Abstract
PURPOSE To understand motivators, concerns, and factors associated with COVID-19 vaccine initiation for adults in five racial/ethnic communities across Colorado. METHODS Community-based data collectors surveyed participants from five Colorado communities (urban and rural Latina/o/x, urban Black, rural African American immigrant, and urban American Indian) about vaccine attitudes, intentions, and uptake from September to December 2021. Bivariate and multivariable logistic regression models were used to examine factors associated with the primary outcome of COVID-19 vaccine "initiation." RESULTS Most participants (71.1%) reported having initiated COVID-19 vaccination; vaccine series completion was 65.1%. Both motivators and concerns about COVID-19 vaccines were prevalent. Vaccine hesitancy (OR: 0.41, 95% CI:0.32-0.53; p < .001) and low perceptions of COVID-19 vaccination social norms (OR: 0.48, 95% CI:0.27-0.84; p = .01) were associated with vaccine initiation. CONCLUSION Despite the limitation of a moderate sample size, our findings support the need for further interventions to increase vaccination against COVID-19 by reducing vaccine hesitancy and improving perceived social norms of vaccination in underserved Colorado communities. IMPLICATIONS To improve trust in vaccines and promote vaccine uptake, community messaging should be tailored to vaccination motivators and concerns and demonstrate COVID-19 vaccination as the community default.

A Descriptive Study of Maternal Vaccination Uptake, Attitudes, and Beliefs in Pregnancy Among Persons Delivering at an Urban Safety Net Hospital. WOMEN'S HEALTH REPORTS (NEW ROCHELLE, N.Y.) 2023; 4:288-297. [PMID: 37363358 PMCID: PMC10285378 DOI: 10.1089/whr.2023.0032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Accepted: 05/10/2023] [Indexed: 06/28/2023]
Abstract
Objective To estimate uptake of influenza, tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap), and COVID-19 vaccines during pregnancy and describe vaccine attitudes and beliefs among predominantly racial and ethnic minority individuals delivering at a publicly funded hospital. Methods We collected survey and electronic medical record data for English-speaking postpartum individuals who delivered a live-born infant from July 7, 2022, through August 21, 2022, and agreed to participate in our study. The 58-item survey included questions about general vaccine attitudes and beliefs as well as vaccine-specific questions. We calculated rates of influenza, Tdap, and COVID-19 vaccinations and compared distributions of survey responses by number (no vaccines, one vaccine, or two or three of the recommended vaccines) and type of vaccines received during pregnancy. Results Of the 231 eligible individuals, 125 (54.1%) agreed to participate. Rates of influenza, Tdap, and COVID-19 vaccination were 18.4%, 48.0%, and 5.6% respectively. A total of 61 (48.8%) did not receive any recommended vaccines during pregnancy, 40 (32.0%) received one vaccine, and 24 (19.0%) received two or three vaccines. Approximately 66.1% of the no vaccine group, 81.6% of the one vaccine group, and 87.5% of the two or three vaccine group strongly agreed or agreed that they trusted the vaccine information provided by their obstetrician or midwife. While most (>69.2%) agreed that the vaccine-preventable diseases were dangerous for pregnant women, only 24.0%, 29.3%, and 40.3% agreed that they were worried about getting influenza, whooping cough, or COVID-19, respectively, while pregnant. Discussion Vaccine uptake in our population was low and may be due, in part, to low perceived susceptibility to vaccine-preventable diseases. Obstetricians and midwives were trusted sources of vaccine information, suggesting that enhanced communication strategies could be critical for addressing maternal vaccine hesitancy, particularly in communities of color justifiably affected by medical mistrust.

Abstract
BACKGROUND AND OBJECTIVE Vaccine uptake during pregnancy remains low. Our objectives were to describe 1) development and adaptation of a clinician communication training intervention for maternal immunizations and 2) obstetrics and gynecology (ob-gyn) clinician and staff perspectives on the intervention and fit for the prenatal care context. METHODS Design of the Motivational Interviewing for Maternal Immunizations (MI4MI) intervention was based on similar communication training interventions for pediatric settings and included presumptive initiation of vaccine recommendations ("You're due for two vaccines today") combined with motivational interviewing (MI) for hesitant patients. Interviews and focus group discussions were conducted with ob-gyn clinicians and staff in five Colorado clinics including settings with obstetric physicians, certified nurse midwives (CNMs), and clinician-trainees. Participants were asked about adapting training to the ob-gyn setting and their implementation experiences. Feedback was incorporated through iterative changes to training components. RESULTS Interview and focus group discussion results from participants before (n = 3), during (n = 11) and after (n = 25) implementation guided intervention development and adaptation. Three virtual, asynchronous training components were created: a video and two interactive modules. This virtual format was favored due to challenges attending group meetings; however, participants noted opportunities to practice skills through role-play were lacking. Training modules were adapted to include common challenging vaccine conversations and live-action videos. Participants liked interactive training components and use of adult learning strategies. Some participants initially resisted the presumptive approach but later found it useful after applying it in their practices. Overall, participants reported that MI4MI training fit well with the prenatal context and recommended more inclusion of non-clinician staff. CONCLUSIONS MI4MI training was viewed as relevant and useful for ob-gyn clinicians and staff. Suggestions included making training more interactive, and including more complex scenarios and non-clinician staff.

