Behavioral interventions for vaccination uptake: A systematic review and meta-analysis. Health Policy 2023; 137:104894. [PMID: 37714082 PMCID: PMC10885629 DOI: 10.1016/j.healthpol.2023.104894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 06/22/2023] [Accepted: 08/15/2023] [Indexed: 09/17/2023]
Abstract
BACKGROUND Human behavior and more specifically behavioral insight-based approaches to vaccine uptake have often been overlooked. While there have been a few narrative reviews indexed in Medline on behavioral interventions to increase vaccine uptake, to our knowledge, none have been systematic reviews and meta-analyses covering not just high but also low-and-middle income countries. METHODS We included 613 studies from the Medline database in our systematic review and meta-analysis categorizing different behavioral interventions in 9 domains: education campaigns, on-site vaccination, incentives, free vaccination, institutional recommendation, provider recommendation, reminder and recall, message framing, and vaccine champion. Additionally, considering that there is variability in the acceptance of vaccines among different populations, we assessed studies from both high-income countries (HICs) and low- to middle-income countries (LMICs), separately. FINDINGS Our results showed that behavioral interventions can considerably improve vaccine uptake in most settings. All domains that we examined improved vaccine uptake with the highest effect size associated with provider recommendation (OR: 3.4 (95%CI: 2.5-4.6); Domain: motivation) and on-site vaccination (OR: 2.9 (95%CI: 2.3-3.7); Domain: practical issues). While the number of studies conducted in LMICs was smaller, the quality of studies was similar with those conducted in HICs. Nevertheless, there were variations in the observed effect sizes. INTERPRETATION Our findings indicate that "provider recommendation" and "on-site vaccination" along with other behavioral interventions can be employed to increase vaccination rates globally.

Ekezie W, Connor A, Gibson E, Khunti K, Kamal A. A Systematic Review of Behaviour Change Techniques within Interventions to Increase Vaccine Uptake among Ethnic Minority Populations. Vaccines (Basel) 2023; 11:1259. [PMID: 37515074 PMCID: PMC10386142 DOI: 10.3390/vaccines11071259] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 07/11/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023] Open
Abstract
COVID-19 caused significant morbidity and mortality amongst ethnic minority groups, but vaccine uptake remained lower than non-minoritised groups. Interventions to increase vaccine uptake among ethnic minority communities are crucial. This systematic review synthesises and evaluates behaviour change techniques (BCTs) in interventions to increase vaccination uptake in ethnic minority populations. We searched five databases and grey literature sources. From 7637 records identified, 23 studies were included in the review. Interventions were categorised using the Behaviour Change Wheel (BCW) and Behaviour Change Taxonomy v1. Vaccines included influenza, pertussis, tetanus, diphtheria, meningitis and hepatitis. Interventions were primarily delivered in health centres/clinics and community settings. Six BCW intervention functions and policy categories and 26 BCTs were identified. The main intervention functions used were education, persuasion and enablement. Overall, effective interventions had multi-components and were tailored to specific populations. No strong evidence was observed to recommend specific interventions, but raising awareness and involvement of community organisations was associated with positive effects. Several strategies are used to increase vaccine uptake among ethnic minority communities; however, these do not address all issues related to low vaccine acceptance. There is a strong need for an increased understanding of addressing vaccine hesitancy among ethnic minority groups.

Abstract
The COVID-19 pandemic has imposed many communication challenges for public health authorities, especially communicating the safety, effectiveness, and importance of the COVID-19 vaccine. This study takes an integrative approach that includes a content analysis of COVID-19 vaccine-related messages from the CDC Facebook page and an experimental test of the effectiveness of the same types of vaccine-related messages on participants' attitudes toward the COVID-19 vaccine. Our findings from the content analysis show that gain-frame was used significantly more than loss-frame, and statistical evidence was more prevalent than narrative evidence in the CDC's COVID-19 vaccine-related messaging. Results from the experiment indicated that loss-framed, and messages with statistical evidence, may be more successful in promoting positive attitudes toward the COVID-19 vaccine.

