and herpes zoster vaccines among people with heart failure and atrial fibrillation. Vaccine 2022; 40:7709-7713. [PMID: 36379753 DOI: 10.1016/j.vaccine.2022.10.090] [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: 04/10/2022] [Revised: 10/30/2022] [Accepted: 10/31/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Cardiovascular diseases are the major cause of hospitalisation and death globally. Infections exacerbate cardiovascular events among cardiac patients, contributing to all-cause mortality. Vaccination is a cheap and effective intervention that can prevent infection. In Australia, influenza, pneumococcal and herpes zoster vaccines are recommended and funded for high-risk adults such as cardiac patients. There is high prevalence of high-risk adults in Western Sydney. OBJECTIVES This study investigates the uptake of influenza, pneumococcal and herpes zoster vaccines in patients admitted with heart failure and atrial fibrillation in a tertiary hospital in Western Sydney and factors associated with the uptake of the vaccines. METHODS Consecutive patients' hospitalised between 2014 and 2018 with heart failure or atrial fibrillation as principal diagnoses were identified. Information on patients' social demographic, clinical and vaccination status was collected and described using descriptive analysis. Univariate and multivariate analyses were conducted to determine factors associated with the uptake of the vaccines. RESULTS Low uptake for pneumococcal (40-45 %) and herpes zoster (15 %) vaccines were found. Prevalence of influenza vaccination was lower among participants younger than 65 (51-72 %) than in older ones (78-96 %). Australia-born participants were more likely to receive pneumococcal vaccine than those born overseas (OR 2.02, 95 % CI 1.05-3.89). Participants 65 years or older and those with comorbidities such as hypertension, COPD and chronic renal impairment were more likely to receive the vaccines. CONCLUSION Multidisciplinary strategies are needed to improve access to vaccination, community knowledge, community engagement, and healthcare provider support to provide appropriate care to migrants and younger cardiac patients and reduce morbidity and mortality in this high-risk group.

Abstract
Elderly individuals with chronic illnesses are more prone to get influenza. We aimed to investigate the factors associated with influenza coverage and willingness in chronic disease patients aged ≥60 years in Longhua district, Shenzhen City of southern China. Data collected in October 2020 were used in this work. The immunization status of older persons with chronic conditions and their willingness to receive the vaccine were assessed. Multivariable logistic regression was employed to determine the respective independent factors related to vaccination coverage and willingness for influenza. Only 4.8% of 5045 people were immunized against influenza, whereas 92.7% of the individuals agreed to receive the vaccine. Individuals between the ages of 70 and 79 (adjusted OR [aOR] 1.47, P = .012), those with higher education levels (aOR 1.53, P = .005 for high school; aOR 2.44, P < .001 for college or above), those who use of a family doctor (aOR 2.91, P < .001), those who frequently have physical examinations once a year (aOR 2.52, P < .001), and those who have never smoked (aOR 1.62, P = .018) were positively associated with the influenza vaccination. Meanwhile, older age was adversely linked with influenza vaccination willingness (aOR 0.68 for 70-79 years, P = .003; aOR 0.55 for≥80 years, P = .025) in contrast to those aged 60-69. High willingness to get vaccinated was more frequent in people with a high school diploma (aOR 1.33, P = .037). In this work, we observed that the coverage is poor but the immunization desire is high regarding influenza vaccination. Interestingly, older age was associated with higher coverage and lower willingness. These suggest that raising immunization rates among older people with chronic conditions and strengthening health education for caregivers should be the primary concerns.

Abstract
Life-course immunization holds significant benefit for population health by reducing the burden of vaccine-preventable diseases (VPD) through vaccinating individuals at different stages and circumstances in life. The study aimed to determine the epidemiologic, clinical, economic, and societal burden of VPDs among at-risk adult subpopulations in the United States. A systematic literature review was conducted for articles published between January 2010 and June 2020, which identified 72 publications. There was heterogeneity in available epidemiology data, with the prevalence of VPDs ranging from 1.1% to 68.7%. Where the disease burden was described, outcomes were typically worse among high-risk subpopulations than in the general population. Several VPDs, including herpes zoster, meningococcal, and pneumococcal infections were associated with increased costs. This review suggests that subpopulations may not frequently interact with the healthcare system, or their risk factors may not be recognized by healthcare providers, and therefore individuals may not be appropriately targeted for vaccination.

Abstract
To reduce morbidity and mortality associated with vaccine-preventable diseases (VPD), it is imperative that vaccination programs are implemented and prioritized throughout all stages of life across all populations. This study aimed to determine vaccine uptake and barriers to vaccination against VPDs among at-risk adult populations in the United States. We conducted a systematic literature review for articles published between January 2010 and June 2020 and identified 153 publications. The review identified 17 at-risk populations. Vaccine uptake was suboptimal among many populations, with factors including age, gender, and disease severity, associated with uptake. This review identified several barriers that impact vaccine uptake among at-risk populations, with concerns over safety, vaccine costs, lack of insurance, and lack of provider recommendation commonly reported across populations. Embracing a national life-course immunization framework that integrates developing policies, guidelines, and education would be a step to addressing these barriers.

Abstract
BACKGROUND AND AIMS Influenza is an acute respiratory disease with the highest mortality rate in the high-risk groups. Vaccination is a key public health strategy to prevent influenza in high-risk people. This study aimed to assess the influenza vaccination coverage rate and identify its demographic determinants in patients with end-stage renal disease (ESRD), chronic obstructive pulmonary disease (COPD), and diabetes in Birjand, Eastern Iran. METHODS This cross-sectional study included 400 patients (300 diabetic, 60 dialysis, and 40 COPD patients) from September 2017 to August 2018. Using interview method, we completed a questionnaire containing the patients' demographic characteristics, questions about patients' knowledge and attitude toward influenza vaccination, the influenza vaccination history, and the most common causes for vaccination. The relationship between the type of disease and patients' characteristics (exposure) with vaccination coverage (outcome) was investigated. RESULTS The mean age of participants was 58.7 ± 11.3 years. Also, 58.8% of the patients received at least one dose of the vaccine and the regular injection rate was 32.8%. The coverage of influenza vaccine in dialysis patients was significantly higher than other patients (p < 0.001). The mean knowledge score was 6.17 ± 2.15 out of maximum 9 scores. There was a positive association between age [p = 0.001, odds ratio (OR) = 1.04] and patients' knowledge (p < 0.001, OR = 1.42) with the vaccination coverage. CONCLUSION The coverage of influenza vaccine in high-risk patients in Birjand was low. Hence, it is essential to increase the knowledge of high-risk groups about the importance of influenza vaccination and facilitate their access to vaccines.

COVID-19 Vaccination and Intent for Vaccination of Adults With Reported Medical Conditions. Am J Prev Med 2022; 63:760-771. [PMID: 35864015 PMCID: PMC9234053 DOI: 10.1016/j.amepre.2022.05.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 05/07/2022] [Accepted: 05/31/2022] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Individuals with certain medical conditions are at substantially increased risk for severe illness from COVID-19. The purpose of this study is to assess COVID-19 vaccination among U.S. adults with reported medical conditions. METHODS Data from the National Immunization Survey-Adult COVID Module collected during August 1-September 25, 2021 were analyzed in 2022 to assess COVID-19 vaccination status, intent, vaccine confidence, behavior, and experience among adults with reported medical conditions. Unadjusted and age-adjusted prevalence ratios (PRs and APRs) were generated using logistic regression and predictive marginals. RESULTS Overall, COVID-19 vaccination coverage with ≥1 dose was 81.8% among adults with reported medical conditions, and coverage was significantly higher compared with those without such conditions (70.3%) Among adults aged ≥18 years with medical conditions, COVID-19 vaccination coverage was significantly higher among those with a provider recommendation (86.5%) than those without (76.5%). Among all respondents, 9.2% of unvaccinated adults with medical conditions reported they were willing or open to vaccination. Adults who reported high risk medical conditions were more likely to report receiving a provider recommendation, often or always wearing masks during the last 7 days, concerning about getting COVID-19, thinking the vaccine is safe, and believing a COVID-19 vaccine is important for protection from COVID-19 infection than those without such conditions. CONCLUSIONS Approximately 18.0% of those with reported medical conditions were unvaccinated. Receiving a provider recommendation was significantly associated with vaccination, reinforcing that provider recommendation is an important approach to increase vaccination coverage. Ensuring access to vaccine, addressing vaccination barriers, and increasing vaccine confidence can improve vaccination coverage among unvaccinated adults.