Abstract
OBJECTIVE This meta-analysis aimed to assess the level of intent to receive coronavirus disease 2019 (COVID-19) vaccination and demographical factors influencing vaccine uptake among pregnant individuals. STUDY DESIGN PubMed, Scopus, and archive/pre-print servers were searched up to May 22nd, 2021. Cross sectional surveys reporting the percentage of the pregnant individuals intending to get a COVID-19 vaccine were considered eligible for meta-analysis. This review was registered with PROSPERO (CRD42021254484). The primary outcome was to estimate the prevalence of COVID-19 vaccination intent among pregnant population. The secondary outcome was to evaluate the factors influencing the intention for vaccination. RESULTS Twelve studies sourcing data of 16,926 individuals who were identified as pregnant were eligible. The estimated intention for the receipt of COVID-19 vaccine among women who were pregnant was 47% (95% CI: 38-57%), with the lowest prevalence in Africa 19% (95% CI: 17-21%) and the highest in Oceania 48.0% (95% CI: 44.0-51.0%). Uptake of other vaccines (influenza and/or TdaP) during pregnancy was associated with higher rate of intent to receive the COVID-19 vaccine (OR = 3.03; 95% CI: 1.37-6.73; p = 0.006). CONCLUSION The intent to receive COVID-19 vaccine is relatively low among women who are pregnant and substantially varies based on the country of residence. In our meta-analysis, intent of women who were pregnant to receive the COVID-19 vaccine was significantly associated with the history of receiving influenza or TdaP vaccine during pregnancy. Given that in every country only a minority of gravidae have received the COVID-19 vaccine, despite known risks of maternal morbidity and mortality with no evidence of risks of vaccination, it highlights the importance of revised approaches at shared decision making and focused public health messaging by national and international advisories. KEY POINTS · The estimated global intention for COVID-19 vaccination among pregnant women was 47%.. · The lowest intention was in Africa and the highest in Oceania.. · These findings highlight the importance of public health messaging by by different agencies..

Abstract
INTRODUCTION Antepartum Tdap remains low despite national recommendations. This prospective observational study aims to identify factors associated with lower antepartum Tdap rates. METHODS Maternal demographics, personal health beliefs, Tdap vaccination status, and recall of in-office obstetric provider actions were collected from a convenience sample of postpartum women in a New York metropolitan hospital. Bivariate and multivariable logistic regression were used to identify significant factors and adjusted odds ratios (OR) for recorded Tdap; OR > 1 reflects elements with increased odds of not receiving antepartum Tdap, while OR < 1 demonstrates increased odds of receipt. RESULTS Surveys were collected (n = 1682) from a study population demographically similar to New York City and more diverse in race/ethnicity than the national population. Demographic analysis showed Hispanic women less likely than white, non-Hispanic women to vaccinate (OR 2.44, CI 1.54-3.88). Health beliefs associated with non-receipt of antepartum Tdap included "It is dangerous for pregnant women to get vaccines" (OR 1.68, CI 1.01-2.77), and "I worry about the safety of the Tdap vaccine" (OR 1.59, CI 1.12-2.24). Obstetric provider actions associated with vaccination included receiving an OB recommendation (OR 0.39, CI 0.23-0.65), getting written information about Tdap (OR 0.44, CI 0.30-0.64), and having Tdap offered in office (OR 0.24, CI 0.15-0.37). Health beliefs associated with antepartum Tdap included "I generally do what my OB/GYN provider recommends" (OR 0.49, CI 0.30-0.80), and "Pregnant women should get the Tdap (pertussis) vaccine" (OR 0.17, CI 0.09-0.33). DISCUSSION Maternal race/ethnicity, personal health beliefs, and obstetric provider actions predict antepartum Tdap.

