Stakeholders’ experiences with school-based immunization programs during the COVID-19 pandemic in the Canadian Maritimes: A qualitative study

BackgroundSchool-based immunization programs (SBIP) support access to routine vaccines for adolescents. Across Canada, the COVID-19 pandemic and subsequent public health measures affected SBIP and vaccine uptake. The objectives of this study were to explore 1.) stakeholders' experiences with SBIP and changes to programs during COVID-19 in Nova Scotia, Prince Edward Island and New Brunswick, and 2.) how the pandemic affected parents' and adolescents’ vaccine views. Study designSemi-structured interviews with decision makers, healthcare providers, teachers, parents and adolescents between February–August 2023. MethodsThe COM-B model and Theoretical Domains Framework informed interview guides. Deductive and inductive analyses saw participant quotes mapped to relevant model components and domains by two coders. Belief statements were generated within each stakeholder group then compared to identify themes and subthemes. ResultsParticipants (n = 39) identified five themes: 1) enablers to SBIP delivery, 2) barriers to SBIP delivery, 3) desired changes to SBIP delivery, 4) student anxiety, and 5) vaccination views and changes since the COVID-19 pandemic. Public health measures facilitated more space for clinics, as did taking smaller cohorts of students. School staff-healthcare provider relationships could help or hinder programs, particularly with high turnover in both professions during the pandemic. Adolescents played a passive role in vaccine decision making, with mothers often being the sole decision maker. We did not identify any changes in hesitancy towards routine vaccines since the pandemic. ConclusionsWe identified a range of barriers and enablers to SBIP, many of which were exacerbated by the pandemic. Efforts are needed to ensure SBIP and catch-up programming remains accessible for all adolescents to catch-up on missed vaccines before graduation. Parents and adolescents’ vaccination views suggest changes in vaccine coverage since the pandemic may be due to accessibility of services rather than vaccine hesitancy. Future research is needed to engage adolescents in their vaccine decisions.

"I'll take them another day": A qualitative study exploring the socio-behavioral complexities of childhood vaccination in urban poor settlements.

Despite improvement over recent decades, childhood vaccination uptake remains a concern across countries. The World Health Organization observed that over 25 million children missed out on one or more vaccines in 2021, with urban poor and other marginalized groups being the most affected. Given the higher risk of disease transmission and vaccine-preventable diseases (VPD) outbreaks across densely populated urban slums, identifying effective interventions to improve childhood vaccination in this vulnerable population is crucial. This study explored the behavioral and social factors influencing childhood vaccination uptake in urban informal settlements in Nairobi, Kenya. A grounded theory approach was employed to develop a theoretical account of the socio-behavioral determinants of childhood vaccination. Five focus group discussions (FGDs) were conducted with purposively sampled caregivers of children under five years of age residing in informal settlements. The Theory of Planned Behavior guided the structuring of the FGD questions. An iterative process was used to analyze and identify emerging themes. Thirty-nine caregivers (median age 29 years) participated in the FGDs. From the analysis, four main thematic categories were derived. These included attitude factors such as perceived vaccine benefits, cultural beliefs, and emotional factors including parental love. Additionally, subjective norms, like fear of social judgment, and perceived behavioral control factors, such as self-control and gender-based influences, were identified. Furthermore, a number of practical factors, including the cost of vaccines and healthcare providers attitude, also affected the uptake of vaccination. Various social, behavioral, cultural, and contextual factors influence caregiver vaccination decisions in urban poor settings. Community-derived and context-specific approaches that address the complex interaction between socio-behavioral and other contextual factors need to be tested and applied to improve the timely uptake of childhood vaccinations among marginalized populations.

Exploring Barriers and Facilitators to COVID-19 Vaccination in People Planning Pregnancy, Trying to Conceive, Pregnant, and Postpartum: A Mixed-Methods Study

Pregnant people are at higher risk of morbidity from COVID-19 infection, yet vaccine hesitancy remains prevalent. Our mixed-methods study utilised surveys and interviews to understand decision-making regarding COVID-19 vaccination surrounding pregnancy. The most trusted source of information was health care providers. Five themes relating to vaccination barriers and facilitators were identified: (1) COVID-19 vaccine-related policies; (2) pregnancy-specific considerations; (3) barriers, facilitators, and influencers to vaccination; (4) vaccination decisions based on personal health considerations; (5) attitudes toward COVID-19 and other vaccines. Our study underscores the importance of receiving high-quality information from a trusted source to increase vaccination.