Impact of Hospitalization in an Endocrinology Department on Vaccination Coverage in People Living with Diabetes: A Real-Life Study. Medicina (B Aires) 2022; 58:medicina58020219. [PMID: 35208544 PMCID: PMC8879927 DOI: 10.3390/medicina58020219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 01/17/2022] [Accepted: 01/27/2022] [Indexed: 12/04/2022] Open
Abstract
Background and Objectives: Vaccination coverage is suboptimal in people living with diabetes. The objectives of this study were to determine the impact of hospitalization on vaccination coverage and the variables associated with vaccination during hospital stay. Materials and Methods: This observational study was conducted from May 2019 to December 2019 in the Endocrinology-Nutrition-Diabetes Department of the University Hospital of Montpellier, France. This department encompasses three medical units, two of which have a full-time clinical pharmacist involved in the multidisciplinary management of patients. All adult diabetic patients who completed a questionnaire about vaccines were prospectively included by a clinical pharmacist and followed until department discharge. Coverage at the time of admission for the tetanus, diphtheria, pertussis (Tdap), pneumococcal, influenza, and herpes zoster vaccines was assessed from patient interviews and/or contact with the general practitioner and/or with the community pharmacist. Multivariable logistic regression analysis was performed to identify the factors associated with a vaccination update during the hospital stay. Results: A total of 222 patients were included (mean age: 59.4 years, 68.5% type 2 diabetes). Vaccination coverage increased by 26.7% (47.3% to 59.9%), 188.0% (10.8% to 31.1%) and 8.9% (45.9% to 50.0%), respectively, for the Tdap, pneumococcal and influenza vaccines during hospital stay. Female sex, admission to a diabetes care unit with a full-time pharmacist, favorable feelings about vaccination, unknown immunization coverage for pneumococcal vaccines, and evaluation and recording of vaccine coverage at admission in the patient medical records were associated with at least one vaccination during hospital stay. Conclusions: Our real-life study highlights that hospitalization and multidisciplinary management (i.e., physician-pharmacist) may be key points in the diabetes care pathway to improve vaccination coverage, especially for patients with advanced diabetes and comorbidities.

Abstract
Researchers strive to design and implement high-quality surveys to maximize the utility of the data collected. The definitions of quality and usefulness, however, vary from survey to survey and depend on the analytic needs. Survey teams must evaluate the trade-offs of various decisions, such as when results are needed and their required level of precision, in addition to practical constraints like budget, before finalizing the design. Characteristics within the concept of fit for purpose (FfP) can provide the framework for considering the trade-offs. Furthermore, this tool can enable an evaluation of quality for the resulting estimates. Implementation of a FfP framework in this context, however, is not straightforward. In this article, we provide the reader with a glimpse of a FfP framework in action for obtaining estimates on early season influenza vaccination coverage estimates and on knowledge, attitudes, behaviors, and barriers related to influenza and influenza prevention among civilian noninstitutionalized adults aged 18 years and older in the United States. The result is the National Internet Flu Survey (NIFS), an annual, two-week internet survey sponsored by the US Centers for Disease Control and Prevention. In addition to critical design decisions, we use the established NIFS FfP framework to discuss the quality of the NIFS in meeting the intended objectives. We highlight aspects that work well and other survey traits requiring further evaluation. Differences found in comparing the NIFS to the National Flu Survey, the National Health Interview Survey, and Behavioral Risk Factor Surveillance System are discussed via their respective FfP characteristics. The findings presented here highlight the importance of the FfP framework for designing surveys, defining data quality, and providing a set a metrics used to advertise the intended use of the survey data and results.

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
INTRODUCTION Vaccination helps to prevent influenza infection and reduce associated costs but the influenza vaccination rate in Texas for adults between the ages of 18 to 64 years old is the lowest in the US. Pharmacies and alternative locations have been shown to help increase vaccination rates but many adults still go unvaccinated. OBJECTIVE This research aims to determine the factors associated with obtaining influenza vaccination at the pharmacy compared to non-pharmacy locations in Texas. METHOD This study used pooled Texas Behavior Risk Factor Surveillance System datasets (2014 to 2018) for this assessment. The main outcome variable was categorized into pharmacy and non-pharmacy vaccination locations and analyzed using a logistic regression analysis. Further statistical analysis was done using a multinomial logistic regression after re-categorizing the outcome variable into pharmacy, doctor office, and other locations. RESULT Blacks were 63% (AOR 0.37, C.I. 0.26, 0.50) and Hispanics were 38% (AOR 0.62, C.I. 0.48, 0.80) less likely to receive influenza vaccinations at the pharmacy respectively when compared to Whites. Furthermore, those who did not live in a Metropolitan Statistical Area (MSA) were 33% (AOR 0.67, C.I 0.53, 0.84) less likely to receive influenza vaccinations at the pharmacy compared to those who lived in an MSA. While there was no observed difference in the likelihood of receiving influenza vaccination, the unemployed population were 40% (AOR 1.40, C.I 1.15, 1.71) more likely to be vaccinated in the pharmacy compared to the employed population. CONCLUSION There is potential for increased utilization of pharmacies as a source of influenza vaccination in Texas. Racial differences exist both for receiving influenza vaccinations and being vaccinated in the pharmacy. Influenza vaccination advocacy and education efforts may be necessary to improve pharmacy-based vaccination in Texas, especially for minorities and rural-dwelling Texans.

Abstract
Background Annual influenza vaccination is recommended for all patients with cancer, but vaccine uptake data by cancer type and time since diagnosis are limited. We sought to estimate vaccination rates across different cancer types in the United States and determine whether rates vary over time since diagnosis. Methods Vaccination rates in individuals with solid tumor and hematological malignancies were estimated using data from 59 917 individuals obtained by the 2016 and 2017 National Health Interview Survey conducted by the Centers for Disease Control and Prevention. Results An average of 64% of the 5053 individuals with self-reported cancer received the influenza vaccine. Vaccination rates in men and women with solid tumors (66.6% and 60.3%, respectively) and hematological malignancies (58.1% and 59.2%, respectively) were significantly higher compared to those without cancer (38.9% and 46.8%, respectively). Lower rates were seen in uninsured patients, those younger than 45 years of age, and in African Americans with hematological malignancies but not with solid tumors. Vaccine uptake was similar regardless of time since cancer diagnosis. Conclusions Influenza vaccination rates are higher in men and women with cancer but remain suboptimal, highlighting the need for additional measures to improve vaccine compliance and prevent complications from influenza across all cancer types.