Differences and disparities in seasonal influenza vaccine, acceptance, adverse reactions, and coverage by age, sex, gender, and race. Vaccine 2022; 40:1643-1654. [PMID: 33933316 PMCID: PMC8551304 DOI: 10.1016/j.vaccine.2021.04.013] [Citation(s) in RCA: 32] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 03/27/2021] [Accepted: 04/06/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Influenza is a significant threat to public health worldwide. Despite the widespread availability of effective and generally safe vaccines, the acceptance and coverage of influenza vaccines are significantly lower than recommended. Sociodemographic variables are known to be potential predictors of differential influenza vaccine uptake and outcomes. OBJECTIVES This review aims to (1) identify how sociodemographic characteristics such as age, sex, gender, and race may influence seasonal influenza vaccine acceptance and coverage; and (2) evaluate the role of these sociodemographic characteristics in differential adverse reactions among vaccinated individuals. METHODS PubMed was used as the database to search for published literature in three thematic areas related to the seasonal influenza vaccine - vaccine acceptance, adverse reactions, and vaccine coverage. RESULTS A total of 3249 articles published between 2010 and 2020 were screened and reviewed, of which 39 studies were included in this literature review. By the three thematic areas, 17 studies assessed vaccine acceptance, 8 studies focused on adverse reactions, and 14 examined coverage of the seasonal influenza vaccine. There were also two studies that focused on more than one of the areas of interest. CONCLUSION Each of the four sociodemographic predictors - age, sex, race, and gender - were found to significantly influence vaccine acceptance, receipt and outcomes in this review.

Abstract
Background Pregnant women are at increased risk of complications from flu, but uptake of
flu vaccination is below 75% targets. Evidence suggests that changing
illness risk appraisals may increase vaccination behaviour. In 2018–2019,
researchers, public health specialists, and pregnant women co-designed a
short animation targeting (unhelpful) beliefs underlying pregnant women’s
flu risk appraisals aiming to promote vaccination uptake. Aims This study aimed to examine effectiveness of a digital intervention
(animation) in increasing flu vaccination among pregnant women through
changing illness risk appraisals. Method A prospective study design was used, involving convenience sampling of
unvaccinated pregnant women recruited via a Qualtrics Online Panel.
Participants received small payments via the panel for survey completion.
Risk appraisals and intention to vaccinate were measured at baseline and
immediately after intervention presentation (follow-up one). Six months
later, a further survey (follow-up two) was administered measuring
vaccination behaviour. Results Baseline and first follow-up surveys were completed by 411 participants.
Watching the animation led to increased appraisals of likelihood of getting
flu while pregnant and severity of flu during pregnancy, and increased
intentions to accept flu vaccination during pregnancy. Of the 67 respondents
who completed follow-up survey two, 38 reported having the vaccination while
pregnant. Conclusions This study provides evidence supporting the promise of the intervention.
Randomized controlled trials are required to produce definitive efficacy
evidence. Should such a study prove intervention effectiveness, it could be
readily embedded within existing campaigns at national and local levels by
public health organizations.

Abstract
Background Growing evidence shows that many parents begin the decision-making process about infant vaccination during pregnancy and these decisions – once established – may be resistant to change. Despite this, many interventions targeting vaccination are focused on communicating with parents after their baby is born. This suggests that the prenatal period may constitute a missed opportunity for communicating with expectant parents about infant vaccination. Methods Using a longitudinal qualitative design, we conducted two interviews (prepartum and postpartum) with women (n = 19) to explore the optimal timing of vaccination information. The data were analyzed thematically, and examined across all sets of pre- and post-partum interviews as well as within each individual participant to draw out salient themes. Results Most participants formed their intentions to vaccinate before the baby was born and indicated that they would welcome information about vaccination from their maternity care providers. However, few individuals recalled their maternity care providers initiating vaccination-related conversations with them. Conclusion The prenatal period is an important time to begin conversations with expectant parents about vaccinating their infants, particularly if these conversations are initiated by trusted maternity care providers. More information is needed on how maternity care providers can be better supported to have these conversations with their patients.