Abstract
OBJECTIVES To evaluate the concordance between maternal report of antepartum tetanus, diphtheria, pertussis (Tdap) vaccination and vaccination status documented in the electronic medical record (EMR), as well as factors associated with discordance. STUDY DESIGN A survey was completed by a convenience sample of postpartum patients in a New York metropolitan hospital. The survey collected patients' demographic information, health beliefs, and whether they received Tdap vaccine during this pregnancy. The patient's Tdap vaccination status was abstracted from the EMR, a combination of data gathered from the obstetrician and patient's hospital record. Kappa statistics measured the agreement between maternal report and EMR on antepartum Tdap vaccination. Univariate and multivariable logistic regression analyses were performed to identify maternal characteristics associated with discordance. RESULTS Of the 1571 patients with Tdap status available in the EMR, 1549 patients (92%) reported on receipt status for Tdap vaccination during pregnancy; 1328 maternal reports (86%) agreed with the EMR for Tdap status (kappa = 0.72, 95% CI 0.68-0.75). Several factors were statistically significant in multivariable analyses: lower income was associated with greater discordance (ie, overreporting; P = .02), as well as certain health beliefs including "Pregnant women should be concerned about the possibility of pertussis in their babies" (aOR 2.86, 95% CI 1.02-8.04) and "My friends would probably think getting a Tdap vaccine is a good idea" (aOR 2.36, 95% CI 1.11-4.99). CONCLUSIONS Maternal recall of Tdap vaccination during pregnancy is consistent with the EMR. This supports the value of maternal report in determining Tdap vaccination status, which is especially important when vaccination records are not available.

Abstract
OBJECTIVES Although disparities in maternal vaccine acceptance among racial/ethnic groups are well documented, the reasons for these disparities are unclear. The objective of this study was to describe differences in pregnant women's knowledge, attitudes, beliefs, intentions, and trust regarding maternal and infant vaccines by race/ethnicity. METHODS We collected survey data from 1862 pregnant women from diverse prenatal care practices in Georgia and Colorado from June 2017 through July 2018. We performed multiple logistic regressions to determine differences in intentions, knowledge, attitudes, beliefs, and trust by race/ethnicity and calculated odds ratios (ORs) and 95% CIs. RESULTS Compared with White women, Black and Hispanic women were less confident in vaccine safety and efficacy and less likely to perceive risk of acquiring vaccine-preventable diseases, report provaccine social norms, indicate having enough vaccine knowledge, and trust vaccine information from health care providers and public health authorities. Black women were the least confident in the safety of the maternal influenza vaccine (OR = 0.37; 95% CI, 0.27-0.49); maternal tetanus, diphtheria, and acellular pertussis vaccine (OR = 0.37; 95% CI, 0.27-0.52); and infant vaccines overall (OR = 0.40; 95% CI, 0.28-0.58), and were least likely to intend to receive both maternal vaccines (OR = 0.35; 95% CI, 0.27-0.47) or all infant vaccines on time (OR = 0.45; 95% CI, 0.34-0.61) as compared with White women. CONCLUSIONS Understanding differences in behavioral constructs integral to vaccine decision making among women of different races/ethnicities can lead to tailored interventions to improve vaccine acceptance.

Effect of educational and financial incentive-based interventions on immunization attitudes, beliefs, intentions and receipt among close contacts of pregnant women. Vaccine 2021; 39:961-967. [PMID: 33423837 DOI: 10.1016/j.vaccine.2020.12.067] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 12/17/2020] [Accepted: 12/23/2020] [Indexed: 10/22/2022]
Abstract
INTRODUCTION Cocooning, the vaccination of close contacts of a newborn, is a strategy to limit the risk of pertussis and influenza infection among vulnerable infants. METHODS Pregnant women in Colorado and Georgia referred close contacts to an app that provided tailored educational videos about vaccines along with a small pharmacy-based financial incentive for vaccine receipt. The primary objective of this study was to determine the feasibility of implementing this app-based cocooning intervention. RESULTS Two hundred seventy seven contacts were enrolled in this study. Of those who received the educational videos, 96% found them interesting, 100% found them clear to understand, 97% found them helpful, and 99% trusted them. Completion of the videos led to significant increases in influenza vaccine knowledge (p = 0.025), Tdap vaccine knowledge (p < 0.001), and intention to receive these vaccines (p = 0.046). Of the 136 participants who reported receiving influenza vaccine, 41 (30%) reported receiving it at a pharmacy, and of the 66 who reported receiving Tdap vaccine, 15 (23%) reported receiving it at a pharmacy. Of all participants, 80% reported being comfortable receiving vaccines at a pharmacy instead of a doctor's office. The provision of small pharmacy-based financial incentives combined with individually-tailored educational videos about vaccines led to 6.97 (95%CI: 2.25-21.64) times higher odds of self-reported receipt of influenza vaccine than providing small pharmacy-based financial incentives without these videos. No significant difference was found for Tdap vaccine. CONCLUSIONS Tailored vaccine education can positively impact vaccine knowledge and intentions among adults. An app-based referral program providing education and financial incentives for cocooning vaccination at pharmacies is feasible.