Abstract
INTRODUCTION The purpose of this study was to identify predictors of initial hospitalization and describe the outcomes of high-risk patients hospitalized with influenza. METHODS Data were taken from the 5% national US Medicare database from 2012 to 2015. Patients (aged at least 13 years) were required to have at least one diagnosis for influenza and have continuous health plan enrollment for 6 months before (baseline) and 3 months (follow-up) after the date of influenza diagnosis. Patients who died during follow-up were included. Patients were categorized as initially hospitalized if hospitalized within 0-1 day of diagnosis. High-risk initially hospitalized patients were defined as patients aged at least 65 years or those that had a diagnostic code for chronic lung disease, cardiovascular or cerebrovascular disease, or weakened immune system during baseline period. Logistic regression models were developed to determine predictors of initial hospitalization. RESULTS The study population included 8127 high-risk patients who were initially hospitalized and 16,784 who were not hospitalized. Among high-risk patients, 89.3% were diagnosed in the emergency room, whereas 7.5% and 3.2% were diagnosed in a physician's office or other Medicare settings, respectively. Chronic obstructive pulmonary disorder, congestive heart failure, chronic kidney disease, older age, being male, other comorbidities, number of comorbidities, and baseline healthcare resource use were the predictors of hospitalization. Median length of stay for the hospitalization was 5.0 days, and the 30-day readmission rate was 14%. All-cause mortality rate was 5.1% during the inpatient stay and 9.2% within 30 days of diagnosis. Hospitalized patients with influenza incurred an increase of $16,568 per patient in total all-cause healthcare costs from pre-influenza to post-influenza diagnosis. CONCLUSION The study characterized the burden of hospitalization for influenza and found that hospitalized high-risk patients experience greater comorbidity burden, higher likelihood of multiple inpatient admissions, and costly medical interventions compared to patients who were not hospitalized.

[PMID: 33597114 DOI: 10.1016/j.vaccine.2021.01.065] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 01/21/2021] [Accepted: 01/26/2021] [Indexed: 01/01/2023]
Abstract
BACKGROUND In the United States (U.S.), annual influenza vaccination has been recommended for all persons aged ≥6 months with the Healthy People 2020 coverage target of 70%. However, vaccination coverage has remained around 42-49% during the past eight influenza seasons. We sought to quantify influenza vaccination coverage and factors associated with vaccination in persons seeking outpatient medical care for an acute respiratory illness (ARI). METHODS We enrolled outpatients aged ≥6 months with ARI from >50 U.S. clinics from 2011 to 2012 through 2018-2019 influenza seasons and tested for influenza with molecular assays. Vaccination status was based on documented receipt of the current season's influenza vaccine. We estimated vaccination coverage among influenza-negative study participants by study site, age, and season, and compared to state-level influenza coverage estimates in the general population based on annual immunization surveys. We used multivariable logistic regression to examine factors independently associated with receipt of influenza vaccines. RESULTS We enrolled 45,424 study participants with ARI who tested negative for influenza during the study period. Annual vaccination coverage among influenza-negative ARI patients and the general population in the participating states averaged 55% (range: 47-62%), and 52% (range: 46-54%), respectively. Among enrollees, coverage was highest among adults aged ≥65 years (82%; range, 80-85%) and lowest among adolescents aged 13-17 years (38%; range, 35-41%). Factors significantly associated with non-vaccination included non-White race, no college degree, exposure to cigarette smoke, absence of high-risk conditions, and not receiving prior season influenza vaccine. CONCLUSIONS Influenza vaccination coverage over eight seasons among outpatients with non-influenza respiratory illness was slightly higher than coverage in the general population but 15% lower than national targets. Increased efforts to promote vaccination especially in groups with lower coverage are warranted to attain optimal health benefits of influenza vaccine.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:1447.

Abstract
In the US, adult immunization coverage remains low, especially among vulnerable populations, as recent hepatitis A outbreaks have demonstrated. We studied the vaccination history variation among the US adults who use drugs by implementing a community-engaged research survey to identify reported immunization coverage, missed opportunities (MO), and places where immunizations might be delivered. Our analysis of a sample of 1127 participants recruited at community syringe exchanges in three cities identified higher overall vaccination receipt in Los Angeles compared to Atlanta or Las Vegas (e.g., HAV receipt 52.2% LA, 42.1% LV, 41.4% Atlanta). Overall, fewer participants reported having received HAV (45.9%), HBV (47.5%), or influenza (47.6%) vaccines than MMR (57.1%) or Td/Tdap (61.1%). Across sites, HAV receipt was higher for participants incarcerated ≥ 5 years (54.2% vs. 43.6% for those incarcerated < 5 years, 49.4% no incarceration history, p = 0.02). HBV receipt was higher among participants who were not intravenous drug users (56.1% vs. 46.0%, p = 0.03). Additionally, income >$20k predicted higher rates of MMR receipt (67.0% vs. 56.5%, p = 0.009), as did stable housing (62.8% vs. 54.3%, p = 0.01). To address the need to expand vaccine coverage among vulnerable adults, delivering vaccine at sites where persons who use drugs access services, or in correctional facilities, may be warranted.

Abstract
OBJECTIVE Seasonal influenza vaccination is the main method for influenza prevention. The main objective of this study is to estimate the frequency of vaccinations in patients with chronic illnesses presented to a primary health care (PHC) centre. METHODS This cross-sectional study was performed in patients admitted to the Kapandriti Health Centre. Their vaccination status with an influenza vaccine and their underlying diseases were recorded. RESULTS 34.8% of the subjects had been vaccinated against seasonal influenza. Vaccination coverage was found to be 53.9% in pulmonary, 55.6% in chronic kidney disease, 43.7% in cardiovascular disorders, 40.6% in diabetes, 40.6% in any kind of malignancy, and finally 33.3% in neurological patients. The most significant predictors for vaccination were the age group of 60 to 79 years (OR = 3.08, 95% CI: 1.79-5.29), age over 80 years (OR = 2.91, 95% CI: 1.58-5.36), respiratory disease (OR = 2.25, 95% CI: 1.33-3.76), cardiovascular disorder (OR = 1.46, 95% CI: 1.02-2.10), and 3 to 5 visits to the unit annually (OR = 1.57, 95% CI: 1.12-2.24). Finally, it was discovered that coexistence of one to three diseases reduced the likelihood ratio for vaccine uptake (OR = 0.15, 95% CI: 0.03-0.79, p < 0.05). CONCLUSIONS The influenza vaccination rate for the population of the present study has been found higher than that reported previously in literature. We believe that there is a need to implement new and more effective strategies such as educating vulnerable groups on the benefits of vaccination and so reducing the incidence of influenza and its complications especially in vulnerable groups.

Abstract
BACKGROUND To characterize level and predictors of influenza and pneumococcal vaccine uptake among Danish kidney transplant recipients (KTR) and kidney transplant waiting list patients (WLP). METHODS A cross-sectional survey based on self-reported vaccine uptake including WLP and KTR ≤ 1½ years post transplantation. Descriptive statistics and logistic regression analyses identifying factors associated with influenza vaccine uptake in the latest season were performed. RESULTS A total of 220 participants were included in the study, 54% KTR and 46% WLP. Self-reported influenza vaccine uptake in the latest season was overall 41.8%. Uptake of influenza vaccine on any prior season apart from the latest season was 53.2% and significantly higher among WLP than KTR (P = .007). Pneumococcal vaccine uptake was only 4% overall. The only factor positively associated with influenza vaccine uptake in the latest season was any prior influenza vaccine uptake (OR 5.79, CI95 2.44-13.76) (P < .001). Recommendations given by other persons (non-physician) were negatively associated with receiving the influenza vaccination in the latest season (OR 0.34, CI95 0.13-0.92) (P = .03). Reasons for not being vaccinated were primarily lack of information, perception of own good health, and fear of adverse reactions. CONCLUSIONS Influenza and pneumococcal vaccine uptakes were suboptimal among Danish WLP and KTR. Increased awareness about guidelines and physicians´ education are warranted.