How Technology, Health Information Seeking, and Socioeconomic Factors Are Associated With Coronavirus Disease 2019 Vaccination Readiness in Estonians Over 50 Years?

Despite the proven effectiveness of COVID-19 vaccines in preventing severe illness, many individuals, including older adults who are most susceptible to the virus, have opted against vaccination. Various factors could shape vaccination decisions, including seeking health information (HI). The internet is the primary source of HI today; however, older adults are often referred to as those missing out on digital benefits. The study explores the correlations between information and communication technology (ICT) use, online HI seeking, socioeconomic factors, and COVID-19 vaccination readiness among individuals aged 50 and above in Estonia. The survey data were gathered from 501 people aged 50 and older after the first lockdown in 2020. The outcomes revealed that vaccination readiness positively correlated with factors such as higher educational attainment, greater income, male gender, access to ICT, a readiness to employ digital technologies for health-related purposes, a greater demand for HI, and a higher frequency of seeking it online. There was some discrepancy in the preference of HI sources; for example, vaccination consenters preferred online versions of professional press publications and specific health portals. Based on the findings, it is advisable to encourage older adults to utilize the internet and new technology for health-related purposes. This practice expands the range of information sources available to them, ultimately enabling better decision-making regarding their health behaviors.

Trust in governments, public health institutions, and other information sources as determinants of COVID-19 vaccine uptake behavior in Japan

ObjectivesTrust in governments and public institutions as a determinant of public health outcomes has gained increased attention since the COVID-19 pandemic. Provided historically low confidence in vaccines in Japan, investigating the role of trust in information sources and actual COVID-19 vaccination uptake behavior will be invaluable for future vaccine promotion policymaking. Therefore, the objective of this study was to elucidate the determinants of COVID-19 vaccination uptake and evaluate the relationship between trust in different information sources and COVID-19 vaccination behavior in Japan. MethodsFor this study, we leveraged a longitudinal series of web-based surveys of 19,174 individuals in Japan conducted between 2021 and 2022 which asked questions regarding a wide range of sociodemographic and psychographic characteristics related to the COVID-19 pandemic. Determinant analysis for vaccination (at least one dose of a COVID-19 vaccine) was conducted via multiple logistic regression, and odds ratios (OR) with 95% confidence intervals (CI) were estimated. ResultsAfter adjustment for sociodemographic determinants of vaccine uptake, aggregate trust in the systems and institutions of vaccine approval (OR: 1.42, 95% CI: 1.30–1.56), and trust in information about the COVID-19 pandemic coming from government sources (OR: 1.27, 95% CI: 1.12–1.44) were found to be consistently powerful predictors of COVID-19 vaccination. Trust in media sources including traditional media (OR: 1.21, 95% CI: 1.07–1.36), and the internet (OR: 0.77, 95% CI: 0.66–0.89) had significant and opposing effects. ConclusionsOur findings support the broader hypothesis that trust in governments and public health institutions remains a powerful determinant for COVID-19 vaccine uptake in Japan. We also found that vaccination decision-making is a multifactorial process that includes the synthesis of trust in public institutions and media, and its interaction with psychosocial determinants such as prosociality and health literacy. We hope to apply this study's findings towards future vaccine programs for contagious diseases.