Abstract
BACKGROUND Maternal attitudes and beliefs have been shown to influence childhood vaccination coverage, resulting in under-vaccination, non-vaccination, and vaccination delay. This study aimed to investigate the mothers' attitudes and perceptions about vaccination for their children in Greece. METHODS This was an online cross-sectional study, conducted from 4 April to 8 June 2020. A self-administered questionnaire was used to collect information about mothers' and their children's socio-demographic characteristics, previous vaccination behavior, and mothers' attitudes and perceptions about childhood vaccination. Participants included adult mothers with at least one minor child. RESULTS One thousand eight hundred eighty-five mothers participated, with the majority (91.7%) believing in the usefulness of vaccines and that vaccines protect children from serious and life-threatening diseases. A larger percentage of mothers with higher educational attainment agreed/absolutely agreed that all vaccinations provided by the National Vaccination Program must be offered to their children (91.6%) (p = 0.02) and that vaccines protect children from serious and life-threatening diseases (92.9%) (p = 0.01). Significant more married/in cohabitation and not single-parent mothers agreed that vaccines are safe (53.5% and 53.4%, respectively). There were also several significant associations between maternal attitudes toward childhood vaccination and previous maternal vaccination practices [(e.g., adherence to recommended vaccination dosages (all p-values < 0.01), vaccination delays (all p-values < 0.05), and vaccination during pregnancy (all p-values < 0.01)]. CONCLUSION Maternal attitudes and perceptions toward childhood vaccination are significantly influenced by sociodemographic factors and maternal vaccination practices. Revealing those is essential for public health officials in developing future strategies to improve childhood vaccination coverage and acceptance of new vaccines such as the COVID-19 vaccine.

Racial disparities in influenza immunization during pregnancy in the United States: A narrative review of the evidence for disparities and potential interventions. Vaccine 2021; 39:4938-4948. [PMID: 34312009 DOI: 10.1016/j.vaccine.2021.07.028] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/09/2021] [Accepted: 07/12/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The objectives of this review were to summarize existing data on racial disparities in maternal immunization for influenza in the U.S. and to review the literature on interventions to improve the uptake of the influenza vaccine among Black pregnant women. DATA SOURCES U.S. survey data on maternal influenza immunization by racial and ethnic group were summarized in narrative form. To review intervention studies, PubMed, CINAHL, EMBASE, and the Cochrane Library databases were searched for English language articles published 2017 to 2021, in addition to studies identified by a previous systematic review. STUDY ELIGIBILITY CRITERIA Peer-reviewed studies conducted in the U.S. and reporting interventions designed to increase the uptake of the influenza vaccine in pregnancy with study populations including at least 20% of participants identifying as Black were included. STUDY APPRAISAL AND SYNTHESIS METHODS Studies were grouped and reviewed in a narrative manner according to whether they were conducted in predominantly Black populations or in more racially diverse populations, and whether they tested multicomponent or single-component interventions. RESULTS A decade of survey data show that Black women in the U.S. consistently have the lowest rate of influenza immunization in pregnancy. Black women report a lower rate of being recommended or offered the vaccine, and provider recommendation is associated with greater vaccine uptake. Intervention studies to increase influenza immunization among Black pregnant women have reported mixed results. Successful interventions include multicomponent practice-based interventions, group prenatal care, and culturally competent patient educational messages. CONCLUSIONS Racial disparities in maternal uptake of the influenza vaccine are long-standing, but not intractable. More research is needed to test interventions to address this disparity, with a focus on increasing provider recommendation and offer of the vaccine, addressing patients' concerns about vaccine safety and efficacy, improving providers' cultural competence, and building trust between providers and patients.

Abstract
BACKGROUND Flu can have serious consequences for pregnant woman and unborn babies. Vaccination provides safe and effective protection, yet uptake among pregnant women is below national targets. Digital interventions are effective at increasing adherence to health interventions. AIMS This review aimed to establish whether digital interventions are effective at increasing rates of flu vaccination among pregnant women, and to determine the overall effect size. METHOD Systematic searches identified digital intervention trials, aiming to increase rate of flu vaccination among pregnant women. Random-effects meta-analysis provided a combined effect size and examined which mode of digital interventions had the largest effects on flu vaccination. RESULTS Ten studies were included in the review. The majority of digital interventions were more effective at increasing rates of flu vaccination (7-81.3% uptake) than usual care or non-digital interventions (7.3-47.1% uptake). When meta-analysed, digital interventions had a small, non-significant effect (odds ratio [OR] = 1.29, 95% confidence interval [CI]: 0.71, 2.31), P = 0.40. Text messages (OR = 1.25, 95% CI: 0.58, 2.67), P = 0.57 appeared less effective than other digital interventions (OR = 1.58, 95% CI: 1.02, 2.46), P = 0.04. CONCLUSIONS Overall, there is a lack of high-quality studies reporting the effectiveness of digital interventions at increasing flu vaccination during pregnancy. Future interventions may benefit from using video or social media to communicate messages for maximum success in targeting an increase in rates of flu vaccination in pregnancy.