Abstract
Background Seasonal influenza epidemics yearly affects 5–15% of the world’s population, resulting in 3–5 million serious cases and up to 650,000 deaths. According to the 2017–2019 Italian National Immunisation Plan, free immunisation is offered to the categories at increased risk of experience the complications of the infection (over 65 years old subjects, pregnant women and individuals with underlying conditions, including chronic heart diseases). Rising evidence suggests that influenza can trigger adverse cardiovascular events therefore the vaccination is recommended for secondary prevention of cardiovascular diseases. Despite this, the influenza coverage rate in subjects with chronic heart disease is underestimated. Methods The study investigated the coverage rate in four consecutive influenza seasons (from 2011/2012 to 2014/2015) in subjects that benefit from exemption from paying healthcare costs for chronic heart disease living in Local Health Unit (LHU) of Ferrara (Italy), comparing the databases of exemptions and immunisations. Results The levels of influenza vaccine uptake were unstable, reaching the 50.3% in 2011/2012 immunisation season and falling to 42.2% in the following year. Coverage rates increased with increasing age, without achieving the 75% target, neither in over 65 years old subjects. The logistic regression analysis showed that influenza coverage rates were statistically significant different (p < 0.0001, 0.003 only for category of disease in 2011/2012 immunisation season) according to age, district of residence, category of chronic heart disease and length of exemption, but not influenced by gender. Conclusions The recommendation of influenza immunisation was weakly followed in individuals with chronic heart diseases. A collaboration between cardiologists, GPs, scientific societies and patient associations could successfully support influenza vaccine uptake.

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.

Abstract
This cross-sectional study assessed knowledge, attitudes, and practices regarding meningococcal disease and related vaccinations among healthcare workers (HCWs) who provided care to patients with underlying high-risk medical conditions. A total of 411 HCWs returned the survey. Only 35% of the respondents had a good knowledge about the incidence and lethality of meningococcal disease, the most frequent serogroups in Italy and the diseases or conditions that expose patients to a high-risk of severe complications caused by meningococcal disease. Vaccination against meningococcal disease was perceived to be highly effective by 38.4% of participants, very safe by 36.2%, and 82% agreed or strongly agreed that HCWs should promote adherence to recommended vaccinations even in hesitant patients. Moreover, 34.1% recommended meningococcal vaccinations to all eligible patients and the results of the multivariate analysis showed that older HCWs, who work in pediatric/neonatal wards, have good knowledge about meningococcal vaccinations, have a favourable attitude towards vaccinations, and do not need additional information about meningococcal vaccinations, were more likely to recommend meningococcal vaccinations to all eligible patients. Interventions aimed at the enhancement of knowledge and awareness of HCWs who provide care to these patients on the benefits of meningococcal vaccinations are warranted.

Abstract
BACKGROUND Annual influenza vaccination has been recommended for all adults since 2010. This study aimed to identify characteristics associated with influenza vaccination among adults. METHODS Data from the National Health Interview Survey from 2011 to 2016 were analyzed. RESULTS Influenza vaccination coverage among adults increased from 38.28% in 2011 to 44.75% in 2016 (1.50% per year on average). In multivariate analysis, the largest magnitude of association was found with pneumococcal vaccine (lowest and highest odds ratios from 2011 to 2016: 3.37-3.78), followed by physician visits ≥4 in the past 12 months (2.33-3.03), age ≥65 years (1.69-2.07), having a usual place for sick care (1.41-1.94), insurance coverage (1.52-1.79), hepatitis B vaccine (1.48-1.71), ratio of family income to the poverty threshold ≥4 (1.19-1.54), race of Asian (1.24-1.47), number of years on the job ≥21 (1.21-1.41), class of worker (Federal government: 1.23-1.32, State government: 1.15-1.38), high-risk conditions (1.13-1.26), physical activity ≥5 times/week (1.11-1.25) and being female (1.13-1.20). However, adults living in West, and adults of Black/African American, never married, high school education, self-employed and current smokers had lower vaccine uptake. CONCLUSIONS Several characteristics were identified to be associated with influenza vaccination uptake, which could be useful for targeted efforts to improve influenza vaccination coverage among adults.

Impact of a Catch-Up Strategy of DT-IPV Vaccination during Hospitalization on Vaccination Coverage among People Over 65 Years of Age in France: The HOSPIVAC Study (Vaccination during Hospitalization). Vaccines (Basel) 2020; 8:vaccines8020292. [PMID: 32527049 PMCID: PMC7349959 DOI: 10.3390/vaccines8020292] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 05/29/2020] [Accepted: 06/04/2020] [Indexed: 11/17/2022] Open
Abstract
In France, diphtheria tetanus and inactivated polio vaccine (DT-IPV) coverage and immunization are insufficient in the elderly and decrease with age. The principal objective of this study was to assess the impact of a strategy of catch-up DT-IPV vaccination during hospitalization in people over the age of 65 years in central France (the Sarthe region). We performed a prospective, single-center, cluster-randomized study (four hospital wards). We included patients aged ≥65 years, without mental impairment, contraindication and who accepted to participate, hospitalized in the internal medicine wards in Le Mans Hospital from 28 May 2018 to 27 May 2019. The DT-IPV vaccination status of the patients was determined at inclusion and the wards were randomized (intervention and control). In the intervention group, vaccination was up-dated during hospitalization. In case of temporary contraindication, vaccination was prescribed at hospital discharge. Patients hospitalized in the control wards received oral information only. Final immunization status was determined by calling the patient's general practitioner two months after hospital discharge. One hundred and fifty seven patients were included: 73 in the intervention and 84 in the control arm. Baseline immunization coverage was 46.5%. Vaccination coverage increased from 56.2% to 80.8% in the intervention group and from 38.1% to 40.5% in the control group (p < 0.001). Having received sufficient information from the general practitioner was the only factor associated with vaccination being up-to-date in uni- and multivariate analysis: OR = 5.07 [2.45-10.51]. In a setting of low vaccination coverage DT-IPV vaccination during hospitalization is an effective catch-up strategy.

Abstract
Seasonal influenza is an important cause of morbidity and mortality, particularly among the elderly population. Determinants of vaccination uptake and its impact on health outcomes in the seasons 2014/2015–2016/2017 in elderly living in Treviso area (Veneto Region, North-Eastern Italy) were evaluated. A retrospective cohort study was conducted combining information from several health administrative databases, and multiple Poisson regression models were applied to evaluate the influenza vaccine effectiveness, also adjusting for confounding factors. MF59-adjuvanted trivalent-inactivated vaccine was mainly administered. Data from more than 83,000 elderly people were analyzed by year. Vaccine coverage was about 50%; influenza vaccination uptake was independently associated with older age, male sex, increasing number of underlying chronic conditions, previous pneumococcal vaccination, annual expenses for specialist medical cares, and general practitioner to whom the elderly was in charge. After adjusting for previously described characteristics, vaccination was associated with lower mortality and influenza-related hospitalization rates. Specifically, during influenza season the adjusted incidence rate ratio of death and of influenza-related hospitalizations for vaccinated compared to unvaccinated persons was 0.63 [95% confidence interval (CI) 0.58–0.69, p < .001] and 0.86 (95% CI 0.81–0.91, p < .001), respectively. A similar effectiveness was estimated for death in all age groups (≤74, 75–84, ≥85 years old), whereas a higher effect was found for hospitalizations in subjects aged ≥75 years old. Vaccination was also effective both in males and females. Findings suggest a health benefit of the influenza vaccination in the elderly population. Efforts should be focused on strategies to increase the vaccination uptake as important instrument of prevention.

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.

Cost-effectiveness of increased influenza vaccination uptake against readmissions of major adverse cardiac events in the US. PLoS One 2019; 14:e0213499.

