Addressing Parental Vaccine Hesitancy towards Childhood Vaccines in the United States: A Systematic Literature Review of Communication Interventions and Strategies

Does a correlation exist between delayed vaccination and a decreased vaccine confidence?

Delay in vaccination schedule may result in increased risk of vaccine-preventable outbreaks. Lack of parental confidence in vaccines and sociodemographic factors could be related to those delays. Vaccine Confidence Index (VCI) is an indicator to estimate confidence in vaccines, composed of simple dimensions about it and evaluated using a 5-point Likert scale. Objectives of this study, conducted in the Region of Murcia, Spain, were to determine which sociodemographic factors were associated with delayed administration in measles, mumps and rubella (MMR) vaccine, both first and second doses, and to evaluate if there were differences in parental vaccine confidence of children who were delayed on MMR vaccine schedule compare to vaccinated on time. The 2019-2020 (first dose) and 2016-2017 (second dose) cohorts were divided into four categories: vaccinated on time, slightly delayed, moderately delayed and highly delayed. Online questionnaire was sent to their parents, followed by a telephone questionnaire for non-responders. Regarding MMR first dose, a significant association was found between delay and birth order and intellectual/motor delay of children. Parental educational status, the main source of vaccine information and the social networks more frequently used by parents were also associated with delay. Suffering motor/intellectual delay and the obstacles to vaccination process derived from caring for other siblings were associated with delay in second MMR dose. The VCI decreased significantly in first dose group as delay increases but did not change in the second one. Confidence in vaccines and sociodemographic factors, respectively, were associated with delaying MMR first and second dose.

Use of narratives to enhance childhood vaccine acceptance: Results of an online experiment among Canadian parents

Identifying effective interventions to promote children's vaccination acceptance is crucial for the health and wellbeing of communities. Many interventions can be implemented to increase parental awareness of the benefits of vaccination and positively influence their confidence in vaccines and vaccination services. One potential approach is using narratives as an intervention. This study aims to evaluate the effects of a narrative-based intervention on parents' attitudes and vaccination intentions. In a pre-post experiment, 2,000 parents of young children recruited from an online pan-Canadian panel were randomly exposed to one of the three videos presenting narratives to promote childhood vaccination or a control condition video about the importance and benefits of physical activity in children. Pre-post measures reveal a relatively modest but positive impact of the narratives on parents' attitudes and intention to vaccinate their child(ren). The results also suggest that narratives with more emotional content may be more effective in positively influencing vaccine attitudes than the more factual narrative. Using narratives to promote vaccination can positively influence parents' views and intentions toward childhood vaccines, but research is still required to identify the best components of such interventions.

Factors Associated With Repeat Pediatric Influenza Vaccination Among Inconsistent Vaccinators

Promoting consistent vaccination practices may help improve suboptimal influenza vaccination rates. This study evaluated the prevalence and correlates of repeat influenza (flu) vaccination among children who had previously received the vaccine inconsistently. An online survey study was conducted in 2022 among parents of commercially insured children ages 3 to 19 years who were previously inconsistently vaccinated. Of 317 respondents, 85% reported that their child received a flu vaccine in the 2021 to 2022 flu season. Among these parents, 61% reported concern that their child would get sick from flu as the most important reason for vaccinating. Repeat vaccination was less likely among parents who reported that school/daycare requirements were a reason for vaccinating in the prior season (odd ratio [OR] = 0.17, 95% confidence interval [CI] = 0.05-0.55). Our findings suggest that school policies may improve vaccination rates among inconsistent vaccinators.

Bibliometrics analysis and knowledge mapping of pertussis vaccine research: trends from 1994 to 2023

PURPOSE

This study aims to use bibliometric methods to explore the evolving landscape, hotspots, and emerging frontiers of pertussis vaccine research, providing deeper insights into the current research landscape and guiding future vaccine development efforts.

METHODS

We conducted a comprehensive search of the Web of Science Core Collection database (WoSCC) from January 1, 1994, to December 31, 2023, employing search terms related to vaccination (vacc* or immun*) and pertussis (pertussis, Whooping Cough, Bordetella pertussis, B. pertussis, Bordetella pertussis infection, or B. pertussis infection) in the Title or Author keywords fields. Bibliometrics analysis of pertussis research was performed utilizing the bibliometrix-biblioshiny package in RStudio, alongside CiteSpace and VOSviewer software.

RESULTS

In total, 2,623 records were analyzed, comprising 89.63% (n = 2,351) original research articles and 10.37% (n = 272) review articles. The study revealed that academic research on the pertussis vaccine was growing at a rate of 4.64% per year. The United States and Canada lead in the number of publications. GlaxoSmithKline and the Centers for Disease Control & Prevention- United States emerged as leading institutions, with Halperin SA and Locht C as the most active authors. Vaccine was the most influential journal. Most studies focused on vaccine effectiveness duration, vaccination schedules for high-risk groups, and people's attitudes toward vaccination.

CONCLUSION

Our analysis showed increasing interest of researchers in pertussis literature, yet current research mainly emphasized expanding vaccine coverage and optimizing strategies, neglecting new vaccine development. This emphasized the need for prioritizing novel pertussis vaccines to tackle the resurgence challenge.

Parental knowledge and attitudes to infant immunization in the context of RSV: All about confidence?

BACKGROUND

Recently, the first RSV vaccines have been approved, but vaccine hesitancy still poses great challenges to immunization programs.

OBJECTIVE

To investigate this phenomenon in the context of the new RSV vaccines and an increased virus activity in 2022/23, we assessed parental knowledge and attitudes towards general childhood and RSV vaccines.

METHODS

Parents of infants from 0-36 months completed an online questionnaire on demographics, socio-economic status, mental well-being, knowledge on RSV and perceptions of disease, attitudes to general childhood and RSV vaccines. The survey was conducted from February-June 2023 in the region of Regensburg, Germany. We compared continuous or categorical data with two-sided t-tests or Chi-square tests, respectively. Linear and logistic regression models were used to adjust for confounders.

RESULTS

From 191 survey participants, 84 % had never refused any recommended vaccination and 91 % trusted their paediatrician's information. 11 % felt that children should have fewer vaccinations or rather get over the illness. Parents who were supportive or undecided about RSV vaccination were less likely to be vaccine hesitant in general (OR 0.03, p < 0.001; OR 0.13, p = 0.003). 58 % reported to have basic or good knowledge on RSV, correlating with a higher socioeconomic index (p = 0.049). 24 % were undecided about RSV immunization, while all parents rated its benefit high in the child's first year of life. Parents who refused RSV vaccination were less concerned about the infection compared to vaccine supporters (OR 0.44, p < 0.001). Parents with previously hospitalized (OR 3.88, p = 0.017) or preterm born children (OR 5.12, p = 0.026) were generally more concerned.

CONCLUSION

Many factors influence parental decision-making leading to three main groups of attitudes: vaccine acceptors, refusers and hesitant but accessible parents. They (24%) represent the "target group" to increase vaccine uptake. Information on the vaccine-preventable disease reduces vaccine hesitancy, underlining the importance of healthcare professionals who remain an important source of trust.

Empowering Unvaccinated Youth: Feasibility, Acceptability, and Efficacy of a COVID-19 Serious Game-Based Intervention

Objective: To evaluate a serious game-based intervention's feasibility, acceptability, and efficacy in encouraging coronavirus disease (COVID-19) vaccination among 11-14-year-olds in the United States and assess participant experiences. Materials and Methods: The study, grounded in social cognitive theory and health belief model, recruited and engaged 32 English-speaking parent-child dyads with unvaccinated youths via snowball sampling and social media outreach. These dyads were randomly assigned to either the COVID-19 serious game-based intervention group (n = 16) or a usual care group (n = 16). The study measured beliefs, self-efficacy, and intentions regarding vaccination using surveys before and after the intervention, with follow-up at 2 months to evaluate vaccine uptake. Semistructured interviews provided insights into the gaming experience and study process. Results: All 32 eligible parent-youth dyads (16 in each group) completed the study with full participation. Most participants were Black or African American fathers, making up 75% and 81.3% of the intervention and control groups, respectively. The intervention impacted vaccine uptake, with 75% of the intervention group vaccinating their children compared with 37.5% of the control group [χ2(1, n = 32) = 4.57, P = 0.033]. Key factors for vaccine uptake included parents' motivation and youths' perceived susceptibility, with correlations of r(30) = 0.66, P = 0.006, and r(30) = 0.55, P = 0.029, respectively. The intervention reshaped youth perceptions about self and community protection. Participants expressed overall satisfaction with both the intervention and the study process. Conclusions: The intervention was found to be feasible and acceptable, with potential for integration into youth vaccination strategies to support COVID-19 vaccine decision-making.