Abstract
Objective Pregnant women and unborn babies are at increased risk of complications from influenza, including pneumonia, yet in the UK, uptake of flu vaccination amongst this population remains <50%. Pregnant women hold beliefs about risks of flu and efficacy of vaccination that consistently predict them to decline vaccination. This study aimed to develop a theory and evidence-based intervention addressing these beliefs to promote flu vaccine uptake. Methods The intervention was developed by behavioural scientists, pregnant women, midwives, clinicians and Public Health professionals, informed by Intervention Mapping. Six predefined steps were performed in line with Intervention Mapping. Results The intervention is an animation addressing beliefs about risks of flu and efficacy of vaccination. Preliminary testing using qualitative methodology indicates the information within the animation is appropriate, and the animation is acceptable to pregnant women. Conclusions This is the first known intervention for pregnant women, aiming to increase flu vaccination through addressing risk and efficacy appraisals. It has been implemented within seasonal flu vaccination campaigns during 2018/19 and 2019/20 within one geographically and ethnically diverse area of the UK.

Abstract
BACKGROUND Pregnant women and their unborn babies are at increased risk of complications as a result of flu, yet uptake of the flu vaccination in the UK remains low. Digital interventions have proven effectiveness in changing health behaviour, but their effectiveness in increasing flu vaccination amongst pregnant women has not been examined. This protocol details the design and methodology of a systematic review and meta-analysis, examining the effectiveness of digital interventions in increasing flu vaccination amongst pregnant women. METHODS Bibliographic databases will be searched using appropriate search terms related to vaccination, pregnancy and flu. Randomised, non-randomised, quasi randomised controlled trials and other quantitative study designs will be eligible for inclusion, and studies will present the rate of flu vaccination amongst pregnant women of digital interventions compared to non-digital interventions, or usual care. No date or study country restrictions will be put on included studies, but studies will be published in English. DISCUSSION This is the first known systematic review to examine the effectiveness of digital interventions in increasing the rate of flu vaccination amongst pregnant women. This review has the potential to inform whether digital interventions are an appropriate and successful method of increasing flu vaccination amongst pregnant women, and to determine which mode of digital intervention is most effective. TRIAL REGISTRATION This systematic review is registered on the international prospective register of systematic reviews (PROSPERO). Registration number pending.

Abstract
Purpose There is good evidence that for many behaviours, increasing risk appraisal can lead to a change in behaviour, heightened when efficacy appraisals are also increased. The present systematic review addressed whether interventions presenting a risk message increase risk appraisal and an increase in vaccination intentions and uptake. Method A systematic search identified randomized controlled trials of interventions presenting a risk message and measuring risk appraisal and intentions and uptake post‐intervention. Random‐effects meta‐analyses investigated the size of the effect that interventions had on vaccination risk appraisal and on vaccination behaviour or intention to vaccinate, and the size of the relationship between vaccination risk appraisal and vaccination intentions and uptake. Results Eighteen studies were included and 16 meta‐analysed. Interventions overall had small significant effects on risk appraisal (d = 0.161, p = .047) and perceptions of susceptibility (d = 0.195, p = .025), but no effect on perceptions of severity (d = −0.036, p = .828). Interventions showed no effect on intention to vaccinate (d = 0.138, p = .195) and no effect on vaccination behaviour (d = 0.043, p = .826). Interventions typically did not include many behaviour change techniques (BCTs), with the most common BCT unique to intervention conditions being ‘Information about Health Consequences’. Few of the included studies attempted to, or successfully increased, efficacy appraisals. Conclusions Overall, there is a lack of good‐quality primary studies, and existing interventions are suboptimal. The inclusion of additional BCTs, including those to target efficacy appraisals, could increase intervention effectiveness. The protocol (CRD42015029365) is available from http://www.crd.york.ac.uk/PROSPERO/. Statement of contribution What is already known on this subject? Previous research indicates that an increase in risk appraisal is associated with increased uptake in health‐related behaviours. Research suggests that interventions increasing risk appraisal have a greater effect on intention when elements of efficacy appraisals are simultaneously increased. What does this study add? This is the first systematic review to examine the effect of interventions on risk appraisal and vaccination uptake using only experimental studies. Limitations of the interventions themselves, and those caused by study methods and reporting, mean that the potential value of this type of review is lost. Instead, its value is in shining a light on the paucity of experimental studies in this area, and the quality of methods and reporting used. Future experimental studies should examine interventions that focus exclusively on increasing risk and efficacy appraisal compared to controls, use conditional measures of risk, and improve reporting to enable both more accurate coding of intervention content and more accurate assessments of study bias.