Abstract
INTRODUCTION Vaccination against influenza and pertussis in pregnancy offers a 'two-for-one' opportunity to protect mother and child. Pregnant patients have increased risk of severe disease from influenza and newborns have increased risk of severe disease from both influenza and pertussis. Obstetricians need communication tools to support their self-efficacy and effectiveness in communicating the importance of immunisation during pregnancy and ultimately improving maternal vaccination rates. METHODS AND ANALYSIS We describe the protocol for a pragmatic study testing the feasibility and potential impact of a clinician communication strategy on maternal vaccination uptake. This study will be conducted in five prenatal care settings in Colorado, USA. The Motivational Interviewing for Maternal Immunisation strategy involves training prenatal care providers to use motivational interviewing in the vaccine conversation with pregnant patients. Our primary outcomes will be the adoption and implementation of the intervention measured using the Enhanced RE-AIM/Practical Robust Implementation and Sustainability Model for dissemination and implementation. Secondary outcomes will include provider time spent, fidelity to Motivational Interviewing and self-efficacy measured through audio recorded visits and provider surveys, patients' visit experience based on audio recorded visits and follow-up interviews, and maternal vaccine uptake as measured through chart reviews. ETHICS AND DISSEMINATION This study is approved by the following institutional review boards: Colorado Multiple Institutional Review Board. Results will be disseminated through peer-reviewed manuscripts and conference presentations. TRIAL REGISTRATION NUMBER NCT04302675.

Abstract
PURPOSE OF REVIEW To offer healthcare providers current, evidence-based approaches for addressing vaccine hesitancy to increase vaccine coverage and reduce the frequency of vaccine-preventable disease outbreaks. RECENT FINDINGS Vaccine hesitancy is a growing problem with profound societal, economic, and medical consequences. Understanding the complexity of vaccine hesitancy can inform approaches to increasing vaccine uptake on both the individual and population levels. Notably, pediatricians play a critical role in increasing vaccine uptake due to their relationships with families. This doctor-patient relationship establishes trust and allows evidence-based intervention strategies to be effective in the office. Understanding potential solutions outside the office, such as media campaigns and policy changes, also provide insight into vaccine hesitancy and potential directions for future research. While pediatricians' attempts in the clinic to increase coverage remain crucial, vaccine hesitancy remains a formidable public health problem that requires attention on both the micro and macro levels to be addressed successfully. SUMMARY Providers have an opportunity to increase both confidence in and uptake of vaccines. Public health interventions would effectively complement strategies in the clinic to increase overall coverage.

Impact of media reports regarding influenza vaccine on obstetricians' vaccination practices. Vaccine 2020; 38:3474-3479. [PMID: 32204941 PMCID: PMC9987339 DOI: 10.1016/j.vaccine.2020.02.051] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 02/14/2020] [Accepted: 02/18/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND In 2017, three media stories regarding influenza vaccine may have impacted obstetricians' (OB) influenza vaccination practices: reports of reduced influenza vaccine effectiveness, a severe influenza season, and a possible increased risk of miscarriage among pregnant women receiving 2009 H1N1 vaccine in the 1st trimester who had received H1N1 vaccine the previous season (later disproven). OBJECTIVE Describe OB's: (1) awareness of; (2) attitudes and experiences related to; and (3) reported alterations in practice as a result of these reports. METHODS A survey among a nationally representative sample of OBs April to June 2018. RESULTS Response rate was 65% (302/468). 88% of OBs were "very aware" of the severe season, 74% of lower effectiveness, and 25% of the miscarriage study (47% "completely unaware" of miscarriage study). Among those aware, 58%, 57%, and 16% reported ≥10% of pregnant patients initiated discussions about the severe season, lower effectiveness, and miscarriage study, respectively. Most (83%) agreed reports about increased severity increased their enthusiasm for recommending influenza vaccine; fewer agreed reports about the miscarriage study (18%) and lower vaccine effectiveness (12%) decreased their enthusiasm for recommending influenza vaccine. Providers were more likely to initiate discussion with patients about increased severity of the season than the other reports. However, 35% agreed the miscarriage study reports increased their concerns about influenza vaccine safety; 18% (n = 48) reported changing the way they recommended influenza vaccine. Of those, 17 (6% of all respondents) reported not recommending influenza vaccine to women during the 1st trimester and 26 (10% of all respondents) recommended it but were willing to delay until the 2nd trimester. CONCLUSIONS During a season in which media stories could have influenced OB influenza vaccination behaviors in different directions, reports underscoring importance of influenza vaccine may have had more impact on OBs' recommendations than reports questioning vaccine safety or effectiveness.