Level of hesitation of parents about childhood vaccines and affecting factors: a cross-sectional study in Turkey

BACKGROUND

Hesitancy rates for childhood vaccines are increasing on a global scale. It was reported in previous studies that many factors affect vaccine hesitancy. The present study was designed to determine the prevalence of childhood vaccination hesitancy in parents and to determine the factors affecting it.

METHODS

This descriptive, cross-sectional study was conducted with 350 parents who had at least one child aged two years and younger, who applied to Family Health Centers in the city of Mardin in the Southeastern Anatolia Region of Turkey, between January and March 2022. The "Parental Attitudes Towards Childhood Vaccines (PATCV) Questionnaire" was used to collect the data, which were analyzed by using the SPSS (Statistical Package for Social Sciences) for Windows 22.0 program. The Logistic Regression Analysis was used to determine the factors affecting parental attitudes toward childhood vaccines.

RESULTS

A total of 32.0% of the parents were found to be hesitant about vaccinations and 3.4% did not have at least one vaccination for their children. Significant relationships were detected between income status, education status, thoughts about vaccinations, parents having adult vaccinations, hesitant to have self-vaccination, considering vaccine necessary, and parental attitudes towards childhood vaccinations (p < 0.05). According to the Regression Analysis, parents who had adult vaccinations had reduced hesitation about childhood vaccines 0.506 times (p = 0.032; OR = 0.506; 95%CI = 0.271-0.943). Considering the vaccine necessary reduced the hesitation about childhood vaccines by 0.440 times (p = 0.011; OR = 0.440; 95%CI = 0.234-0.828).

CONCLUSIONS

The hesitations of parents about childhood vaccines were found to be high. The reasons for vaccine hesitancy must be examined in detail and strategies must be developed in this regard.

Barriers to Childhood Immunization in Rural and Remote Areas: A Qualitative Exploration From the Perspectives of Community Leaders in Sindh, Pakistan

Despite overall improvements observed at the national level, there is a significant disparity in childhood vaccination coverage rates between urban and rural regions, particularly within tribal and remote areas in Pakistan. Our study aimed to explore the views of community/tribal leaders concerning barriers and their local solutions for improving vaccine uptake, with a specific focus on remote settings. An exploratory qualitative research study was conducted from July to September 2019 in Shikarpur, Sindh, Pakistan. We interviewed 11 community leaders, after developing a semi-structured interview guide based on the health belief model. Following validation, the collected data was transcribed and subsequently translated into the English language. A stepwise process of manual familiarization, coding, theme generation, and theme review using an inductive approach was followed. While most of the rural community leaders expressed a willingness to support vaccinations, numerous unexplored barriers were identified. These barriers included an unsustainable communication system heavily dependent on polio mobile teams, discourteous behavior of healthcare personnel, cultural restrictions that limited women's involvement, economic hardships, limited transportation options, insufficient collaboration with the education sector, poor knowledge among community leaders, and security concerns. Additionally, they proposed some innovative solutions of information dissemination methods through the Ottaque system, ethics-based training, subsidized transportation services or voucher system, and addressing security concerns in collaboration with community leaders. Our findings suggest policymakers take both community leaders and members for an inclusive policy-making process to redraft the special policy for these remote and rural areas.

"I Don't Understand How These Two Things Go Together": Toward a Theory of Risk Ecologies

Rhetorical ecological approaches, which posit that messages exist not as isolated entities but instead in the relations of a dynamic network, offer a valuable lens for examining the discursive construction of health-related risk. Drawing from interview data (n = 50) exploring maternal vaccine refusal, this article expands upon these frameworks to trace how intertextual, synchronous messages - particularly those associated with prenatal and infant nutrition - influence mothers' understanding about early childhood vaccine-related risk. Ultimately, I propose the notion of a risk ecology - a network of intertextual messages which shape and constrain sense-making about risk as it emerges within a particular moment and biosocial community.

Key factors in complex public health interventions to address vaccine hesitancy using a multidisciplinary approach: the VAX-TRUST project

The VAX-TRUST project addresses vaccine hesitancy in seven European countries with a systematic and evidence-based approach. Interventions, targeting healthcare professionals, draw from behavioural and social theories. A checklist, inspired by the TIDieR (Template for Intervention Description and Replication), ensures a detailed description of actions, transparency and replicability. The intervention development process begins with collaborative meetings and systematic revisions, concluding with external evaluations for replicability in diverse public health contexts. This study aims to provide valuable insights for future complex interventions in public health, based on lessons learnt to reduce the risk of vaccine-preventable diseases. The analysis of educational interventions within the VAX-TRUST project has led to the definition of precise guidelines to ensure their replicability and adaptation to various contexts, attempting to establish a universally applicable approach. Active participant engagement and consideration of local social dynamics, beyond information transmission, have emerged as key factors to improve intervention effectiveness. Various educational tools and collaboration with academic institutions have contributed to strengthening credibility.

The Delicate Situation of Childhood Vaccination: On the Dispreferredness of Soliciting Parents' Intent to Vaccinate

In the Netherlands, parents of newborns typically participate in two-, four-, and eight-week medical consultations to monitor their children's development and discuss vaccinations, which will not be administered before eight weeks. During these visits, healthcare professionals routinely ask parents if they intend to vaccinate their children (i.e. to participate in the National Immunization Program). Using Conversation Analysis, we examine 62 videotaped consultations and present two lines of evidence to argue that the sequence initiated by professionals wherein they solicit parents' intent to vaccinate is dispreferred. First, this action is routinely deferred by preliminary sequences. Second, when professionals eventually initiate this action (i.e. if it is not preempted by parents during pre-sequences), they orient to its dispreferred status, for example by highlighting benefactive details of vaccination. We discuss the possible existence of asymmetrical (initiator-sided) pre-sequences, why soliciting parents' vaccination intent might be dispreferred, and implications for the design of communication interventions.

Impact of the COVID-19 pandemic on self-paid vaccination intentions for children: a cross-sectional study in China

OBJECTIVES

While it is widely accepted that COVID-19 has disrupted routine vaccination globally, the long-term impact of COVID-19 on parental vaccination intentions is uncertain. This study aims to estimate whether COVID-19 impacted parental intentions for self-paid vaccines, and provides suggestions for local vaccination policy and intervention strategies accordingly.

METHODS

A questionnaire-based cross-sectional survey was conducted among 2212 caregivers in Zhejiang province between 22 March and 30 June 2023. The following information was collected: sociodemographic characteristics, self-paid vaccination related intentions and behaviours, and vaccine hesitancy measured by the Vaccine Hesitancy Scale. Multiple multinomial logistic regression models were used to analyse the factors influencing the change in vaccination intentions.

RESULTS

In total, 19.32% (n=390) of respondents increased their intention to immunise their children with self-paid vaccines after the COVID-19 epidemic, 9.16% (n=185) decreased their intention, and 71.52% (n=1444) of respondents indicated that the COVID-19 epidemic did not affect their intention. The major reason for increased intentions was 'Vaccines are effective in preventing diseases' (83.89%) and for decreased intentions was 'Worried about the side effects of vaccines' (65.95%). A higher hesitancy degree (OR=2.208, p=0.0001), reduced trust in vaccines after COVID-19 (OR=16.650, p<0.0001), doctors' recommendation of Expanded Programme on Immunization vaccines (OR=2.180, p=0.0076), and non-perfect satisfaction with vaccine information (all OR>1, all p<0.05) were considered to be drivers of decreased intention.