Abstract
Objectives This study assessed influences on vaccination decisions among parents of young children and examined common vaccination information and advice sources. Methods Using panel samples of parents of children under 7 years, web-based surveys were conducted in 2012 (n = 2603) and 2014 (n = 2518). A vaccine decision-making typology (non-hesitant acceptors, hesitant acceptors, delayers, and refusers) was established and weighted population estimates of potential factors influencing parental vaccination decision (e.g., provider influence, source of information and advice) were computed by year and decision type. Results Delayers and refusers were more likely than acceptors to know someone whose child experienced a severe reaction to a vaccine or delayed/refused vaccine(s). High proportions of delayers (2012: 33.4%, 2014: 33.9%) and refusers (2012: 49.6%, 2014: 58.6%) reported selecting their healthcare provider based on whether the provider would allow them to delay/refuse vaccines. Providers were the most frequently reported trusted vaccine information source among all parents, though more often by acceptors than refusers (2012, 2014: p < 0.01). We found differing patterns of provider advice-seeking and internet as a reliable vaccine information source by group. Among those who had considered delay/refusal, trust in their healthcare provider's advice was the most common reason cited for their decision reversal. Conclusions for Practice Provider trust and communication along with varying degrees of personal-network influences likely contribute to immunization decisions of parents. Vaccine hesitant parents often seek providers amenable to accommodating their vaccine beliefs. Providers may benefit from vaccine communication training as their recommendations may influence hesitant parents to immunize their children.

Abstract
Suboptimal vaccination rates are a significant problem in many countries today, in spite of improved access to vaccine services. As a result, there has been a recent expansion of research on how best to communicate about vaccines. The purpose of the present article is to provide an updated review of published, peer-reviewed empirical studies that examined the effectiveness of gain versus loss framing (i.e., goal framing) in the context of vaccine communication. To locate studies, we examined the reference list from the previous meta-analytic review (O'Keefe & Nan, 2012), and we conducted systematic searches across multiple databases. We included 34 studies in the qualitative synthesis. The relative effectiveness of goal-framed vaccine messages was often shown to depend on characteristics of the message recipient, perceived risk, or situational factors, yet most effects were inconsistent across studies, or simply limited by an insufficient number of studies. Methodological characteristics and variations are noted and discussed. The review points to several directions concerning moderators and mediators of framing effects where additional rigorous studies would be needed.

Abstract
Pregnancy is an ideal time to communicate with women about vaccines for themselves and their infants, yet maternal immunization rates remain suboptimal. This study aimed to identify clinic, provider, and staff-related attributes and facilitators to be utilized for a comprehensive vaccine intervention in ob-gyn clinical settings. We conducted in-depth interviews with 24 providers, both healthcare providers (e.g., physicians, nurse practitioners, midwives) and practice managers, from urban and suburban ob-gyn practices in Georgia and Colorado about their immunization attitudes, practices, and patient experiences. Qualitative analyses included Pearson correlation tests to evaluate patterns and relationships within the data to determine themes. Six major themes emerged: 1) strong provider "buy in" for maternal immunization; 2) the supporting role of clinical/interpersonal cues for vaccine promotion; 3) varying provider-patient communication approaches and its influence on maternal and pediatric uptake; 4) an urgent need for a designated office immunization champion; 5) reimbursement and practice implementation challenges; and 6) region differences in attitudes and values toward maternal immunization. Although providers expressed strong support for maternal immunization practices and offered environmental cues for vaccine promotion, practices often lacked a designated, structured role for an immunization champion equipped to manage delicate conversations with patients. The findings reflect needs for immunization champion identification, training, and support, along with best practices guidelines to improve coordination of vaccine promotion and delivery efforts in ob-gyn provider offices. Additionally, provider training on communication approaches to enhance acceptance and uptake of maternal vaccines is warranted.