Abstract
BACKGROUND Infants too young to be fully vaccinated are vulnerable to potentially deadly influenza and pertussis infections. The cocooning strategy limits this risk by vaccinating those likely to interact with the infant and mother during this vulnerable time, such as close friends and family members. Distribution of accurate and accessible vaccine information through existing social networks could be an important tool in increasing vaccine confidence and coverage. METHODS We surveyed 1095 pregnant women from diverse prenatal care practices in Georgia and Colorado. These women were surveyed through a mobile app to assess vaccine intentions, attitudes, beliefs, norms, and levels of trust, and then presented brief individually-tailored educational videos about maternal and infant vaccines and the cocooning strategy. They were then given the opportunity to refer up to six contacts to enroll in the app and receive similar vaccine education. RESULTS Twenty-eight percent of these women referred at least one contact, with an average of 2.67 contacts per referring woman. Most referrals (93%) were partners, parents, siblings, relatives, or close friends. Attitudinal constructs significantly associated with increased likelihood of referring contacts included: intention to receive maternal influenza vaccine, perceived safety of maternal Tdap vaccine, perceived efficacy of maternal influenza vaccine, perceived susceptibility to and severity of influenza during pregnancy, and trust in vaccine information from the Centers for Disease Control and Prevention (CDC) and academic institutions. Uncertainty about infant vaccine intentions was associated with decreased likelihood of referring contacts. CONCLUSIONS Pregnant women who valued vaccination and trusted vaccine information from academic institutions were more likely to refer an educational app about vaccines than those who did not. Further research is needed to determine the potential impact of this strategy on vaccine coverage when implemented on a large scale.

Abstract
OBJECTIVE To describe 1) obstetrician-gynecologists' (ob-gyns') perceptions of the frequency of vaccine refusal among pregnant patients and perceived reasons for refusal and 2) ob-gyns' strategies used when encountering vaccine refusal and perceived effectiveness of those strategies. METHODS We conducted an email and mail survey among a nationally representative network of ob-gyns from March 2016 to June 2016. RESULTS The response rate was 69% (331/477). Health care providers perceived that pregnant women more commonly refused influenza vaccine than tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine: 62% of respondents reported 10% or greater of pregnant women they care for in a typical month refused influenza vaccine compared with 32% reporting this for Tdap vaccine. The most commonly reported reasons for vaccine refusal were patients' belief that influenza vaccine makes them sick (48%), belief they are unlikely to get a vaccine-preventable disease (38%), general worries about vaccines (32%), desire to maintain a natural pregnancy (31%), and concern that their child could develop autism as a result of maternal vaccination (25%). The most commonly reported strategies ob-gyns used to address refusal were stating that it is safe to receive vaccines in pregnancy (96%), explaining that not getting the vaccine puts the fetus or newborn at risk (90%), or that not getting the vaccine puts the pregnant woman's health at risk (84%). The strategy perceived as most effective was stating that not getting vaccinated puts the fetus or newborn at risk. CONCLUSION Ob-gyns perceive vaccine refusal among pregnant women as common and refusal of influenza vaccine as more common than refusal of Tdap vaccine. Emphasizing the risk of disease to the fetus or newborn may be an effective strategy to increase vaccine uptake.

Abstract
INTRODUCTION Tetanus, diphtheria, and acellular pertussis (Tdap) and influenza vaccines are recommended for pregnant women in each pregnancy, yet uptake is suboptimal. This study tested the efficacy of an online vaccine resource in increasing uptake of Tdap and influenza vaccines among pregnant women. STUDY DESIGN RCT. SETTING/PARTICIPANTS This study was conducted among women in the third trimester of pregnancy in an integrated healthcare system in Colorado in September 2013-July 2016, with data analysis in 2017-2018. INTERVENTION Women were randomly assigned to 1 of 3 arms: website with vaccine information and interactive social media components, website with vaccine information only, or usual care. Participants in the website with vaccine information and interactive social media components and website with vaccine information only arms had access to the same base vaccine content. The website with vaccine information and interactive social media components also included a blog, discussion forum, and "Ask a Question" portal. MAIN OUTCOME MEASURES Tdap and influenza vaccination. These outcomes were analyzed separately. RESULTS For influenza (n=289), women in both the website with vaccine information and interactive social media components (OR=2.19, 95% CI=1.06, 4.53) and website with vaccine information only (OR=2.20, 95% CI=1.03, 4.69) arms had higher vaccine uptake than the usual care arm. The proportions of women receiving the influenza vaccine were 57%, 55%, and 36% in the website with vaccine information and interactive social media components, website with vaccine information only, and usual care arms, respectively. For Tdap (n=173), there were no significant differences in vaccine uptake between study arms. The proportions of women receiving Tdap were 71%, 69%, and 68% in the website with vaccine information and interactive social media components, website with vaccine information only, and usual care arms, respectively. CONCLUSIONS Web-based vaccination information sent to pregnant women can positively influence maternal influenza vaccine uptake. Because of potential scalability, the impact of robust vaccination information websites should be studied in other settings.