CONCLUSION

Although the intentions of self-paid vaccinations were not largely influenced, nearly 30% of caregivers' vaccination intentions changed after the COVID-19 pandemic and most of them increased their intentions. In addition, vaccination history of self-paid vaccines, vaccine information, vaccine trust and doctors' recommendations were the active factors for self-paid vaccination. Therefore, education on the knowledge of self-paid vaccines for caregivers should be implemented to increase their vaccination intentions and decrease the threat of infectious diseases to children's health.

COVID-19 and influenza vaccine-hesitancy subgroups

Health communicators are faced with the challenge that people can hesitate vaccines for different reasons. Our aim was to identify and describe the qualities of distinct COVID-19 and influenza vaccine-hesitancy subgroups to facilitate the development of tailored vaccine-hesitancy communication. In two studies, we used agglomerative hierarchical cluster analysis to identify COVID-19 (N = 554) and influenza (N = 539) vaccine-hesitancy subgroups in the general population based on nine vaccine hesitancy-related variables (intent to get vaccinated, perceived vaccine safety, perceived vaccine efficacy, perceived disease threat, perceived vaccination responsibility, perceived vaccination convenience, distrust in authorities, conspiracy mentality, and reliance on anecdotal testimonies). We identified and described six distinct COVID-19 vaccine-hesitancy subgroups (the Vaccination Positive, the Ambivalent, the Fearing Skeptic, the Unconvinced, the Constrained Skeptic, and the Vaccination Opponent), and three influenza vaccine-hesitancy subgroups (the Vaccination Positive, the Complacent, and the Vaccination Opponent), with different levels of hesitancy. We discuss the implications of the results for health communicators. Our results shed light on the (dis)similarities between people who hesitate COVID-19 and influenza vaccines and suggest that there is greater variety in hesitancy concerning COVID-19 vaccinations than influenza vaccinations. These findings can be used to design and test tailored vaccination messages.

"Anees Has Measles": Storytelling and Singing to Enhance MMR Vaccination in Child Care Centers Amid Religious Hesitancy

This study explores the enhancement of MMR vaccination rates in the deep south of Thailand through a culturally tailored intervention that incorporates storytelling and singing, aligning with local cultural and religious values. The "Anees has Measles" intervention, developed with input from community stakeholders including health workers, religious leaders, and parents, featured traditional melodies in its singing activities. The intervention comprised two main components: storytelling sessions and singing activities, both utilizing culturally resonant content and formats to effectively engage the community. Conducted from December 2019 to March 2020 across eight districts in five provinces, the study targeted children aged 18 months to 5 years in government child care centers. Results indicated a substantial increase in MMR vaccination coverage from 44.3% to 72.0% twelve months post-intervention, and further to 77.0% at 48 months post-intervention, representing a significant and sustained improvement (p < 0.001). This marked and continuous increase demonstrates the effectiveness of culturally adapted health education in areas with significant vaccine hesitancy. The findings highlight the importance of integrating culturally and religiously sensitive methods into public health strategies, significantly enhancing vaccine acceptance and coverage in diverse and conservative settings. This approach suggests a broader applicability for similar interventions in comparable contexts globally.

Exploring the relationship between vaccine hesitancy and mothers' perspectives on COVID-19 vaccines for children ages 5-11 years during the omicron predominant period 2021-2022: a qualitative study

Background

The United States Food and Drug Administration authorized COVID-19 vaccines for children ages 5-11 years in October 2021 during the Omicron predominant period. Parental vaccine hesitancy was prevalent during this time, resulting in low childhood COVID-19 vaccine uptake. Most studies exploring factors influencing parental vaccine hesitancy have focused on racial and ethnic minorities and lower socioeconomic populations; however, there is little knowledge of the drive drivers of vaccine hesitancy among White parents with higher education and socioeconomic statuses.

Methods

We conducted semi-structured interviews with a sample of 15 White mothers of children ages 5-11 years in Atlanta, GA, between October-December 2021. Thematic analysis was performed using NVivo 12.

Results

Mothers were college-educated, homeowners, and fully vaccinated against COVID-19. Key findings included decreased pediatrician's recommendations for COVID-19 vaccines, reliance on information from specialized doctors and scientists, distrust in public health authorities, high risk-perception of COVID-19 vaccines, and low risk-perception of COVID-19 disease. Factors related to vaccine acceptance were altruism and practicality.

Conclusion

This study adds to the sparse literature on reasons for vaccine hesitancy among White mothers of children ages 5-11 years with higher educational and socioeconomic status. Improving vaccine uptake among this group is critical for protecting the health of their children and other vulnerable populations. Tailored vaccine messaging and intervention are warranted to address their unique attitudes, beliefs, and behaviors. An enhanced understanding of the factors influencing subpopulations of parents can help vaccine policymakers and healthcare providers improve efforts to reduce vaccine hesitancy, particularly for new vaccines.

The Impact of COVID-19 Vaccine Controversy on Parents' Perceptions of Routine Vaccinations

Background The COVID-19 pandemic has significantly influenced public perceptions and behaviors related to vaccination. Understanding parental attitudes, knowledge gaps, and vaccination practices post-pandemic is crucial for informing effective public health strategies. This study aimed to investigate parental attitudes, knowledge, and practices toward routine childhood vaccination in the post-COVID-19 era, emphasizing shifts in perspectives and implications for vaccination strategies. Methodology A cross-sectional survey was conducted among 498 parents to assess their attitudes, knowledge, and practices regarding vaccination. Data were analyzed using descriptive statistics, chi-square tests, and t-tests where applicable, with p-values <0.05 considered statistically significant. Results The study revealed diverse parental attitudes toward vaccination post-COVID-19. While a majority (72.9%) maintained positive attitudes toward vaccination schedules and benefits, concerns regarding vaccine safety and efficacy were noted. Knowledge gaps persisted, with 16.5% strongly agreeing that children's vaccinations are weak and have no impact on disease prevention. Despite high adherence to vaccination schedules (68.9%), motivations behind vaccine administration were questioned, as 48.2% strongly disagreed that vaccination was solely for regulatory purposes. Conclusions Post-COVID-19, parental attitudes toward vaccination have evolved, reflecting increased concerns about safety and efficacy. Addressing knowledge gaps, combating misinformation, and enhancing trust in vaccination programs are imperative. Tailored communication strategies, education campaigns, and policy interventions are essential to promote vaccination acceptance and safeguard public health resilience in the post-pandemic era.

Contributions and Impact of Health Communication Research to Vaccination Efforts and Acceptance

Vaccines (a medical product) and vaccination recommendations (expert advice on who should receive, when, and how often) have grown in importance and prominence in the past 15 years, including because of a recent COVID-19 pandemic. This essay highlights contributions from vaccine and vaccination-related health communication research since 2010. This research has had significant impacts - that is, visible and discernible positive effects - on the ways health communication is undertaken broadly (e.g. at the campaign level) and at the health care provider-patient level (e.g. conversations with parents and patients regarding vaccine benefits, risks, and safety). As this essay illustrates, health communication research has resulted in greater use of formative research to guide vaccination campaign and education efforts, better identification and understanding of the factors behind vaccination delay and declination, and greater recognition that communication efforts can fail to achieve desired outcomes or generate unintended consequences. Health communication research has also documented the powerful influence of healthcare provider communication on parent and patient understanding and compliance with immunization recommendations. Importantly, this research has also shown the characteristics of provider-patient communication matter much. Healthcare providers must have or establish a high degree of trust, be well-versed in vaccine efficacy and safety, and be adept at using their personal experiences, information tailoring/personalization, and evidence-based communication strategies to increase the likelihood of success.