Information processing style and institutional trust as factors of COVID vaccine hesitancy

This study investigates the factors contributing to COVID vaccine hesitancy. Vaccine hesitancy has commonly been attributed to susceptibility to misinformation and linked to particular socio-demographic factors and personality traits. We present a new perspective, emphasizing the interplay between individual cognitive styles and perceptions of public health institutions. In January 2020, before the COVID-19 pandemic, 318 participants underwent a comprehensive assessment, including self-report measures of personality and clinical characteristics, as well as a behavioral task that assessed information processing styles. During 2021, attitudes towards vaccines, scientists, and the CDC were measured at three time points (February–October). Panel data analysis and structural equation modeling revealed nuanced relationships between these measures and information processing styles over time. Trust in public health institutions, authoritarian submission, and lower information processing capabilities together contribute to vaccine acceptance. Information processing capacities influenced vaccination decisions independently from the trust level, but their impact was partially mediated by authoritarian tendencies. These findings underscore the multifactorial nature of vaccine hesitancy, which emerges as a product of interactions between individual cognitive styles and perceptions of public health institutions. This novel perspective provides valuable insights into the underlying mechanisms that drive this complex phenomenon.

“It’s My Moral Responsibility to Protect Others!” Examining the Effects of Moral Framing and Message Format on Influenza Vaccination Attitude and Intention

ABSTRACT Vaccinations serve a dual purpose: safeguarding the vaccinated individuals while also preventing potential transmission to others. However, the pro-vaccine message has primarily emphasized the personal health risks and harms of not getting vaccinated, while rarely highlighting the moral responsibility of getting vaccinated to protect others. Guided by the Model of Intuitive Morality and Exemplars (MIME) along with the narrative persuasion framework, the current study conducted a 2 (moral framing: vaccination to protect oneself vs. protect others) X 2 (message format: statistical vs. narrative) between-subject online experiment to examine the effects of moral framing and message format on vaccination decision-making. The results revealed that individuals exposed to a pro-vaccine message framing vaccination as a moral responsibility to protect others from harm reported significantly higher levels of perceived moral responsibility and elevation, more positive attitudes toward the flu vaccine, and an increased intention to get vaccinated compared to a pro-vaccine message emphasizing vaccination for self-protection. Counterintuitively, presenting the moral responsibility of receiving the flu vaccine to safeguard others in a statistical format was discovered to be more effective in fostering favorable attitudes toward vaccination and increasing the intention to get vaccinated. This study offers a valuable insight: promoting vaccination as a moral duty could be a promising strategy for motivating individuals to get vaccinated.

Changing rules, recommendations, and risks: COVID-19 vaccination decisions and emotions during pregnancy

As COVID-19 vaccinations rolled out globally from late 2020, rules and recommendations regarding vaccine use in pregnancy shifted rapidly. Pre-registration COVID-19 vaccine trials excluded those who were pregnant. Initial Australian medical advice did not routinely recommend COVID-19 vaccines in pregnancy, due to limited safety data and little perceived risk of local transmission. Advice from local medical authorities changed throughout 2021, however, with recommendations and priority access during pregnancy. In Western Australia (WA), recommendations became requirements as the State government mandated vaccines for some workers, with brief availability of pregnancy exemptions. Through an examination of 10 in-depth interviews with WA pregnant women, we explore their decision-making and complex emotions regarding COVID-19 vaccinations, and how they balanced mandates, recommendations, and shifting considerations and perceptions of risk. Changing recommendations and rules—and media and popular interpretation and communications of these—led to confusion, including for medical professionals. Expectant parents had to negotiate the risks of COVID-19 disease, potential benefits and risks of vaccination, professional and personal costs of vaccine refusal, and interpret mixed medical advice. Our findings can inform the development and communication of public health policies and medical advice, and contribute to our understanding of bodily autonomy, risk, and decision-making beyond the pandemic.

Vaccination games and imitation dynamics with age structure combining perceived payoffs and media information

We propose an age-structured model based on game theory to investigate the dynamics of imitation in vaccination decisions. In our model, the rate at which individuals switch vaccination strategies is proportional to the perceived payoffs and media information. We analyze the existence and local stability of equilibria and demonstrate the possibility of Hopf bifurcation. Additionally, we establish the global stability of boundary equilibria and the persistence of the disease. The theoretical results are supported by numerical simulations. This model can be applied to study vaccination behavior among individuals of different ages and infectious disease stages, providing insights for the formulation of effective public health policies.

Racial (In)Equity in South Los Angeles-Community Centered Experiences with COVID-19 Syndemics.