Abstract
Background Although influenza vaccination has been shown to reduce the incidence of major adverse cardiac events (MACE) among those with existing cardiovascular disease (CVD), in the 2015–16 season, coverage for persons with heart disease was only 48% in the US. Methods We built a Monte Carlo (probabilistic) spreadsheet-based decision tree in 2018 to estimate the cost-effectiveness of increased influenza vaccination to prevent MACE readmissions. We based our model on current US influenza vaccination coverage of the estimated 493,750 US acute coronary syndrome (ACS) patients from the healthcare payer perspective. We excluded outpatient costs and time lost from work and included only hospitalization and vaccination costs. We also estimated the incremental cost/MACE case averted and incremental cost/QALY gained (ICER) if 75% hospitalized ACS patients were vaccinated by discharge and estimated the impact of increasing vaccination coverage incrementally by 5% up to 95% in a sensitivity analysis, among hospitalized adults aged ≥ 65 years and 18–64 years, and varying vaccine effectiveness from 30–40%. Result At 75% vaccination coverage by discharge, vaccination was cost-saving from the healthcare payer perspective in adults ≥ 65 years and the ICER was $12,680/QALY (95% CI: 6,273–20,264) in adults 18–64 years and $2,400 (95% CI: -1,992–7,398) in all adults 18 + years. These resulted in ~ 500 (95% CI: 439–625) additional averted MACEs/year for all adult patients aged ≥18 years and added ~700 (95% CI: 578–825) QALYs. In the sensitivity analysis, vaccination becomes cost-saving in adults 18+years after about 80% vaccination rate. To achieve 75% vaccination rate in all adults aged ≥ 18 years will require an additional cost of $3 million. The effectiveness of the vaccine, cost of vaccination, and vaccination coverage rate had the most impact on the results. Conclusion Increasing vaccination rate among hospitalized ACS patients has a favorable cost-effectiveness profile and becomes cost-saving when at least 80% are vaccinated.

Abstract
INTRODUCTION Extending the benefits of vaccination against infectious diseases from childhood throughout the entire life-span is becoming an increasingly urgent priority in view of the world's aging population, emergence and reemergence of infectious diseases, and the necessity to invest more on prevention versus cure in global healthcare. Areas covered: This perspective discusses how life-course immunization could benefit human health at all stages of life. To achieve this, the current vaccination paradigm should be changed and all stakeholders have a role to play. Expert commentary: To enhance immunization confidence in the population, it is essential that stakeholders eliminate complacency toward infectious diseases, improve vaccination convenience, remove barriers among different healthcare specialties, and address prevention as a single entity. They must also consider societal and cultural mindsets by understanding and including public viewpoints. A new "4Cs' model encompassing convenience, confidence, complacency, and cultural acceptance is proposed to convert 'vaccine availability' to 'vaccination acceptance' throughout life. Life-course vaccination should become the new social norm of a healthy life-style, along with a healthy diet, adequate physical exercise, and not smoking. We are 'all in' to make life-course immunization a gateway for all people to lead longer, healthier lives.

Abstract
BACKGROUND Diseases of immune dysregulation are associated with an increased risk of viral infections, some of which may be preventable. To date, there are very limited data on the incidence and risk of influenza and related complications in patients with inflammatory bowel disease (IBD). Furthermore, the impact of immunosuppressive medications on that risk is unclear. Therefore, the aim of this study was to estimate the incidence and severity of influenza infections in IBD patients. In addition, we looked specifically at the effect of medications on influenza risk. METHODS Using the MarketScan Database (January 2008 to December 2011), we conducted a retrospective cohort study to estimate the incidence of influenza and risk of related complications in IBD patients compared with those without IBD. We employed a nested case-control study design to evaluate the potential independent effect of IBD medications on influenza risk. RESULTS A total of 140,480 patients with IBD and non-IBD controls were studied. There were 2963 patients with influenza compared with 1941 non-IBD subjects. Inflammatory bowel disease patients had an increased influenza risk compared with those without IBD (incidence rate ratio, 1.54; 95% confidence interval [CI], 1.49-1.63). A higher rate of hospitalizations (162/2994 [5.4%] vs 36/1941 [1.85%]; P < 0.001) was noted. Systemic corticosteroids were found to be independently associated with influenza (odds ratio, 1.22; 95% CI, 1.08-1.38). CONCLUSIONS Inflammatory bowel disease patients had an increased risk of influenza compared with those without IBD and were more likely to require hospitalization. Steroids were the only medication class independently associated with flu risk.

Abstract
Objectives To examine temporal trend in uptake of seasonal influenza vaccine (SIV) in the UK and explore disease and demographic factors associated with vaccination. Methods From the Clinical Practice Research Datalink, 32 751 people with auto-immune rheumatic diseases prescribed DMARDs between 2006 and 2016 were identified. The proportion vaccinated between 1 September of one year and 31 March of the next year was calculated and stratified by age, other indications for vaccination, auto-immune rheumatic diseases type and number of DMARDs prescribed. Stata and Joinpoint regression programs were used. Results SIV uptake was high in those aged ⩾65 years (82.3 and 80.7% in 2006–07 and 2015–16, respectively). It was significantly lower in other age groups, but improved over time with 51.9 and 61.9% in the 45–64 year age group, and 32.3 and 50.1% in the <45 year age group being vaccinated in 2006–07 and 2015–16, respectively. While 64.9% of the vaccinations in those ⩾65 years old occurred by 3 November, in time to mount a protective immune response before the influenza activity becomes substantial in the UK, only 38.9% in the 45–64 year and 26.2% in the <45 year age group without any other reason for vaccination received SIV by this date. Women, those with additional indications for vaccination, on multiple DMARDs and with SLE were more likely to be vaccinated. Conclusion SIV uptake is low in the under 65s, and the majority of them are not vaccinated in time. Additional effort is required to promote timely uptake of SIV in this population.

Abstract
INTRODUCTION A proven, but underutilized, method to increase current low vaccination rates is reminder/recall. Centralized reminder/recall using an Immunization Information System reduces the burden of an individual practice conducting reminder/recall. The objectives were to assess the effectiveness of centralized vaccine reminder/recall on improving adult vaccination rates using Colorado's Immunization Information System. STUDY DESIGN This study is a pragmatic RCT. SETTING/PARTICIPANTS Denver Health patients were divided into three strata: 25,039 individuals aged 19-64 years without a high-risk condition for pneumococcal disease, 16,897 individuals aged 19-64 years with a high-risk condition, and 5,332 individuals aged ≥65 years. Data were collected from October 2015 to April 2016 and analyzed between September 2016 and June 2017. INTERVENTION Adults aged 19-64 years without a high-risk condition who needed influenza or tetanus, diphtheria, acellular pertussis vaccine or both, and adults with a high-risk condition and adults aged ≥65 years who needed influenza, or tetanus, diphtheria, acellular pertussis, or pneumococcal vaccine, or all three vaccines were randomized to receive up to three reminder/recalls or usual care. MAIN OUTCOME MEASURES Documentation of receipt of any needed vaccine in Immunization Information System ≤6 months after the reminder/recall was the primary outcome. A secondary outcome included implementation costs of the reminder/recall effort. A mixed effects model assessed the association between the intervention and receipt of any needed vaccine while controlling for gender, age, race, ethnicity, insurance type, and history of vaccine refusal. RESULTS The intervention was associated with receipt of any needed vaccine in the adults aged ≥65 years population (AOR=1.15, 95% CI=1.02, 1.30), but not the other two populations. Influenza vaccine was the source of this difference, with 32.0% receiving a vaccine in intervention versus 28.6% in usual-care groups (p≤0.01). Start-up and implementation costs per person were $0.86. In the population aged ≥65 years, 29.4 patients would need to be contacted to gain one additional vaccination. CONCLUSIONS Centralized reminder/recall was effective at increasing influenza vaccination rates in adults aged ≥65 years over a short time period, without burdening the practices, and at a reasonable cost.