Sociodemographic Trends and Correlation between Parental Hesitancy towards Pediatric COVID-19 Vaccines and Routine Childhood Immunizations in the United States: 2021-2022 National Immunization Survey-Child COVID Module

Multiple factors may influence parental vaccine hesitancy towards pediatric COVID-19 vaccines and routine childhood immunizations (RCIs). Using the United States National Immunization Survey-Child COVID Module data collected from parents/guardians of children aged 5-11 years, this cross-sectional study (1) identified the trends and prevalence estimates of parental hesitancy towards pediatric COVID-19 vaccines and RCIs, (2) examined the relationship between hesitancy towards pediatric COVID-19 vaccines and RCIs, and (3) assessed trends in parental hesitancy towards RCIs by sociodemographic characteristics and behavioral and social drivers of COVID-19 vaccination. From November 2021 to July 2022, 54,329 parents or guardians were interviewed. During this 9-month period, the proportion of parents hesitant about pediatric COVID-19 vaccines increased by 15.8 percentage points (24.8% to 40.6%). Additionally, the proportion of parents who reported RCIs hesitancy increased by 4.7 percentage points from November 2021 to May 2022 but returned to baseline by July 2022. Over nine months, parents' concerns about pediatric COVID-19 infections declined; however, parents were increasingly worried about pediatric COVID-19 vaccine safety and overall importance. Furthermore, pediatric COVID-19 vaccine hesitancy was more prevalent among parents of children who were White (43.2%) versus Black (29.3%) or Hispanic (26.9%) and those residing in rural (51.3%) compared to urban (28.9%) areas. In contrast, RCIs hesitancy was higher among parents of children who were Black (32.0%) versus Hispanic (24.5%) or White (23.6%). Pediatric COVID-19 vaccine hesitancy was 2-6 times as prevalent among parents who were RCIs hesitant compared to those who were RCIs non-hesitant. This positive correlation between parental hesitancy towards pediatric COVID-19 vaccines and RCIs was observed for all demographic and psychosocial factors for unadjusted and adjusted prevalence ratios. Parent-provider interactions should increase vaccine confidence, shape social norms, and facilitate behavior change to promote pediatric vaccination rates.

How a 'good parent' decides on childhood vaccination. Demonstrating independence and deliberation during Dutch healthcare visits

Childhood vaccination consultations are considered an important phase in parents' decision-making process. To date, only a few empirical studies conducted in the United States have investigated real-life consultations. To address this gap, we recorded Dutch vaccination conversations between healthcare providers and parents during routine health consultations for their newborns. The data were analysed using Conversation Analysis and Discursive Psychology. We found that the topic of vaccination was often initiated with 'Have you already thought about vaccination?' (HYATAV), and that this formulation was consequential for parental identity work. Exploring the interactional trajectories engendered by this initiation format we show that: (1) interlocutors treat the question as consisting of two types of queries, (2) conversational trajectories differ according to which of the queries is attended to and that (3) parents work up a 'good parent' identity in response to HYATAV, by demonstrating that they think about their child's vaccination beforehand and make their decisions independently. Our findings shed new light on the interactional unfolding of parental vaccination decisions.

The Vaccine Training Barometer: Assessing healthcare providers' confidence to answer vaccine-related questions and their training needs

Healthcare providers (HCP) are seen by the public as the most trustworthy source of information about vaccination. While HCPs could be a valuable partner to increase vaccine confidence in general, it is not clear whether they feel confident themselves to address questions concerning vaccination. In the context of the EU Joint Action on Vaccination (EU-JAV), the Vaccine Training Barometer, an online survey tool, was developed to assess how frequently HCPs receive questions about vaccination, how confident they feel to answer these questions, and to what extent they are willing to follow extra training. After a pilot test in Flanders, Belgium, the Barometer was launched and completed by 833 HCPs in Flanders and 291 HCPs in the Spanish regions of Catalonia, Navarre and Valencian Community from November 2020 until January 2021, during the COVID-19 pandemic, just before and during the start of the first COVID-19 vaccination campaigns. In both countries, HCPs frequently received questions about vaccination (mostly on a daily or weekly basis), and about two thirds of them indicated that the frequency of questions had increased during the three months prior to completing the survey. Most questions were about the side effects and safety of vaccines. In both countries, a considerable proportion of HCPs did not feel confident to answer vaccine-related questions (31.5% felt confident in Flanders, 21.6% in Spain). A large proportion of HCPs received questions in the last three months before the survey that they could not answer (52.4% of respondents in Flemish sample, 41.5% in Spanish sample). Only 11.4% (Flanders) and 11.3% (Spain) of the respondents felt they gained sufficient knowledge through their standard education to be able to answer questions about vaccination. Almost all respondents were willing to follow extra training on vaccination (Flanders: 95.4%, Spain: 96.6%). The Vaccine Training Barometer is thus a useful tool to monitor HCPs' confidence to answer questions about vaccination and to capture their training needs.

The COVID-19 pandemic and children with PANS/PANDAS: an evaluation of symptom severity, telehealth, and vaccination hesitancy

The current study assessed the impact of the COVID-19 pandemic on children with PANS/PANDAS, a condition characterized by sudden-onset obsessive-compulsive, tic, or restrictive eating symptoms following infection. We conducted an anonymous survey between February and June 2021 of 254 self-reported caregivers of minors with PANS/PANDAS. Caregivers answered questions regarding PANS/PANDAS symptoms, telehealth care, and intention to vaccinate their child against COVID-19. PANS/PANDAS symptoms during COVID-19 infections were assessed when applicable. Children's OCD symptoms and coercive behaviors towards caregivers, along with the caregivers' mental health, relationship satisfaction, and burden, were assessed using standardized questionnaires. A majority of respondents endorsed a negative impact on their child's friendships, relationships with extended family, hobbies, and academic skills due to the pandemic. Children with suspected or diagnosed COVID-19 experienced new or worsened psychiatric symptoms, particularly mood lability, OCD, and anxiety. Telehealth care was the preferred treatment modality if the child had mild symptoms of PANS/PANDAS. A majority of caregivers reported high levels of relationship dissatisfaction and caregiver burden. As expected, these data suggest an overall negative impact of the COVID-19 pandemic on children with PANS/PANDAS and their caregivers.

Individual and social determinants of COVID-19 vaccine hesitancy and uptake in Northwest Syria

INTRODUCTION

The COVID-19 outbreak devastated the fragmented health system in Syria, a war-torn country, and exaggerated the demands for humanitarian assistance. COVID-19 vaccination was rolled out in Northwest Syria, an area out of government control, in May 2021. However, vaccine acceptance rates are still minimal, which is reflected in the meager percentage of vaccinated people. The study aims to investigate the effectiveness of the humanitarian actors' plans to address the COVID-19 vaccine hesitancy and conclude practical strategies for boosting vaccine uptake in Northwest Syria.

METHODS AND MATERIALS

Two questionnaires were developed to collect data from humanitarian organizations involved in the COVID-19 vaccination campaign and people from northwest Syria. Data analysis was performed using SPSS 22 data analysis program.

RESULTS

According to the findings, 55.5% of people refused the COVID-19 vaccine. The results showed a knowledge gap and lack of evidence regarding humanitarian actors' strategies to address the vaccine's low uptake. Besides, it was found that doctors and medical workers were reliable sources of information about the vaccine. However, they were not systematically engaged in community mobilization and risk communication to promote people's perspectives on the vaccine.

CONCLUSION

Risk communication and community engagement programs were not significantly associated with increasing the COVID-19 acceptance rate. Humanitarian actors must reconsider their strategies to address vaccine hesitancy in Northwest Syria. These strategies should engage medical professionals through dialogue sessions on the realities of the pandemic and vaccine development mechanism based on a compelling and evidence-based approach.

An Evaluation of Messages to Promote Parental Intent to Vaccinate Children Aged <12 Years Against COVID-19

OBJECTIVES

Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19.

METHODS

In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations.

RESULTS

The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages.

CONCLUSIONS

Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

Strategies for Improving Vaccine Communication and Uptake

Vaccines have led to a significant decrease in rates of vaccine-preventable diseases and have made a significant impact on the health of children. However, some parents express concerns about vaccine safety and the necessity of vaccines. The concerns of parents range from hesitancy about some immunizations to refusal of all vaccines. This clinical report provides information about the scope and impact of the problem, the facts surrounding common vaccination concerns, and the latest evidence regarding effective communication techniques for the vaccine conversation. After reading this clinical report, readers can expect to: Understand concepts and underlying determinants of vaccine uptake and vaccine hesitancy.Understand the relationship between vaccine hesitancy and costs of preventable medical care.Recognize and address specific concerns (eg, vaccine safety) with caregivers when hesitancy is present.

Everyday Ethics in Ambulatory Pediatrics: Cases and Applications

This article presents three clinical scenarios that might be encountered in ambulatory pediatrics. The framework for ethical analysis presented by Dr Hughes in a separate article in this issue of the Journal is used to examine these clinical scenarios and demonstrate application of the framework. The three cases involve a physician being asked by parents to write a letter for better housing that would require the doctor to be dishonest; parents who decline to have their 8-month-old daughter vaccinated; and a physician who believes contraception is a sin and therefore would not prescribe it to a sexually active 17-year-old girl.