Abstract
Pertussis vaccination of parents and household contacts (‘cocooning’) to protect newborn infants is an established strategy in many countries, although uptake may be low. Many aspects may influence such decision-making. We conducted a cross-sectional survey (NCT01890447) of households and other close contacts of newborns aged ≤6 months (or of expectant mothers in their last trimester) in Spain and Italy, using an adaptive discrete-choice experiment questionnaire. Aims were to assess the relative importance of attributes influencing vaccine adoption, and to estimate variation in vaccine adoption rates and the impact of cost on vaccination rates. Six hundred and fifteen participants (Spain, n = 313; Italy, n = 302) completed the survey. Of 144 available questionnaire scenarios, the most frequently selected (14% of respondents in both countries) were infant protection by household vaccination at vaccination center, recommendation by family physician and health authorities, with information available on leaflets and websites. The attribute with highest median relative importance was ‘reduction in source of infection’ in Spain (23.1%) and ‘vaccination location’ in Italy (18.8%). Differences between other attributes were low in both countries, with media attributes showing low importance. Over 80% of respondents indicated a definite or probable response to vaccine adoption (at no-cost) with estimated probability of adoption of 89–98%; applying vaccine costs (25€ per person) would reduce the probability of uptake by 7–20% in definite/probable respondents. Awareness of these determinants is helpful in informing Health Authorities and healthcare practitioners implementing a cocooning strategy for those populations where maternal immunization is not a preferred option.

Abstract
BACKGROUND The Advisory Committee for Immunization Practices recommends that all pregnant women receive the seasonal influenza vaccine and the tetanus toxoid, diphtheria toxoid, and acellular pertussis (Tdap) vaccine during every pregnancy. However, vaccination coverage rates are suboptimal among pregnant women in the United States, leaving these women and their unborn children at risk of vaccine-preventable diseases and their complications. OBJECTIVES We sought to understand the current landscape of published literature regarding maternal immunization, including barriers to and predictors of vaccine acceptance, and identify gaps in the research in order to inform strategies for future programmatic improvement. METHODS We conducted a literature search using MEDLINE (OVID), PsychINFO, and CINAHL (Ebsco) databases. The search included published, English-language manuscripts that identified patient, provider, or system-level barriers to, predictors of, or interventions that improved uptake of maternal vaccines among pregnant women in the US. Studies were reviewed using an inductive thematic analysis approach. RESULTS We included 75 studies in our review. Pregnant women identified 25 different barriers to accepting recommended maternal immunizations; barriers related to vaccine safety perceptions were the most common. Healthcare providers identified 24 different barriers to vaccinating their pregnant patients. The most commonly cited barriers among healthcare providers were financial concerns. Eighteen different predictors of vaccine acceptance were identified. Receipt of a healthcare provider's recommendation was the factor most frequently reported as a reason for vaccination among pregnant women. CONCLUSIONS We were able to identify gaps in the literature regarding maternal immunization and make recommendations for future research. Efforts to address the challenges of maternal immunization in the United States should include increasing the focus on Tdap, implementing more high-level assessments of safety perceptions and associated concerns, and determining most effective interventions.

Abstract
OBJECTIVE Several states require schools and child cares to report vaccination rates, yet little is known about the impact of these policies. Our objectives were to assess: (1) predicted impact of vaccination rates on school/child care choice, (2) differences between vaccine hesitant and non-hesitant parents, and (3) differences by child's age. METHODS In 2016, a cross-sectional email survey of Colorado mothers with children ≤12 years old assessed value of vaccination rates in the context of school/child care choice. A willingness-to-pay framework measured preference for schools/child cares with different vaccination rates using tradeoff with commute time. RESULTS Response rate was 42% (679/1630). Twelve percent of respondents were vaccine hesitant. On a scale where 1 is "not important at all" and 4 is "very important" parents rated the importance of vaccination rates at 3.08. Respondents (including vaccine-hesitant respondents) would accept longer commutes to avoid schools/child cares with lower vaccination rates. Parents of child-care-age children were more likely to consider vaccination rates important. CONCLUSIONS This study shows parents highly value vaccination rates in the context of school and child care choice. Both hesitant and non-hesitant parents are willing to accept longer commute times to protect their children from vaccine-preventable diseases.