Abstract
Objective The study objective is to analyze influenza vaccination status by demographic factors, perceived vaccine efficacy, social influence, herd immunity, vaccine cost, health insurance status, and barriers to influenza vaccination among adults 18 years and older in the United States. Background Influenza vaccination coverage among adults 18 years and older was 41% during 2010–2011 and has increased and plateaued at 43% during 2016–2017. This is below the target of 70% influenza vaccination coverage among adults, which is an objective of the Healthy People 2020 initiative. Methods We conducted a survey of a nationally representative sample of adults 18 years and older in the United States on factors affecting influenza vaccination. We conducted bivariate analysis using Rao-Scott chi-square test and multivariate analysis using weighted multinomial logistic regression of this survey data to determine the effect of demographics, perceived vaccine efficacy, social influence, herd immunity, vaccine cost, health insurance, and barriers associated with influenza vaccination uptake among adults in the United States. Results Influenza vaccination rates are relatively high among adults in older age groups (73.3% among 75 + year old), adults with education levels of bachelor’s degree or higher (45.1%), non-Hispanic Whites (41.8%), adults with higher incomes (52.8% among adults with income of over $150,000), partnered adults (43.2%), non-working adults (46.2%), and adults with internet access (39.9%). Influenza vaccine is taken every year by 76% of adults who perceive that the vaccine is very effective, 64.2% of adults who are socially influenced by others, and 41.8% of adults with health insurance, while 72.3% of adults without health insurance never get vaccinated. Facilitators for adults getting vaccinated every year in comparison to only some years include older age, perception of high vaccine effectiveness, higher income and no out-of-pocket payments. Barriers for adults never getting vaccinated in comparison to only some years include lack of health insurance, disliking of shots, perception of low vaccine effectiveness, low perception of risk for influenza infection, and perception of risky side effects. Conclusion Influenza vaccination rates among adults in the United States can be improved towards the Healthy People 2020 target of 70% by increasing awareness of the safety, efficacy and need for influenza vaccination, leveraging the practices and principles of commercial and social marketing to improve vaccine trust, confidence and acceptance, and lowering out-of-pocket expenses and covering influenza vaccination costs through health insurance.

Abstract
OBJECTIVE Patients with chronic conditions have higher rates of severe influenza-related illness and mortality. However, influenza vaccination coverage in high-risk populations continues to be suboptimal. We describe the association between cumulative disease morbidity, measured by a previously validated multimorbidity index, and influenza vaccination among community-dwelling adults. METHODS We obtained interview and medical record data for participants ≥18 years who sought outpatient care for influenza-like illness between 2011 and 2016 as part of an outpatient-based study of influenza vaccine effectiveness. We defined cumulative disease morbidity by using medical diagnosis codes to calculate a multimorbidity-weighted index (MWI) for each participant. MWI and influenza vaccination status was evaluated by logistic regression. Akaike information criterion was calculated for all models. RESULTS Overall, 1458 (48%) of participants out of a total of 3033 received influenza vaccination. The median MWI was 0.9 (IQR 0.00-3.5) and was higher among vaccinated participants (median 1.6 versus 0.0; p < 0.001). We found a positive linear association between MWI and vaccination, and vaccination percentages were compared between categories of MWI. Compared to patients with no multimorbidity (MWI = 0), odds of vaccination were 17% higher in the second category (MWI 0.01-1.50; [OR: 1.17, 95% CI: 0.92-1.50]), 58% higher in the third category (MWI 1.51-3.00; [OR: 1.58, 95% CI: 1.26-1.99]), 130% higher in the fourth category (MWI 3.01-6.00; [OR: 2.30, 95% CI: 1.78-2.98]) and 214% higher in the fifth category (MWI 6.01-45.00;[OR: 3.14, 95% CI: 2.41-4.10]). Participants defined as high-risk had 86% greater odds of being vaccinated than non-high-risk individuals (OR: 1.86, 95% CI: 1.56-2.21). The AIC was lowest for MWI compared with high-risk conditions. CONCLUSIONS Our results suggest a dose response relationship between level of multimorbidity and likelihood of influenza vaccination. Compared with high-risk condition designations, MWI provided improved precision and a better model fit for the measurement of chronic disease and influenza vaccination.

Nowak GJ, Cacciatore MA, Len-Ríos ME. Understanding and Increasing Influenza Vaccination Acceptance: Insights from a 2016 National Survey of U.S. Adults. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15040711. [PMID: 29642624 PMCID: PMC5923753 DOI: 10.3390/ijerph15040711] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Revised: 04/05/2018] [Accepted: 04/07/2018] [Indexed: 11/16/2022]
Abstract
Background: The percentage of adults in the U.S. getting seasonal influenza vaccination has not changed significantly since 2013 and remains far below the federal government's 70% target. Objective: This study assessed and identified characteristics, experiences, and beliefs associated with influenza vaccination using a nationally representative survey of 1005 U.S. adults 19 years old and older. Methods: The sample was drawn from the National Opinion Research Center's AmeriSpeak Panel, a probability-based panel designed to be representative of the U.S. household population. Results: Overall, 42.3% received an influenza vaccination in the past 12 months, with rates highest for non-Hispanic Whites and Blacks and those 65 years old and older. Hispanic respondents and those under 64 years old were much less likely to get an influenza vaccination. They were also less aware of the recommendation, less informed about influenza and the benefits of vaccination, and least confident in the vaccine. Conclusions: Increasing influenza vaccination coverage in the U.S. requires a greater focus on 19-64 year-olds, particularly those 50 to 64, Hispanics and continued focus on those with diabetes and asthma. Efforts need to increase awareness of influenza vaccination recommendations, foster a sense of being well informed about influenza vaccination benefits and the risks associated with non-vaccination, and increase confidence that there are meaningful benefits from receiving an influenza vaccination.

Abstract
Objectives Influenza vaccination (IV) coverage remains low in France. Objectives were to assess patient knowledge and behaviors and missed opportunities for vaccination (MO) and their impact on vaccine uptake. Methods This is a prospective-observational study, including emergency department patients at risk for severe influenza. Patients were interviewed about their knowledge and behaviors. We evaluated the health-care voucher scheme (HCVS) and MO. Results 868 patients were included. Vaccine uptake was 33.2%, 42% of patients knew about the possible severity of influenza, 23% thought that they were not at risk for severe influenza, 39% knew that they have an indication for the vaccine, and 4.3% to 11.5% expressed reservations concerning IV side effects and effectiveness. HCVS was used by 44.3% of patients, but only 14.8% had been vaccinated. MO were reported by 484 patients (69.4%) declaring 1104 consultations and 148 IV propositions (86.6%). Predictors of vaccine uptake (p<0.0001) were: knowledge of serious and fatal influenza forms [OR 0.36 (CI95% 0.25–0.5)]; confidence in influenza vaccine effectiveness [0.38 (0.2–0.7)]; opposition to vaccines [0.22 (0.1–0.48)]; visit to general practitioner [4.53 (2.9–7.1)]; general practitioner proposed IV [2.1 (1.2–3.4)]. Conclusion Our results indicate that high rate of missed opportunities, some patient behaviors and general practitioner visits may explain low influenza vaccine uptake, and that HCVS use is a complex process. Of interest, we found that the patient’s knowledge of the potential severity of influenza is not sufficient to promote vaccine, suggesting that the information strategy must be adapted to each patient behavior.