Evidence-Based Storytelling for a Strategic Roadmap to Promote Cancer Prevention via Adolescent HPV Vaccination in Northern New England

Vaccination rates for the human papillomavirus (HPV) among rural youth in northern New England lag those of more urbanized areas. Reasons include a lack of available medical offices, time constraints, perceptions of vaccines and HPV, and, to a smaller degree, delays caused by the COVID-19 pandemic. We have a responsibility to increase vaccinations in these communities. To do so, vaccination experts recommend addressing the three C's of vaccination hesitation: confidence, complacency, and convenience. With this framework as our foundation, in this article we detail a plan to address these important elements, and we add several more C's: clinics, communication, collaboration, community, capacity, and commitment to the list as we discuss the essential pieces-human, infrastructural, and perceptual-needed to create and promote successful, community-supported, school-based HPV vaccination clinics to serve youths aged nine to 18. We then integrate research and storytelling science into an innovative Persuasion Playbook, a guide for local opinion leaders to use in creating evidence-based, pro-vaccine messages on the community level to promote the clinics via evidence-based, pro-vaccination messages.

Gap between cognitions and behaviors among children's guardians of influenza vaccination: The role of social influence and vaccine-related knowledge

The seasonal influenza vaccine coverage remains suboptimal among children even though guardians expressed high willingness to vaccinate their children. This study aimed to determine the association between vaccine hesitancy and uptake to facilitate vaccination; thus, bridging the gap. A cross-sectional design, using stratified cluster random sampling, was conducted among guardians of 0-59-month-old Chinese children from July to October in 2019. A structural equation model was applied to explore the interrelationships between factors including vaccine hesitancy, vaccination, social influence, and relative knowledge among guardians. Of the 1,404 guardians, 326 were highly hesitant to vaccinate their children, 33.13% (108/326) of whom had vaccinated their children. Moreover, 517 and 561 guardians had moderate and low vaccine hesitancy, with corresponding vaccine coverage of 42.75% (221/517) and 47.95% (269/516). Guardians' gender, age, and education level were demographic variables with significant moderating effects. Social influence considered impact of communities, family members, friends, neighbors, healthcare workers, bad vaccination experience and sense on price. Actual vaccine uptake was negatively significantly associated with hesitancy (β = -0.11, p < .001) with positive association with social influence (β = 0.61, p < .001). Vaccine hesitancy was negatively significantly associated with relative knowledge (β = -2.14, p < .001) and social influence (β = -1.09, p < .001). A gap is noted between cognitions and behaviors among children's guardians regarding influenza vaccination. A comprehensive strategy including emphasizing benefits of the influenza vaccination, risk of infection, and ensuring high vaccine confidence among healthcare workers can help transform the willingness to engage in the behavior of vaccination.

Family Communication Patterns and Parents' Intentions to Vaccinate Their Child Against COVID-19

This study explored how family communication patterns relate to parental knowledge about COVID-19, vaccine confidence, and intentions to vaccinate their children. Parents from 4 states (Ohio, New York, Georgia, and Texas; n = 702) completed an online survey in March 2021. Results revealed that conversation orientation was positively associated with both COVID-19 knowledge and overall vaccine confidence, which were both positively associated with intentions to vaccinate one's child. The relationships between the 4 subscales of conformity and the outcome variables were mixed. We discuss the potential benefits of applying family communication patterns theory to complicated situations where parents are making health decisions for both themselves and their children.

Vaccination hesitation in children under five years of age: a scoping review

OBJECTIVES

to synthesize scientific evidence on vaccine hesitancy in children under five years of age and its associated factors.

METHODS

a scoping review, conducted according to the methodological structure proposed by the JBI. Searches were carried out in the Latin American and Caribbean Center on Health Sciences Information, Scientific Electronic Library Online and PubMed databases, including gray literature. Studies in English, Spanish and Portuguese were included, without temporal delimitation. Editorials, studies that did not address vaccine hesitancy in children under five years of age and were not aligned with the objective and research question were excluded. The sample consisted of 18 articles.

RESULTS

misinformation, concern about adverse effects, distrust about efficacy, affliction regarding administration simultaneously, and insecurity in relation to the laboratories were the reported reasons.

CONCLUSIONS

strategies are needed to combat the lack of information about immunobiological agents, as misinformation was the main factor in parents' vaccine hesitation.

Leveraging a Peer-to-Peer Approach to Mitigate Vaccine Misinformation and Improve Vaccine Communication During a Pandemic: Experiences From the Development of a Massive Open Online Course

The COVID-19 pandemic has not only led to massive global mortality and morbidity, but it has also fueled an infodemic of false and misleading information about COVID-19 and vaccines. The spread of misinformation and disinformation on vaccine safety and efficacy has contributed to vaccine hesitancy and distrust of public health institutions and has undermined the public health response to the COVID-19 pandemic. Because communication plays a monumental role in pandemic preparedness, a promising approach to countering the COVID-19 infodemic is empowering peers to serve as trusted messengers to provide accurate information using evidence-based communication approaches. With this in mind, we developed a massive open online course (MOOC) to provide the general public with the knowledge, skills, and resources to effectively navigate potentially contentious vaccine conversations with their peers, with a specific focus on parents. Within the first year of the course launch, 29,000 people had enrolled. Learners appreciated the information related to vaccine development, communication tips and techniques, and identifying and responding to vaccine misinformation. Over 1,000 learners who completed the course participated in an online evaluation survey. To address public distrust in healthcare providers, government, and science, our survey results indicate that peer-to-peer approaches to addressing vaccine hesitancy can empower community members to educate others and promote vaccine acceptance at scale.

Countering vaccine hesitancy: a systematic review of interventions to strengthen healthcare professionals' action

BACKGROUND

Vaccine hesitancy is relevant for healthcare professionals (HCPs) who face challenges in building trusting relationships with patients. Accordingly, the VAX-TRUST project has been developed to improve experiences of HCPs and patients dealing with vaccinations. To support VAX-TRUST, this work aimed to identify latest interventions targeted at HCPs to address hesitancy and increase vaccine uptake.

METHODS

A systematic review was conducted according to PRISMA by searching PubMed, Scopus and Embase. The protocol was registered on PROSPERO. Articles were eligible if evaluated interventions directly targeted at HCPs/healthcare students. The search was run on 26 January 2022. Articles published in 2016 or after were included.

RESULTS

A total of 17 492 records were identified; 139 articles were selected. Most articles were set in USA (n = 110). Over half had a pre-post design without a control group (n = 78). A total of 41 articles focused on single-component interventions, 60 on multi-component interventions involving only HCPs and/or students and 38 on multi-component interventions involving also other professionals. Main components were in-person education (n = 76), synchronous (n = 10) and asynchronous (n = 23) online learning, educational materials (n = 26), performance assessment and feedback (n = 33), electronic record changes (n = 30), role play/simulation (n = 21) and online games/apps (n = 5). Educational sessions were mainly about scientific update or communication. Outcomes of interventions were grouped in: vaccination rates (n = 69), knowledge (n = 32), attitudes (n = 26), confidence in counselling (n = 30) and acceptability (n = 16).

CONCLUSIONS

Apps, gaming, role play/simulations could represent innovative interventions. This review highlighted the need of delving into communication strategies and using more robust evaluations, longer follow-up and standardized measurements.

Bulgarian General Practitioners' Communication Styles about Child Vaccinations, Mainly Focused on Parental Decision Making in the Context of a Mandatory Immunization Schedule

The communication practices of general practitioners in relation with vaccines have not been a topic of wide scientific interest. In this article, we outline them in the context of Bulgaria. A representative, cross-sectional, quantitative, face-to-face survey was conducted among 358 Bulgarian general practitioners in 2022 using simple random sampling. We conducted an exploratory factor analysis using questions about the role of the GPs, which measure models of communication. Based on the factor analysis, we distinguished four communication styles. They were called: active communicator, restrictive communicator, informing communicator, and strained communicator. One-way ANOVA and the T-test were carried out to explore the connections between factor scores (communication styles) and other variables. One of the most important results in the study was that the informing physician (emphasizing the choice of the parents) was the most common model in Bulgaria. This is somewhat contradictory, because of the mandatory status of most vaccines. We found connections between the communication styles and other variables-such as the type of settlement, having a hesitant parent in the practice, recommendations of non-mandatory vaccines, and experience with vaccine-preventable diseases. On the basis of the factor analysis and analysis of relationships with other variables, we reached the conclusion that in Bulgaria, hesitant parents are not sufficiently involved in active, effective communication about vaccines by GPs.