To analyze community experiences involving COVID-19 vaccination access and equity in Black and Latina/o/x communities within South Los Angeles, using a socioecological framework. We conducted four virtual focus groups (n = 33 total participants) in 2021, with Black and Latina/o/x community members, community leaders, and community-based providers in South Los Angeles, a region highly impacted by the COVID-19 pandemic. We used a grounded theory approach to guide the analysis and generate data shaped by participant perspectives. Participants across groups consistently emphasized medical mistrust, fear/skepticism, misinformation, accessibility, and feelings of pressure and blame as factors influencing COVID-19 vaccination decisions. The need to address pandemic-related socioeconomic hardships in underresourced communities was equally highlighted. Findings show that building trust, providing tailored information, and continued investment into diversity and equity initiatives can support Black and Latino/a/x communities in making informed health decisions. Community-centered support services should address the economic, social, and structural impact of the pandemic on vulnerable communities. Furthermore, public health and policy efforts must prioritize funding to equip social and health care systems with infrastructure investment in racial and ethnic minority communities.

Exploring pre-pandemic patterns of vaccine decision-making with the 5C model: results from representative surveys in 2016 and 2018.

The 5C psychological antecedents of vaccination (Confidence, Complacency, Constraints, Calculation, and Collective Responsibility) facilitate understanding vaccination decisions in specific target groups as well as the general public's informational needs. This study aims to explain pre-pandemic vaccination behaviour (a) in general, (b) for specific vaccines such as influenza, and (c) for certain target groups (e.g. people over the age of 59years, parents, healthcare workers), using the 5C model and sociodemographic variables. The intention to get an influenza vaccination was also analysed for target groups. The 5C, self-reported vaccination behaviour and the intention to vaccinate were collected in two representative telephone surveys in Germany - one in 2016 (n1 = 5,012) and another in 2018 (n2 = 5,054). Parents, people over the age of 59years, chronically ill people, people with a migratory background, pregnant women and healthcare workers were target groups. Overall, the 5C model had higher explanatory power than sociodemographic variables. The pattern of vaccine hesitancy slightly differed between vaccinations and target groups. Confidence in safety and effectiveness was always a significant predictor. Complacency (the underestimation of disease risks) and Constraints were significant predictors as well. Calculation (of risks and benefits) was important for influenza vaccination intentions. This work builds an important benchmark for understanding potential changes in vaccine acceptance due to the pandemic. The benchmark can be used in research on potential effects of the pandemic on vaccination behaviours. Intervention designers can also use the results to understand specific audiences and their vaccination decisions.

Association between friends’ hesitancy and personal COVID-19 vaccine hesitancy among Chinese medical staff

ABSTRACT COVID-19 vaccine hesitancy remains problematic among healthcare workers. Social network influences may shape vaccine decision-making, but few studies have examined this in this critical workforce. We assessed the relationship between friends’ COVID-19 vaccination attitudes and personal hesitancy among Chinese healthcare personnel. In December 2022–January 2023, a cross-sectional online survey was conducted at a tertiary hospital in China using WeChat. Of the 1832 healthcare personnel who were invited to answer the structured questionnaire, 613 (33.5%) samples had valid data for data analysis. Logistic regression examined the association between friends’ hesitancy and participants’ own hesitancy, adjusting for confounders. Of 613 healthcare workers included, 266 (43.4%) were hesitant. Those with hesitant friends had 6.34 times higher adjusted odds of hesitating themselves versus those without hesitant friends (95% CI 2.97–13.52). Strong associations persisted across subgroups. Chinese healthcare workers’ COVID-19 vaccination hesitancy was highly influenced by perceived friends’ attitudes. Fostering pro-vaccine social norms through trusted peer networks could help promote vaccine acceptance in this critical workforce.