[PMID: 29329685 DOI: 10.1016/j.vaccine.2017.12.016] [Citation(s) in RCA: 77] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Revised: 12/04/2017] [Accepted: 12/06/2017] [Indexed: 01/01/2023]
Abstract
BACKGROUND Influenza vaccination has been recommended for all persons aged ≥6 months since 2010. METHODS Data from the 2016 National Internet Flu Survey were analyzed to assess provider vaccination recommendations and early influenza vaccination during the 2016-17 season among adults aged ≥18 years. Predictive marginals from a multivariable logistic regression model were used to identify factors independently associated with early vaccine uptake by provider vaccination recommendation status. RESULTS Overall, 24.0% visited a provider who both recommended and offered influenza vaccination, 9.0% visited a provider who only recommended but did not offer, 25.1% visited a provider who neither recommended nor offered, and 41.9% did not visit a doctor from July 1 through date of interview. Adults who reported that a provider both recommended and offered vaccine had significantly higher vaccination coverage (66.6%) compared with those who reported that a provider only recommended but did not offer (48.4%), those who neither received recommendation nor offer (32.0%), and those who did not visit a doctor during the vaccination period (28.8%). Results of multivariable logistic regression indicated that having received a provider recommendation, with or without an offer for vaccination, was significantly associated with higher vaccination coverage after controlling for demographic and access-to-care factors. CONCLUSIONS Provider recommendation was significantly associated with influenza vaccination. However, overall, 67.0% of adults did not visit a doctor during the vaccination period or did visit a doctor but did not receive a provider recommendation. Evidence-based strategies such as client reminder/recall, standing orders, provider reminders, or health systems interventions in combination should be undertaken to improve provider recommendation and influenza vaccination coverage. Other factors significantly associated with a higher level of influenza vaccination included age ≥50 years, being Hispanic, having a college or higher education, having a usual place for medical care, and having public health insurance.

Abstract
BACKGROUND Adults with chronic conditions are at much greater risk of influenza-related morbidity and mortality, yet flu vaccine uptake remains suboptimal. Research focused on the high-risk population has been limited, particularly related to racial disparities in vaccination. We explore a broad range of demographic, racial, and psychosocial factors to identify predictors of vaccination among high-risk adults, with a focus on identify differences between Black and White adults. METHODS We conducted an online survey in March 2015, utilizing international research firm GfK's KnowledgePanel, for a nationally representative sample of Black and White adults (≥18, USA) and limited analysis adults with high-risk of influenza-related complications. Using two-way ANOVA, we assessed demographic, racial, and psychosocial predictors across vaccine uptake in the past five years and across racial group. RESULTS 424 (52.2%) Black and 388 (47.8%) White respondents with high-risk complications completed the survey. 383 (47.3%) reported vaccination annually, 99 (12.2%) most years, 104 (12.9%) once/twice, and 223 (27.6%) never.ANOVA confirmed significant differences in vaccine behavior for most demographic predictors (except education), all racial factors (including racial fairness, experiences of discrimination, etc.), and most psychosocial factors (including vaccine attitudes, trust in the vaccine, etc.). ANOVA confirmed significant differences for most factors by race. We observed significant interaction effects between race and vaccine behavior for subjective social status, access to medical care, knowledge of vaccine recommendations, vaccine attitudes, perceived side effect risks, descriptive norms, subjective norms, flu vaccine hesitancy, and flu vaccine confidence, thus implying racial differences in the connection between vaccine uptake and key demographic, racial, and psychosocial factors. CONCLUSIONS This study provides a novel examination of flu vaccine behavior among high-risk Blacks and Whites that identified factors influencing vaccine uptake.We found significant differences by race. Health care professionals can use this information to more effectively target high-risk adults during flu season.

Abstract
BACKGROUND Influenza A(H1N1) causes serious complications in immunocompromised patients. The efficacy of seasonal vaccination in these patients has been questioned. AIM To describe two outbreaks of influenza A(H1N1) in immunocompromised patients. METHODS Two outbreaks of influenza A(H1N1) occurred in our institution: on the kidney transplant ward in 2014 including patients early after kidney or simultaneous pancreas-kidney transplantation, and on the oncology ward in 2016 including patients receiving chemotherapy for malignant tumours. Factors leading to these outbreaks and the clinical efficacy of seasonal influenza vaccination were analysed. FINDINGS Altogether 86 patients were exposed to influenza A(H1N1) during the outbreaks, among whom the seasonal influenza vaccination status was unknown in 10. Only three out of 38 vaccinated patients were infected with influenza A(H1N1), compared with 20 out of 38 unvaccinated patients (P = 0.02). The death of one out of 38 vaccinated patients was associated with influenza, compared with seven out of 38 unvaccinated patients (P = 0.06). Shared factors behind the two outbreaks included outdated facilities not designed for the treatment of immunosuppressed patients. Vaccination coverage among patients was low, between 40% and 70% despite vaccination being offered to all patients free of charge. Vaccination coverage of healthcare workers on the transplant ward was low (46%), but, despite high coverage on the oncology ward (92%), the outbreak occurred. CONCLUSION Seasonal influenza vaccination was clinically effective with both a reduced risk of influenza infection and a trend towards reduced mortality in these immunocompromised patients. Several possible causes were identified behind these two outbreaks, requiring continuous awareness in healthcare professionals to prevent further outbreaks.

Abstract
OBJECTIVES To compare changes in vaccination rates (pneumococcal polysaccharide vaccine [PPSV]; tetanus, diphtheria, and pertussis [Tdap] vaccine; and influenza vaccine) among high-risk adults following an intervention (June 1, 2013, to January 31, 2015) that used the 4 Pillars Practice Transformation Program (4 Pillars Program). STUDY DESIGN Post hoc analysis of data from a randomized controlled cluster trial. METHODS Eighteen primary care practices received staff education, guidance for using the 4 Pillars Program, and support for a practice immunization champion. Paired t tests were used to compare vaccination rates separately for those with diabetes, chronic lung or chronic heart disease, or other high-risk conditions. Student's t tests were used to compare vaccination rates across high-risk conditions. Generalized estimating equation modeling was used to determine the likelihood of vaccination. RESULTS Based on International Classification of Diseases, Ninth Revision, Clinical Modification codes, 4737 patients aged 18 to 64 years were identified as having diabetes (n = 1999), chronic heart disease (n = 658), chronic lung disease (n = 1682), or another high-risk condition (n = 764). PPSV uptake increased by 12.2 percentage points (PP), Tdap vaccination increased by 11.4 PP, and influenza vaccination increased by 4.8 PP. In regression analyses, patients with diabetes (odds ratio [OR], 2.2; 95% CI, 1.80-2.73), chronic lung disease (OR, 1.50; 95% CI, 1.21-1.87), or chronic heart disease (OR, 1.32; 95% CI, 1.02-1.71) were more likely to receive PPSV than those without the respective high-risk condition. Those with diabetes (OR, 1.14; 95% CI, 1.01-1.28) or chronic lung disease (OR, 1.14; 95% CI, 1.01-1.30) were more likely to receive an influenza vaccine than those without the respective condition. The likelihood of Tdap vaccination was not significantly associated with any of the chronic conditions tested. CONCLUSIONS An intervention including the 4 Pillars Program was associated with significant increases in vaccination of high-risk adults. However, the overall uptake of recommended vaccines for those with high-risk conditions remained below national goals.

Public Perception of the Risks Associated with Infectious Diseases in Poland: Ebola and Influenza and Their Impact on the Attitude to Vaccination. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2017; 980:27-36.