Vaccination as a social practice: towards a definition of personal, community, population, and organizational vaccine literacy

BACKGROUND

A comprehensive and agreed-upon definition of vaccine literacy (VL) could support the understanding of vaccination and help policy-makers and individuals make informed decisions about vaccines.

METHODS

To shed some light on this debate and provide clarity, a scoping review was conducted to collect, summarize, and analyse available definitions of VL. Based on the findings of the scoping review, a new and comprehensive definition was proposed by a panel of experts.

RESULTS

Fifty-three articles were included, and two of them appeared to be the milestones around which the other definitions were grouped. The new definition proposed by the panel of experts included not only the personal perspective, but also the community, population, and organizational perspectives. Moreover, due to the increasing complexity of the social context with respect to the ability to navigate, understand, and use information and services, the definition of organizational vaccine literacy and the attributes of a vaccine literate healthcare organization have been proposed.

CONCLUSION

The new definition can contribute to the overall paradigm of health literacy and its distinct component of vaccine literacy, possibly improving the implementation of public health strategies to allow vaccination to be understood as a social practice by the entire community. This study describes the conceptual foundations, the competencies, and the civic orientation to be considered when developing measurement tools devoted to assessing VL at the different levels and in different contexts.

"I See a lot of Crazy Things and I Don't Know What to Believe": Lessons Learned about Health Literacy and Strategies for Communicating with Vaccine-Hesitant College Students

Throughout the COVID-19 pandemic, the American College Health Association (ACHA) has partnered with CommunicateHealth (CH) to develop COVID-19 mitigation resources for colleges and universities. In 2021, the CH team conducted a series of applied research activities to gain a nuanced understanding of factors that shape perceptions of risk and drive vaccine hesitancy among campus audiences-especially college students who are emerging adults (approximately ages 18 to 22). Based on our findings, CH and ACHA identified key traits of vaccine-hesitant college students and implications for future vaccine communication campaigns. First, vaccine-hesitant students are more likely to ask "why" and "how" questions such as "Why do I need to get vaccinated?" and "How was the vaccine developed and tested?". Secondly, these students want to have open, authentic dialogue rather than simply accepting health recommendations from a trusted source. Finally, the CH team noted that vaccine-hesitant students were not highly motivated by their own personal risk of getting sick from COVID-19; concern about spreading COVID-19 to others was a much stronger motivating factor. Leveraging these insights, CH and ACHA developed strategies to apply health literacy principles to reach vaccine-hesitant college students with the right information at the right time-and to leverage relevant motivators and overcome barriers to vaccination. By implementing these strategies, CH and ACHA developed clear and empowering educational materials about COVID-19 vaccination tailored to the unique information needs of vaccine-hesitant students.

Strategies for Working With Parents With Vaccination Hesitancy

The purpose of this article is to provide an overview of effective strategies for working with parents' vaccination hesitancy or refusal. An overview of historical and current trends in vaccination hesitancy and factors that contribute to and strategies for addressing vaccine hesitancy are discussed. This includes an emphasis on the critical role played by health care providers, as trusted advisors and a primary source of health care information, in encouraging vaccine acceptance. Legal and ethical implications are also considered. Vaccination hesitancy strategies are most effective if they are timely, multifaceted, and collaborative.

Exploring parents' views of the use of narratives to promote childhood vaccination online

BACKGROUND

Negative information about vaccines that spreads online may contribute to parents' vaccine hesitancy or refusal. Studies have shown that false claims about vaccines that use emotive personal narratives are more likely to be shared and engaged with on social media than factual evidence-based public health messages. The aim of this study was to explore parents' views regarding the use of positive narratives to promote childhood vaccination.

METHODS

We identified three ∼4-minute video narratives from social media that counter frequent parental concerns about childhood vaccination: parents and informed decision-making (online misinformation about vaccines); a paediatrician's clinical experience with vaccine-preventable diseases (prevention of still existing diseases); and a mother's experience with vaccine-preventable disease (risks of the disease). Focus group discussions were held with parents of children aged 0 to 5 years to assess their views on these three narratives and their general opinion on the use of narratives as a vaccine promotion intervention.

RESULTS

Four focus groups discussions were virtually held with 15 parents in December 2021. In general, parents trusted both health care provider's and parent's narratives, but participants identified more with stories having a parent as the main character. Both narratives featuring personal stories with vaccine-preventable diseases were preferred by parents, while the story about informed decision-making was perceived as less influential. Parents expressed the need for reliable and nuanced information about vaccines and diseases and felt that a short video format featuring a story was an efficient vaccine promotion intervention. However, many mentioned that they generally are not watching such videos while navigating the Web.

CONCLUSION

While vaccine-critical stories are widely shared online, evidence on how best public health could counter these messages remains scarce. The use of narratives to promote vaccination was well-perceived by parents. Future studies are needed to assess reach and impact of such an intervention.

Reliability but not bias: Developing a scale to measure preferred channels for risk information during the COVID pandemic

To develop a new measure of preferred sources for risk information, two studies asked respondents to indicate what channels they were reliant on for information about COVID-19, from 25 news channels ranging across the political spectrum. Unexpectedly, dependencies clustered around level of reliability rather than the political orientation of the news channel. In other words, each cluster included media channels from both the left and right side of the political spectrum, while dependencies clustered into sources that varied by the degree to which their content is reliable. Participants who turned to lower reliability channels indicated lower risk perceptions, less accurate probability estimations, reduced vaccination intentions, and lower protective behavioral intentions. Those inclined to use higher reliability channels indicated higher risk perceptions, more accurate probability estimations, increased vaccination intentions, and higher protective behavioral intentions. These relationships are discussed in terms of implications for our understanding of source reliance and risk perception, information sufficiency, and implications for both future research and public health interventions.

Say it right: measuring the impact of different communication strategies on the decision to get vaccinated

BACKGROUND

Vaccine hesitancy is a concerning menace to the control of vaccine-preventable diseases. Effective health communication could promote an overall understanding of the importance, risks, and benefits of vaccination and reduce vaccine hesitancy.

METHODS

In this survey, four fictitious newspaper articles addressing an emerging bogus disease and its vaccine were randomly assigned to participants. The first version focused on information about the disease; the second was akin to the first, including a case description and image. The third version focused on vaccine safety/efficacy; the fourth version was like the third, including a case description and image. After reading a single version of the article, participants responded if they would take the vaccine and if they would vaccinate their children. We used chi-squared tests for comparisons and investigated interactions with vaccine-hesitant attitudes.

RESULTS

We included 5233 participants between August/2021 and January/2022; 790 were caregivers of a child ≤ 5 years old, and 15% had prior vaccine hesitancy. Although most declared intention to take the vaccine, the percentage was highest among those exposed to the newspaper article focusing on the vaccine safety/efficacy with the case description and picture (91%; 95% confidence interval 89-92%), and lowest among participants exposed to the article focusing on the disease with no case description (84%; 95% confidence interval 82-86%). Similar trends were observed in the intention of offspring vaccination. We found evidence of effect modification by vaccine-hesitant attitudes, with a higher impact of communication focusing on vaccine safety/efficacy compared to that focusing on disease characteristics among hesitant participants.

CONCLUSION

Communication strategies focusing on different aspects of the disease-vaccine duet may impact vaccine hesitancy, and storytelling/emotive imagery descriptions may improve risk perception and vaccine uptake. Moreover, the effect of message framing strategies may differ according to previous vaccine hesitant attitudes.