Abstract
AbstractSocial contact between individuals is believed to be a fundamental cause in the transmission of many respiratory tract infections. Because they have not yet been fully vaccinated, infants are at high risk for contracting whooping cough, influenza and their serious complications. Therefore, determining infant social contact patterns is an important step in protecting them from respiratory tract infection. This study included 1200 healthy infants (<12 months of age). Social contact diaries were used to estimate the frequency and nature of the infants’ social contacts. This survey also gathered information regarding the infants’ respiratory symptoms and their frequency of attendance at crowded places over a period of 1 week. The diary return rate was 83.8% (N = 1006), and there was a total of 4706 contacts reported for these infants. The median daily contact number per capita was 4 (range 1–18). The median number of contacts with adolescents was 0 (range 0–7). Of the infants, 50.3% had contact with non-household individuals. The mothers had the longest contacts with their babies. Contacts with school children, frequency of attendance at crowded places and age were determined to be significant effective factors for reporting respiratory symptoms. Results suggest that school-age siblings and the mothers should be primarily vaccinated, and parents should keep their babies away from crowded places for protecting their infants.

Immunization Practices of U.S. Obstetrician/Gynecologists for Pregnant Patients. Am J Prev Med 2018; 54:205-213. [PMID: 29246674 PMCID: PMC5783738 DOI: 10.1016/j.amepre.2017.10.016] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2017] [Revised: 09/14/2017] [Accepted: 10/20/2017] [Indexed: 11/26/2022]
Abstract
INTRODUCTION U.S. obstetrician/gynecologists play a critical role as vaccinators of pregnant women. However, little is known about their current immunization practices. Thus, study objectives were to determine (1) practices related to assessment of vaccination status and vaccine delivery for pregnant patients; (2) barriers to stocking and administering vaccines; and (3) factors associated with administering both influenza and tetanus, diphtheria, and acellular pertussis (Tdap) vaccines. METHODS An e-mail and mail survey among a national sample of obstetrician/gynecologists conducted July-October 2015 (analysis August 2016-August 2017). RESULTS The response rate was 73.2% (353/482). Among obstetrician/gynecologists caring for pregnant women (n=324), vaccination status was most commonly assessed for influenza (97%), Tdap (92%), and measles, mumps, and rubella vaccines (88%). Vaccines most commonly administered included influenza (85%) and Tdap (76%). Few respondents reported administering other vaccines to pregnant patients. More physicians reported using standing orders for influenza (66%) than Tdap (39%). Other evidence-based strategies for increasing vaccine uptake were less frequently used (electronic decision support, 42%; immunization information system to record [13%] or assess vaccination status [11%]; reminder/recall, 7%). Barriers most commonly reported were provider financial barriers, yet provider attitudinal barriers were rare. Providers who administered both influenza and Tdap vaccines were more likely to be female, perceive fewer financial and practice barriers, less likely to be in private practice, and perceive more patient barriers. CONCLUSIONS Although most obstetrician/gynecologists administer some vaccines to pregnant women, the focus remains on influenza and Tdap. Financial barriers and infrequent use of evidence-based strategies for increasing vaccination uptake may be hindering delivery of a broader complement of adult vaccines in obstetrician/gynecologist offices.