What factors influence the uptake of vaccinations amongst pregnant women following the Covid-19 pandemic: A qualitative study

BackgroundPregnant women and their unborn babies are at increased risk from serious complications, hospitalisation and death from infectious diseases. Vaccinations for influenza (flu), pertussis (whooping cough) and Covid-19 are available for free for pregnant women in the UK, but uptake of these repeatedly remains low. This qualitative study aimed to explore how pregnant women feel about these vaccinations, and what factors influence the uptake of vaccinations amongst pregnant women since the onset of the Covid-19 pandemic. MethodsPregnant women were recruited via two participating hospitals in one geographic area of the UK, and via one community group offering support to pregnant women from ethnic minorities. Semi-structured interviews were conducted remotely using telephone, were anonymised and transcribed, and analysed using thematic analysis. FindingsInterviews were conducted remotely with 43 pregnant women. The following themes were identified as influencing uptake of vaccinations amongst pregnant women: internal factors and beliefs, vaccination related factors, external influences and Covid-19 and changing perceptions of the pandemic. DiscussionFindings of this study increase awareness of some of the factors influencing vaccination decisions of pregnant women. It informs practice regarding healthcare professionals’ discussions with pregnant women about vaccinations, and future vaccination campaigns and interventions that are targeting an increase in vaccination uptake amongst this population.

Predicting future vaccination habits: The link between influenza vaccination patterns and future vaccination decisions among old aged adults in China

BackgroundAnnual influenza vaccination is crucially recommended for the elderly to maintain humoral immunity. Insufficient coverage requires us to understand the determinants of their influenza behaviors and how these patterns impact vaccination choices. MethodsData from 540 Beijing residents aged over 65 were collected through interviews, capturing vaccination history and sociodemographic details. Individual influenza vaccination records from 2016 to 2020 were obtained from China’s Immunization Information Systems. A latent class model identified three vaccination patterns. Multinomial logistic regression assessed relative risk ratios (RRRs) for vaccination based on sociodemographic factors. Vaccination patterns were used to predict future vaccination likelihood. ResultsThe analysis revealed three groups: sporadically vaccinated (63.33%), occasionally vaccinated (18.71%), and frequently vaccinated (17.96%). Factors associated with frequent vaccination included age over 70 (RRR = 2.81), lower income (RRR = 0.39), higher vaccine hesitancy (RRR = 3.10), multiple chronic conditions (RRR = 2.72), and rural residence (RRR = 2.48). The frequently vaccinated group was more likely to sustain regular vaccination habits in subsequent years compared to the occasionally vaccinated group. ConclusionsOnly 17.96% of Beijing’s older population exhibited a consistent influenza vaccination pattern. Older age, rural residency, and chronic diseases correlated with repeated influenza vaccination. Segmenting the population based on past vaccination behavior can aid in designing targeted interventions to improve vaccination rates.

Examining the role of community champions to promote vaccine uptake in under-served communities in the United Kingdom: Lessons from the COVID-19 pandemic

The COVID-19 pandemic has highlighted how ethnic minority groups are disproportionally affected by health crises and the potential for community engagement to provide equitable public health information and services. Policymakers, practitioners, and academics have presented community engagement as a way to improve the access and uptake of health services, including vaccination, but the role of community members for health promotion is rarely questioned. We examine ‘community vaccine champions’, who have been acting as advocates, promoting engagement among ethnic minority groups for COVID-19 vaccination in different communities across the United Kingdom. Our research explores how champions working with minoritised groups have experienced and confronted the challenges brought on by the pandemic. Participants were invited to participate in this study as they worked with or for the Black or South Asian community (i.e., community leader, faith leader, or a public or allied health professional) and were working or had worked to increase COVID-19 vaccine uptake. From April 2021 until May 2022, we conducted 12 semi-structured interviews lasting 45–60 min via video call. The interviews were inductively coded and analysed following a discourse approach to health communication, where a focus is made to draw out underlying messages and talking points.Our findings highlight the range of different types of champions, who have a variety of roles within their respective community groups. Champions proved adaptive in taking on new positions to promote vaccination, with limited training and preparation, and found that being ‘grassroots’ actors positioned them well to both address local needs and to help build trust between authorities and their communities. A major issue that champions found was the use of ethnic minority classifications and how to address misinformation. Classifications were seen as a problem in how relevant data was collected, as well as in assigning blame to certain groups. Champions also stressed the influence of media and social media misinformation on vaccine decision-making. Still, our informants cautioned taking action based on simplistic assumptions about how misinformation negatively affects vaccine uptake. We conclude by setting out the need for ongoing community support for health issues and the challenges of community engagement for vaccine promotion in a pandemic setting.