Interventions for COVID-19 Vaccine Hesitancy: A Systematic Review and Narrative Synthesis

Vaccines effectively protect against COVID-19, but vaccine hesitancy and refusal hinder vaccination rates. This systematic review aimed to (1) review and describe current interventions for addressing COVID-19 vaccine hesitancy/refusal and (2) assess whether these interventions are effective for increasing vaccine uptake. The protocol was registered prospectively on PROSPERO and comprehensive search included Medline, Embase, CINAHL, PsycInfo, and Web of Science databases. Only studies that evaluated the effectiveness of non-financial interventions to address COVID-19 vaccine hesitancy were included, while those focusing intentions or financial incentive were excluded. Risk of bias for all included studies was evaluated using Cochrane risk of bias tools. In total, six articles were included in the review (total participants n = 200,720). A narrative synthesis was performed due to the absence of common quantitative metrics. Except for one randomized controlled trial, all studies reported that interventions were effective, increasing COVID-19 vaccination rates. However, non-randomized studies were subject to confounding biases. Evidence on the effectiveness of COVID-19 vaccine hesitancy interventions remains limited and further evidence is needed for the development of clear guidance on effective interventions to increase vaccine uptake.

Scale Development for COVID-19 Vaccine Hesitancy by Integration of Socio-Demographic and Psychological Factors

Vaccination is the most cost-effective way to maintain population health. However, it can only be effective if widespread acceptance is held. The efficacy of COVID-19 vaccines depends on their favor. When countries start to vaccinate their citizens, there is a certain level of skepticism about the effectiveness of the vaccines. The hesitancy study on vaccines has gained momentum following the pandemic. However, few studies have examined the link between the psychological and sociodemographic factors influencing the fit. This paper proposes integrating the concepts of the information systems success and stimulus-organism-response into a cognitive fit theory framework to explore the integration of psychological and sociodemographic factors in the receivers' reactions (n = 1510). This study analyses the factors that influence the hesitancy of vaccines and the public's refusal in Asia and Europe. Receivers' reactions were assessed to various stimuli and we explored the link between psychological and sociodemographic elements and the concept of fit. Two surveys were conducted following the scale development of Mackenzie. The first was to develop the fit scale, while the second was to validate the fit scale. The results of the second survey were analyzed using structural equation modelling. The results indicate that the scale's fit development is valid and reliable. The quality of the vaccine information, the psychological characteristics of the vaccine system, and vaccine receivers' satisfaction are also beneficial factors for emotional and cognitive fit. Maintaining the vaccines' quality and efficiency can help improve the fit between sociodemographic and psychological characteristics. It can also enhance receivers' satisfaction and encourage continued vaccine administration. This study is regarded as one of the first to examine and develop an emotional and cognitive fit scale for practitioners and researchers.

Vaccine Hesitancy Among Parents and Its Determinants During the Era of COVID-19 in Taif City, Saudi Arabia

Background Vaccine hesitancy is a growing concern worldwide, particularly during the COVID-19 pandemic. The aim was to investigate vaccine hesitancy and its determinants among parents in Taif, Saudi Arabia. Methods A cross-sectional study was conducted among parents using a validated and reliable questionnaire, the parent attitudes about childhood vaccines (PACV). Parents of children aged (two months to seven years) attending primary health care centers (PHCC) outpatient clinics were selected using a stratified sampling technique and interviewed to fill out the pre-structured questionnaire. Result The study included 301 parents, with 41.2% between the ages of 30-39 years and 25.2%% between 40-49 years. Mothers constituted 69.1% of the respondents. The most common sources of information regarding vaccinations were the doctor (34.9%), the internet (27.9%), and social media (16.6%). COVID-19 influenced the beliefs of more than half (52.5%) of parents regarding the importance of vaccinations. The median PACV score for vaccination hesitancy was 23.3/100, interquartile range (IQR) (13.3-33.3). The highest hesitation was among the age group of 30-39 years old (21.6%) and those whose beliefs were not influenced by the COVID-19 pandemic (16.1% vs. 5.7%) (p-value=0.003). The study found a significant difference in vaccine hesitancy rates between the different sources of information (p-value <0.001); parents who got their information about vaccinations from social media were more likely to be hesitant about vaccinations (40%). Concerns about side effects (93.8%), thinking that vaccines are not safe (84.4%), and thinking that fewer vaccines are needed (78.1%) were the top three factors influencing vaccine hesitancy. Conclusion This study urges promoting vaccine uptake through healthcare providers and combating vaccine misinformation on social media. Additionally, addressing safety concerns and misconceptions about vaccine necessity, and focusing on first-time parents, younger parents, and those with lower socioeconomic status are recommended strategies to improve vaccine uptake rates.

Medical and public health professionals' perceived facilitators and barriers of human papillomavirus (HPV) vaccination among African American adolescents in Shelby County, Tennessee

Human papillomavirus (HPV) infects nearly 85% of sexually active Americans during their lifetime, causing most cervical and five other cancers. Routine HPV vaccination is recommended for adolescents to prevent HPV-attributable cancers, but HPV vaccination coverage remains low, especially in Tennessee. In 2021, 54.6% of the population in Shelby County, Tennessee was Black or African American, reporting higher rates of new cervical cancer cases than other counties in Tennessee. While medical and public health professionals (HPs) play a critical role in promoting vaccination coverage, little is known about the factors HPs perceive to influence HPV vaccination for this population. This study sought to explore HPs' perceived facilitators and barriers of HPV vaccination among African American adolescents. Qualitative individual interviews with 26 HPs in Shelby County were conducted between October 2019 and February 2020. Interpretive content analysis of the interview data guided by the socio-ecological model revealed several important themes regarding the facilitators and barriers across the individual, interpersonal, and community levels. At the individual level, parental vaccine hesitancy emerged as a leading barrier to HPV vaccination, while appropriate education facilitated the vaccination. At the interpersonal level, a lack of strong provider recommendations impeded HPV vaccination, whereas improved communication skills with patients facilitated the vaccination. Finally, the community-level barriers included a lack of education and social/religious norms; the community-level facilitators included community outreach efforts. HPs should consider development of comprehensive community-based approaches that leverage the facilitators and barriers at multiple levels to increase HPV vaccination among African American adolescents in this region.

Addressing Vaccine Hesitancy Among Students and Families: Interventions for School Nurses

Vaccine hesitance is a public health issue that school nurses often address in practice. It has become even more prevalent during the coronavirus disease 2019 (COVID-19) pandemic. Vaccine compliance among schoolchildren is essential to the health of an entire community, given that many pediatric illnesses are vaccine-preventable. School nurses are involved in the promotion of vaccines in a school district, as they provide health education to students and families and are responsible for vaccine surveillance. Promoting vaccine compliance as a matter of public health can be challenging for school nurses, especially if a community holds strong beliefs regarding the necessity of pediatric vaccines. This article reviews the history of vaccine mandates, addresses challenges associated with vaccine compliance, and provides interventions school nurses can use when providing care to students and families regarding vaccine hesitancy. In following the nursing process, a school nurse is able to identify students missing vaccine(s) and evaluate for hesitancy, before implementing interventions that provide education to students and families. Several cost-efficient and accessible interventions can facilitate effective education and promote vaccine compliance. School nurses can forge trusting relationships and engage in compassionate dialogue to support vaccine compliance in the school.

Rapid Development and Testing of a COVID-19 Vaccine Curriculum for Pediatricians

BACKGROUND AND OBJECTIVES

As the coronavirus disease 2019 (COVID-19) pandemic evolves and vaccines become available to children, pediatricians must navigate vaccination discussions in the setting of rapidly changing vaccine recommendations and approvals. We developed and evaluated an educational curriculum for pediatricians to improve their knowledge about COVID-19 vaccines and confidence in communicating with patients and families about COVID-19 vaccines.

METHODS

Five institutions collaborated to develop an online educational curriculum. Utilizing the collaboration's multidisciplinary expertise, we developed a 3-module curriculum focused on the SARS-CoV-2 virus and vaccine basics, logistics and administration of COVID-19 vaccine, and COVID-19 vaccine communication principles. Surveys administered to clinician participants before and after completion of the curriculum assessed knowledge and confidence; a follow-up survey 1 month after the post-survey assessed persistence of initial findings.