Abstract
Although much is known about factors contributing to variation in pediatric immunization uptake, there is a need for synthesis of effective vaccine promotion strategies. With growing public health concern on how to best sustain high pediatric immunization rates, and improve where the rates are suboptimal, this review offers evidence gathered from several studies on the achievement of these goals. We identified and analyzed reported findings on childhood (primarily ≤ 7 years) immunization outcomes from tested intervention strategies that focused on parents, guardians, and caregivers, as well as providers, clinics/practices, and communities. The findings suggest that targeted and tailored interventions offer substantial possibilities, especially in a combined manner. We describe promising intervention models that have been operationalized with success and provide evidence for scalability across contexts. Moreover, they are sensitive to parents' and providers' needs, are feasibly integrated in daily clinical practice, and account for broader community concerns and issues.

Abstract
Recognition of the acute and chronic burden of respiratory syncytial virus (RSV) lower respiratory tract infections (LRTI) sparked a wave of initiatives to develop preventive and therapeutic products against the pathogen in recent years. RSV is a leading cause of hospitalization in infants in industrialized and developing countries, has been causally linked to recurrent wheezing during childhood, associated with pediatric asthma, and is an important cause of mortality in the first months of life in the developing world. Significant changes in the epidemiology, clinical manifestations, and severe consequences of LRTI may emerge in the next decade with the advent of novel preventive strategies against RSV. This manuscript outlines some of these changes and discusses potential scenarios based on the current literature and experiences with other pathogens.

Abstract
Pregnant women are a vulnerable group who are needed in clinical research studies to advance prevention and treatment options for this population. Yet, pregnant women remain underrepresented in clinical research. Through the lens of the socioecological model, we highlight reported barriers and facilitators to recruitment and retention of pregnant women in studies that sought their participation. We trace historical, policy-based reasons for the exclusion of pregnant women in clinical studies to present-day rationale for inclusion of this group. The findings highlight why it has been difficult to recruit and retain this population over time. A body of literature suggests that integrative sampling and recruitment methods that leverage the influence and reach of prenatal providers will overcome recruitment challenges. We argue that these strategies, in combination with building strong engagement with existing community-based organizations, will enable teams to more effectively promote and retain pregnant women in future longitudinal cohort studies.

Abstract
The increasing numbers of vaccine-hesitant parents poses a threat to personal and public health through a resurgence of vaccine-preventable diseases. Understanding the factors underlying vaccine-hesitant parents' fears is a necessary step toward designing interventions to overcome them. Educational interventions appear more successful when combined with personal interactions. Providers are the most important influence on parental vaccine decisions. Research should focus on designing effective interventions that facilitate effective parent-provider communication around this issue.

Abstract
Parental refusal or delay of childhood vaccines is increasing. Barriers to vaccination among this population have been described, yet less is known regarding motivating factors. Researchers are beginning to evaluate various approaches to address the concerns of "vaccine-hesitant" parents, but few studies have evaluated the effect of interventions on timely vaccine uptake. Several models for communicating with vaccine-hesitant parents have been reported for healthcare providers; however, the effectiveness and utility of these strategies has not been quantified. This article reviews the known barriers to vaccination reported by vaccine-hesitant parents and the current evidence on strategies to address parental vaccine hesitancy.

Abstract
OBJECTIVE We examined pregnant women's intention to obtain the seasonal influenza vaccine via a randomized controlled study examining the effects of immunization history, message exposure, and sociodemographic correlates. METHODS Pregnant women ages 18-50 participated in a randomized message framing study from September 2011 through May 2012. Venue-based sampling was used to recruit racial and ethnic minority women throughout Atlanta, Georgia. Key outcomes were evaluated using bivariate and multivariate analyses. RESULTS History of influenza immunization was positively associated with intent to immunize during pregnancy [OR=2.31, 90%CI: (1.06, 5.00)]. Significant correlates of intention to immunize included perceived susceptibility to influenza during pregnancy [OR=3.8, 90% CI: (1.75, 8.36)] and vaccine efficacy [OR=10.53, 90% CI: (4.34, 25.50)]. Single message exposure did not influence a woman's intent to vaccinate. CONCLUSIONS Prior immunization, perceived flu susceptibility and perceived vaccine effectiveness promoted immunization intent among this population of pregnant minority women. Vaccine efficacy and disease susceptibility are critical to promoting immunization among women with no history of seasonal influenza immunization, while those who received the vaccine are likely to do so again. These findings provide evidence for the promotion of repeated exposure to vaccine messages emphasizing vaccine efficacy, normative support, and susceptibility to influenza.