Understanding Vaccine Hesitancy Dynamics: Insights from Northern Mindanao, Philippines

Background & Aim: Amidst the ongoing COVID-19 pandemic, vaccine hesitancy persists, especially within specific demographics. This study delved into vaccine hesitancy among Northern Mindanao, Philippines, residents aged 20 to 64, aiming to understand factors shaping vaccination decisions. Employing the Health Belief Model, the research sought to dispel misconceptions and bolster vaccine uptake through evidence-based public health education and improved communication strategies. By examining socio-demographic variables like age, gender, education, religion, and vaccination status, the study informed targeted interventions for enhancing vaccine acceptance and bolstering community health outcomes. Methods: This study employed a quantitative, descriptive-correlational design and analyzed vaccine hesitancy factors among Northern Mindanao, Philippines residents aged 20 to 64. Stratified sampling ensured representative inclusion across age groups, with a sample size of 372 respondents. Statistical analyses, including F-tests and ANOVA, assessed hesitancy differences, while stringent adherence to data privacy regulations safeguarded participant confidentiality. Results: Among respondents, those aged 51 to 69 exhibited the highest vaccine hesitancy levels, particularly regarding uncertainty and knowledge about COVID-19 vaccines. However, no significant relationship was found between hesitancy levels and age or gender. Conversely, significant disparities in hesitancy were observed concerning educational attainment, religion, and vaccination status. Conclusion: While age, gender, education, and religion are associated with varying levels of COVID-19 vaccine hesitancy, none singularly determine hesitancy. Enhanced education and knowledge about vaccines correlate with decreased hesitancy, emphasizing the necessity of targeted education initiatives. However, significant hesitancy disparities based on vaccination status underscore the ongoing challenge of addressing hesitancy despite reassurances about vaccine safety. Recommendation: Implementing tailored educational programs that address specific concerns related to demographic factors is recommended as a crucial strategy for reducing COVID-19 vaccine hesitancy

“Your child will have a bird brain!”: Vaccination choices and stigma among vaccine enquirers in Sweden: A qualitative study

BackgroundSubstantial research has explored reasons for vaccination delay or refusal. However, little attention has been paid to the process and implications of the choices. The aim of this research was to understand parent's vaccination choices and implications of their choices through the lens of the concept of stigma and health behaviours. MethodsThis is a qualitative study drawing on five focus group discussions and 17 in-depth interviews. Data was collected in an area South of Stockholm that has experienced lower rates of vaccination and is home to some people who are partly inspired by anthroposophical values. The data was analysed following reflexive thematic analysis. Results(1) Vaccine enquirers make an informed decision about their vaccination choices. They negotiate different sources, question science, ask for more information and are largely content with their decision. (2) Values and norms influence vaccination decisions; these include anthroposophical health beliefs, and they partly influence the way in which risk is balanced. Trust influences vaccination decisions but trust expresses itself in complex ways. (3) Vaccination related stigma; expressed through fear of being labelled, conflicts with family and friends, feeling lonely with the decision, and avoidance to discuss vaccination choice. (4) Vaccination related stigma was found in the healthcare setting too, expressed by participants working in the health system as well as parents who experienced disrespect and labelling when expressing vaccine choices or seeking healthcare with an unvaccinated child. Participants describe their community as a safe haven where different vaccination choices are respected. ConclusionThe study found that vaccine enquirers are individuals who make an active choice to delay or decline vaccination. They are not uncertain or hesitant but rather consider themselves well-informed. The study also found different forms of stigma related to vaccination choices. Further research may be helpful to understand implications of vaccination related stigma on health and other vaccination decisions.

Understanding patient perspectives on vaccine decision making in adults with autoimmune bullous diseases: a qualitative study.