RESULTS

A total of 152 pediatric providers participated; 72 completed both pre- and post-surveys. The median knowledge score improved from the pre-survey to the post-survey (79%-93%, P < .001). There was an increase in providers' confidence after completing the curriculum, which persisted in the follow-up survey. In the post-survey, 98% of participants had had the opportunity to discuss the COVID-19 vaccine with patients, and most clinicians reported that the modules decreased apprehension some or significantly.

CONCLUSIONS

This project demonstrates rapid and feasible deployment of a curriculum providing up-to-date information to front-line clinicians responsible for having complex conversations about COVID-19 vaccine decision-making. Clinicians who completed this curriculum had sustained increased confidence and decreased levels of apprehension when discussing the COVID-19 vaccine.

The Impact of a Revised National Childhood Immunization Schedule on Vaccination Defaulters

Immunization schedules affect community vaccine uptake rates, especially in children who have defaulted on their regular immunization timelines. In 2020, Singapore revised its National Childhood Immunization Schedule (NCIS) to incorporate two new combination vaccines: the hexavalent hepatitis, diphtheria, acellular pertussis, tetanus (DTaP), hemophilus influenzae b (Hib), inactivated poliovirus (IPV) (6-in-1), and the quadrivalent measles, mumps, rubella, and varicella (MMRV) vaccines, thus reducing the mean number of clinic visits and vaccine doses by two. Our database study aims to evaluate the impact of the 2020 NCIS on catch-up vaccination uptake rates in children at 18 and 24 months of age and the catch-up immunization rates of individual vaccines at two years. Vaccination data from two cohorts, in 2018 (n = 11,371) and in 2019 (n = 11,719), were extracted from the Electronic Medical Records. Catch-up vaccination rates increased by 5.2% and 2.6% in children on the new NCIS at 18 and 24 months, respectively. The uptake of individual 5-in-1 (DTaP, IPV, Hib), MMR, and pneumococcal vaccines increased by 3.7%, 4.1%, and 1.9% at 18 months. Reduced vaccination doses and visits in the new NCIS bring direct and indirect benefits to parents and promote vaccination adherence for their children. These findings highlight the importance of timelines in improving catch-up vaccination rates in any NCIS.

COVID-19 Maternal Prevention Behavior and Future Intention to Vaccinate for Children

BACKGROUND

During the COVID-19 pandemic, this study aimed to understand how a mother's current COVID-19 prevention behaviors were associated with the mother's future intention to vaccinate their children against COVID-19.

METHODS

Using a cross-sectional online survey, mothers who had at least one child between 3 and 15 years old were recruited. COVID-19 prevention behaviors evaluated were wearing a mask, appropriate coughing/sneezing, social distancing, staying home, and handwashing. Participants' age, marital status, race, educational level, incidence of COVID-19 infection in the household, healthcare worker in the household, and future intention to vaccinate children were obtained.

RESULTS

Among the 595 participants, 38.3% indicated they did not intend to use the COVID-19 vaccine for their children. Participants with no intention for vaccination had lower mean scores on wearing masks (p < 0.0001), social distancing (p < 0.0001), staying home (p < 0.0001), and handwashing (p < 0.05). The incidence of COVID-19 infection in the household was associated with a lower mean score of staying home (p < 0.01).

CONCLUSION

Our findings indicate that most mothers were compliant with the CDC recommended guidelines at the time of the survey. Mothers who indicated high adherence to prevention behaviors had a higher likelihood to consider vaccination for their children. Now that the COVID-19 vaccine is available for children as young as six months, healthcare providers need to be aware of the relationship between current prevention behaviors and future intention to vaccinate. They need to counsel parents appropriately with recommendations for children to keep practicing prevention behaviors.

COVID-19 vaccine communication and advocacy strategy: a social marketing campaign for increasing COVID-19 vaccine uptake in South Korea

Research evidence suggests that communication is a powerful tool for influencing public opinion and attitudes toward various health-related issues, such as vaccine reluctance, provided it is well-designed and thoughtfully conducted. In particular, social marketing techniques that alter the target audience's behaviors for the public good can substantially improve vaccine uptake if adopted as a communication strategy in immunization programs to counter public hesitancy. This study presents evidence from the Korean government's current coronavirus disease 2019 (COVID-19) vaccination campaign, which successfully applied a social marketing approach. By the end of August 2022, South Korea had achieved high vaccine coverage, with 94.8% of the population (12+) receiving a second dose, 71.3% a third dose, and a fourth dose drive currently underway. There are five crucial factors to consider when preparing official communication for an immunization program: (i) a high degree of proactiveness, (ii) credibility, (iii) fighting misinformation, (iv) emphasizing social norms and prosocial behavior, and (v) coherence. Although using social marketing strategies may not be successful in all circumstances, the lessons learned and current implementation in Korea suggest their efficacy in fostering vaccine acceptance. This study offers valuable insights for government agencies and global public health practitioners to develop effective targeted campaign strategies that enhance the target population's vaccination intention.

COVID-19 Vaccine Hesitancy among Economically Marginalized Hispanic Parents of Children under Five Years in the United States

Hispanic children in the US have high rates of COVID-19-related hospitalizations and deaths. Following FDA emergency approval, COVID-19 vaccination rates for young children under five years have been alarmingly low, especially in border states with significant Hispanic populations. This study identified social and cultural determinants of COVID-19 vaccine hesitancy among economically marginalized Hispanic parents of children under five. In 2022, following FDA approval, 309 Hispanic female guardians in US border states responded to an online survey assessing parental intent to vaccinate their child, demographic characteristics, COVID-19 health and vaccine beliefs, trust in traditional sources of health information, physician and community support, and acculturation to Anglo American norms. The majority (45.6%) did not intend to vaccinate their child or were unsure (22.0%). Kendall's tau-b indicated vaccine acceptance was negatively associated with COVID-19 specific and general vaccine distrust, belief the vaccine was unnecessary, time living in the U.S., and language acculturation (range tb = -0.13 to -0.44; p = 0.05-0.001) and positively related to trust in traditional resources, doctor's recommendation, child's age, household income and parent education (range tb = 0.11 to 0.37; p = 0.05-0.001). This research highlights the importance of COVID-19 vaccination public health strategies that draw on Hispanic cultural values, community partnerships and enhanced pediatrician communication regarding routine and COVID-19-specific vaccinations.

Reported Beliefs About COVID-19 Vaccines Among Unvaccinated Hispanic Adults Utilizing a Free Clinic in Orlando, Florida

BACKGROUND

Subgroups of the general population including Hispanic/Latinx individuals report higher rates of COVID-19 vaccine hesitancy than non-Hispanic White individuals. The purpose of this study was to identify factors that influence attitudes toward COVID-19 vaccines among unvaccinated Hispanic adults utilizing a free community clinic in Orlando, Florida, USA.

METHODS

From May 2021 to July 2021, we used convenience sampling to recruit 20 self-identified Hispanic adults who were unvaccinated to complete an individual, semi-structured interview. Interview questions were derived from constructs from the Health Belief Model. Interviews were audio-recorded, transcribed, translated (when necessary), and qualitatively analyzed using inductive content analysis to identify recurring themes.

RESULTS

Of the 20 participants in this study, 65% were female (n=13) and they ranged from 21 to 73 years of age (median age =42.5). We identified three primary themes in participant responses regarding their beliefs about COVID-19 vaccines. Primary theme 1: trust and clarity of COVID-19 vaccine information, with subthemes (1a) source trustworthiness, and (1b) clarity of COVID-19 vaccine information. Primary theme 2: personal contextual factors, with subthemes (2a) underlying health conditions, (2b) personal experiences with COVID-19, and (2c) immigration. Primary theme 3: lack of confidence, yet willingness to be vaccinated, with subthemes (3a) fear and distrust and (3b) willingness to be vaccinated. In summary, participants felt hesitant, although not completely opposed, to receiving COVID-19 vaccinations due to the information they gathered on vaccines from various sources received in the context of important personal factors (e.g., immigration, underlying health concerns, etc.).

CONCLUSIONS

Overcoming vaccine hesitancy in vulnerable populations such as the Hispanic communities may require addressing issues of message clarity through trusted sources while considering personal contextual factors. Healthcare professionals can begin by initiating discussions with patients to understand individual circumstances and concerns and provide information on COVID-19 vaccines that clarify areas of confusion.