Abstract
While the Ebola outbreak in 2014 was strongly highlighted in mainstream media and perceived as a threat to public health in Poland, influenza was regarded as a triviality and the vaccination coverage was low. In the present study, by analyzing feedback from an on-line questionnaire (from November 2014 to January 2015) we assessed the knowledge concerning Ebola and influenza together with attitudes to immunization of 544 respondents (45% medical staff). The findings were that 92.6% of respondents declared readiness to vaccination before traveling to endemic regions if a vaccine against Ebola would have existed, but adverse reactions, high costs, and low effectiveness would adversely affect that decision. While 84.2% of respondents declared awareness of influenza attributing significantly to the cause of death, only 65.4% considered influenza as an actual danger for people in Poland and 46.7% thought that Poland was not an endemic region for influenza. Nearly 23% declared that they were already vaccinated against influenza. The majority of respondents (67.5%) were not going to be vaccinated. We conclude that awareness of risk related to infectious diseases is an important determinant when deciding whether to vaccinate. However, negative information about the vaccine has some bearing on the decision to get vaccinated.

Abstract
Diabetes mellitus imposes a significant and increasing burden on society, with major consequences for human health, welfare and the economy worldwide. Persons with diabetes mellitus are at increased risk of developing severe complications after influenza virus infection and guidelines advise vaccination. The present evidence for influenza vaccine effectiveness in persons with diabetes mellitus is mainly based on observational studies with clinical endpoints like hospitalization and death, indicating a beneficial reduction of morbidity and mortality. Further supportive evidence comes from serological studies, in which persons with diabetes mellitus usually develop similar antibody levels after vaccination as healthy people. Observational studies may be prone to selection bias, and serological studies may not completely mirror vaccine effectiveness in the field. Although more controlled trials in persons with diabetes mellitus with laboratory-confirmed, influenza-specific outcomes would be desirable to better estimate the effect of vaccination, the currently available data justify routine influenza vaccination in persons with diabetes mellitus. As in this risk group, the use of influenza vaccine is far below target worldwide, efforts should be made to increase vaccination coverage.

Abstract
BACKGROUND Since 2010, the Advisory Committee on Immunization Practices (ACIP) has recommended that all persons aged ≥6months receive annual influenza vaccination. METHODS We analyzed data from the 2015 National Internet Flu Survey (NIFS), to assess knowledge and awareness of the influenza vaccination recommendation and early influenza vaccination coverage during the 2015-16 season among adults. Predictive marginals from a multivariable logistic regression model were used to identify factors independently associated with adults' knowledge and awareness of the vaccination recommendation and early vaccine uptake during the 2015-16 influenza season. RESULTS Among the 3301 respondents aged ≥18years, 19.6% indicated knowing that influenza vaccination is recommended for all persons aged ≥6months. Of respondents, 62.3% indicated awareness that there was a recommendation for influenza vaccination, but did not indicate correct knowledge of the recommended age group. Overall, 39.9% of adults aged ≥18years reported having an influenza vaccination. Age 65years and older, being female, having a college or higher education, not being in work force, having annual household income ≥$75,000, reporting having received an influenza vaccination early in the 2015-16 season, having children aged ≤17years in the household, and having high-risk conditions were independently associated with a higher correct knowledge of the influenza vaccination recommendation. CONCLUSIONS Approximately 1 in 5 had correct knowledge of the recommendation that all persons aged ≥6months should receive an influenza vaccination annually, with some socio-economic groups being even less aware. Clinic based education in combination with strategies known to increase uptake of recommended vaccines, such as patient reminder/recall systems and other healthcare system-based interventions are needed to improve vaccination, which could also improve awareness.

Abstract
BACKGROUND Adults are recommended to receive select vaccinations based on their age, underlying medical conditions, lifestyle, and other considerations. Factors associated with awareness of vaccine-preventable diseases and recommended vaccines among adults in the United States have not been explored. METHODS Data from a 2015 internet panel survey of a nationally representative sample of U.S. adults aged ≥19years were analyzed to assess awareness of selected vaccine-preventable diseases and recommended vaccines for adults. A multivariable logistic regression model with a predictive marginal approach was used to identify factors independently associated with awareness of selected vaccine-preventable infections/diseases and corresponding vaccines. RESULTS Among the surveyed population, from 24.6 to 72.1% reported vaccination for recommended vaccines. Awareness of vaccine-preventable diseases among adults aged ≥19years ranged from 63.4% to 94.0% (63.4% reported awareness of HPV, 71.5% reported awareness of tetanus, 72.0% reported awareness of pertussis, 75.4% reported awareness of HZ, 75.8% reported awareness of hepatitis B, 83.1% reported awareness of pneumonia, and 94.0% reported awareness of influenza). Awareness of the corresponding vaccines among adults aged ≥19years ranged from 59.3% to 94.1% (59.3% HZ vaccine, 59.6% HPV vaccine, 64.3% hepatitis B vaccine, 66.2% pneumococcal vaccine, 86.3% tetanus vaccines, and 94.1% influenza vaccine). In multivariable analysis, being female and being a college graduate were significantly associated with a higher level of awareness for majority of vaccine-preventable diseases, and being female, being a college graduate, and working as a health care provider were significantly associated with a higher level of awareness for majority of corresponding vaccines. CONCLUSIONS Although adults in this survey reported high levels of awareness for most vaccines recommended for adults, self-reported vaccination coverage was not optimal. Combining interventions known to increase uptake of recommended vaccines, such as patient reminder/recall systems and other healthcare system-based interventions, and ensuring patients' vaccination needs are assessed, are needed to improve vaccination of adults.

Using the 4 pillars™ practice transformation program to increase adult influenza vaccination and reduce missed opportunities in a randomized cluster trial. BMC Infect Dis 2016; 16:623. [PMID: 27809793 PMCID: PMC5094034 DOI: 10.1186/s12879-016-1940-1] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2016] [Accepted: 10/18/2016] [Indexed: 11/17/2022] Open
Abstract
Background An evidence-based, step-by-step guide, the 4 Pillars™ Practice Transformation Program, was the foundation of an intervention to increase adult immunizations in primary care and was tested in a randomized controlled cluster trial. The purpose of this study is to report changes in influenza immunization rates and on factors related to receipt of influenza vaccine. Methods Twenty five primary care practices were recruited in 2013, stratified by city (Houston, Pittsburgh), location (rural, urban, suburban) and type (family medicine, internal medicine), and randomized to the intervention (n = 13) or control (n = 12) in Year 1 (2013-14). A follow-up intervention occurred in Year 2 (2014-15). Demographic and vaccination data were derived from de-identified electronic medical record extractions. Results A cohort of 70,549 adults seen in their respective practices (n = 24 with 1 drop out) at least once each year was followed. Baseline mean age was 55.1 years, 35 % were men, 21 % were non-white and 35 % were Hispanic. After one year, both intervention and control arms significantly (P < 0.001) increased influenza vaccination, with average increases of 2.7 to 6.5 percentage points. In regression analyses, likelihood of influenza vaccination was significantly higher in sites with lower percentages of patients with missed opportunities (P < 0.001) and, after adjusting for missed opportunities, the intervention further improved vaccination rates in Houston (lower baseline rates) but not Pittsburgh (higher baseline rates). In the follow-up intervention, the likelihood of vaccination increased for both intervention sites and those that reduced missed opportunities (P < 0.005). Conclusions Reducing missed opportunities across the practice increases likelihood of influenza vaccination of adults. The 4 Pillars™ Practice Transformation Program provides strategies for reducing missed opportunities to vaccinate adults. Trial registration This study was registered as a clinical trial on 03/20/2013 at ClinicalTrials.gov, Clinical Trial Registry Number: NCT01868334, with a date of enrollment of the first participant to the trial of April 1, 2013.