Patients with autoimmune bullous diseases are at an increased risk of infection, both from the underlying skin disease and from immunosuppressive treatments. Limited information is available on vaccine beliefs and behaviors in dermatology patients and adults with autoimmune bullous diseases in particular. To understand vaccine decision making, identify perceived risks and benefits of vaccinations, and discuss individual experiences in patients with autoimmune bullous diseases in the United States. A qualitative study was performed utilizing semi-structured interviews, and analysis was conducted on NVivo. Patterns were identified in the coded data, and representative quotations were recorded for each major theme. Interviews were conducted between February 15, 2022 and September 15, 2022. Twenty patients with a diagnosis of bullous pemphigoid, mucous membrane pemphigoid, pemphigus vulgaris, or pemphigus foliaceous were interviewed. Of the 20 participants, 14 (70%) were female, with a mean (SD, range) age of 64.8 (13.2, 34-83) years. Key themes that emerged from qualitative analysis of the interviews included patient concerns regarding their increased susceptibility to infection, potential exacerbation of skin disease following vaccination, and the effect of immunosuppressive medications on humoral response to vaccines. Lack of appointment availability, difficulty accessing vaccines, and cost were commonly identified barriers to vaccination. These findings provide valuable knowledge for dermatologists in regard to providing counseling specific to patient concerns and to improve communication surrounding vaccination in the dermatology setting.

Diverse Parents Decision-Making to Vaccinate Their Child under Five Attending Childcare Programs.

Background: On 18 June 2022, Moderna and Pfizer-BioNTech COVID-19 vaccines were authorized under an Emergency Use Authorization by the United States Food and Drug Administration to prevent severe coronavirus disease in children six months to four years of age. Despite approval of the COVID-19 vaccinations for young children, there remain ongoing challenges reaching widespread coverage due to parental decision-making. Parental decision-making plays a pivotal, yet understudied, role governing vaccine adoption among this priority demographic. Methods: This cross-sectional analysis examined COVID-19 vaccine intentions for 320 predominately Hispanic parents of two to five-year-olds attending Miami-Dade County childcare programs in Florida USA, several months following the June 2022 emergency authorization. Parent's self-reported survey data encompassed vaccine choices and rationales, social determinants of health, and parent immigrant status. Data analyses illustrate the associations between parent decision-making and these variables. Regression modeling and tests of independence identified predicting factors for parental vaccine decision-making. Results: Only 25% of parents intended to vaccinate their young child, while 34% resisted and 41% felt unsure, despite 70% personal vaccination rates. Household income under $25,000, identifying as a migrant, or testing COVID-19-positive significantly predicted unsure decision-making. The majority of hesitant groups expressed concerns around side effects (20%), safety (2.9%), and sufficiency of vaccine knowledge (3.3%). Conclusions: In this sample, the predominance of parents were unsure and resistant rather than accepting of having their child vaccinated despite emergency approval of the pediatric vaccine. Associations and predictive factors are examined.

Perspectives in the Development of Tools to Assess Vaccine Literacy.

Vaccine literacy (VL) is the ability to find, understand, and evaluate vaccination-related information to make appropriate decisions about immunization. The tools developed so far for its evaluation have produced consistent results. However, some dimensions may be underestimated due to the complexity of factors influencing VL. Moreover, the heterogeneity of methods used in studies employing these tools hinders a comprehensive understanding of its role even more. To overcome these limitations, a path has been sought to propose new instruments. This has necessitated updating earlier literature reviews on VL and related tools, exploring its relationship with vaccine hesitancy (VH), and examining associated variables like beliefs, attitudes, and behaviors towards immunization. Based on the current literature, and supported by the re-analysis of a dataset from an earlier study, we propose a theoretical framework to serve as the foundation for creating future assessment tools. These instruments should not only evaluate the psychological factors underlying the motivational aspect of VL, but also encompass knowledge and competencies. The positioning of VL in the framework at the intersection between sociodemographic antecedents and attitudes, leading to behaviors and outcomes, explains why and how VL can directly or indirectly influence vaccination decisions by countering VH and operating at personal, as well as at organizational and community levels.