Measles, the media, and MMR: Impact of the 2014-15 measles outbreak. Vaccine 2016; 34:6375-6380. [PMID: 27817962 DOI: 10.1016/j.vaccine.2016.10.048] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 10/13/2016] [Accepted: 10/14/2016] [Indexed: 11/22/2022]
Abstract
OBJECTIVE In late 2014, a measles outbreak beginning in California received significant media attention. To better understand the impact of this outbreak, we conducted a survey to assess and compare among vaccine hesitant and non-hesitant new mothers how this outbreak affected vaccine knowledge, attitudes, vaccination plans, and media use. METHODS A cross-sectional email survey of English-speaking women with a child ⩽1year old using a convenience sample of women from nine obstetrics and gynecology (OB/GYN) practices in Colorado assessed vaccine hesitancy, knowledge and attitudes about MMR vaccines and the outbreak, MMR vaccination plans before and after the outbreak, and use of and trust for media sources related to the outbreak. RESULTS The response rate was 50% (351/701). Knowledge about the outbreak was high and vaccination attitudes were mostly favorable. Forty-eight percent of respondents thought MMR vaccine was more important after the outbreak. Online news (76%), television news (75%), and social media (68%) were the most frequently used media sources, yet were highly trusted by only 18%, 22%, and 1% of respondents respectively. Government websites (34%) and information from a doctor's office (34%) were infrequently used, but were highly trusted by 62% and 60% of respondents. Knowledge of the outbreak was lower among vaccine-hesitant respondents. Few mothers changed MMR vaccination plans after the outbreak. CONCLUSIONS New mothers had high levels of knowledge and favorable attitudes about vaccination after the 2014-15 measles outbreak. Media sources used the most are not the most trusted. Communication about outbreaks of vaccine-preventable diseases should include spread of accurate information to new media sources and strengthening of existing trust in traditional media.

Assessing determinants of the intention to accept a pertussis cocooning vaccination: A survey among Dutch parents. Vaccine 2016; 34:4744-4751. [PMID: 27523741 DOI: 10.1016/j.vaccine.2016.07.024] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2016] [Revised: 07/08/2016] [Accepted: 07/14/2016] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Pertussis cocooning is one of the strategies aiming to prevent the potential harm of pertussis in infants by vaccinating (among others) their parents. Several countries adopted this strategy, but uptake is a problem. Determinants of parental uptake are important in the design of an effective vaccination programme. Therefore, this study aims to assess parents' intention to accept a pertussis cocooning vaccination and its determinants. METHODS A 98 item questionnaire was developed based on a theoretical framework, assessing parents' intention to accept a pertussis cocooning vaccination and its personal and psychosocial determinants. In addition, beliefs underlying parents' attitude towards pertussis cocooning vaccination were assessed. Both logistic and linear regression analysis were used to assess univariate and multivariate associations amongst study variables. RESULTS Parents returned 282 questionnaires. The majority of the parents (78%) reported a positive intention to accept a pertussis cocooning vaccination. Attitude (OR 6.6, p<.001), anticipated negative affect in response to non acceptance (OR 1.65, p<.001), anticipated negative affect in response to acceptance (OR 0.55, p .040) and decisional uncertainty (OR 0.52, p .002) were significantly associated with intention. General vaccination beliefs (β 0.58, p<.001), moral norm (β 0.22, p<.001), perceived susceptibility of pertussis in children (β 0.10, p.004), and efficacy outcome expectations (β 0.15, p.011) were significant correlates of attitude towards pertussis cocooning vaccination. CONCLUSION The parental intention to accept a pertussis cocooning vaccination in this study is rather high. Targeting the identified determinants of parents' acceptance in a pertussis cocooning vaccination programme is crucial to secure that intention is translated into actual vaccination uptake.

Abstract
Context Several countries have reported a resurgence of pertussis in the last decades. This puts infants (especially <6 months) at risk of severe complications, because they are too young to be fully protected by vaccination. The global pertussis initiative has proposed pertussis vaccination of young infants’ close contacts, in order to reduce pertussis transmission and the burden of the disease on infants. Our aim is to explore the perceived determinants (barriers and facilitators) of intention to accept vaccination among the possible target groups of pertussis vaccination for cocooning. Consideration of these determinants is necessary to optimise the uptake of the vaccination. Methods We conducted 13 focus groups and six individual semi-structured interviews with members of possible target groups for pertussis cocooning (i.e. parents, maternity assistants, midwives, and paediatric nurses) in the Netherlands. Here, both maternal pertussis vaccination as well as pertussis cocooning has not been implemented. The topic list was based on a literature review and a barrier framework. All interviews were transcribed verbatim and two researchers performed thematic content analysis. Findings The participants’ risk perception, outcome expectations, general vaccination beliefs, moral norms, opinion of others, perceived autonomy, anticipated regret, decisional uncertainty, and perceived organisational barriers were all factors that influenced the intention to accept pertussis vaccination for cocooning. Discussion This study has identified nine perceived determinants that influence the intention to accept pertussis cocooning vaccination. We add the following determinants to the literature: perceived cost-effectiveness (as a concept of outcome expectations), justice (as a concept of moral norms), anticipated regret, and decisional uncertainty. We recommend considering these determinants in vaccination programmes for pertussis cocooning vaccination. Experience, information and trust emerged as predominant themes within these determinants. These themes require particular attention in future research on vaccination acceptance, especially with regard to their role in use and implementation in policy and practice.
