Is vaccine confidence an unexpected victim of the COVID-19 pandemic?

"The needle is already ready to go": communities' and health care professionals' perceptions of routine vaccination in Nunavik, Canada

Inuit living in the northern region of Nunavik continue to experience significant health inequalities, which are rooted in colonialism that still have repercussions on their health-related perceptions and practices, including vaccination. This study aimed to explore the perceptions and determinants of routine vaccination among the Inuit of Nunavik by describing factors influencing vaccination decisions from the perspective of community members and health professionals. Semi-structured interviews focusing on the perception of vaccination and experience with vaccination and health services were conducted with 18 Inuit and 11 non-Inuit health professionals. Using the socio-ecological model, factors acting at the community and public policy (e.g. rumours and misinformation about vaccination, language barrier), organisational (e.g. complexity of the vaccination process, staff turnover, lack of specialised vaccination workers and interpreters), and intrapersonal and interpersonal (e.g. past experiences with vaccination, vaccine attitudes, social norms) levels were identified as having an impact on vaccination decisions. Improving vaccination coverage in Nunavik requires a more global reflection on how to improve and culturally adapt the health care and services offered to the Inuit population.

Watchful, skeptics, and system distrusters: Characteristics associated with different types of COVID-19 vaccine hesitancy among U.S. working-age adults

COVID-19 vaccine hesitancy is complex, with adults identifying various reasons for not getting vaccinated. Using data from the 2022 National Wellbeing Survey on 7612 U.S. adults aged 18-64, we identified how age, race/ethnicity, sex, marital status, education, income, employment status, partisanship, and metropolitan status are associated with COVID-19 vaccination status and three non-mutually exclusive types of vaccine hesitancy: 1) watchful, concerned about vaccine side effects and efficacy; 2) skeptics, distrust the vaccine, and 3) system distrusters, distrust government. A third of respondents overall (N = 2643) had not received at least one dose at the time of the survey. Among respondents who were not vaccinated, 67 % are classified as watchful, 53 % are skeptics, and 32 % are system distrusters. Results from logistic regression show that concerns about side effects and safety (watchfulness) appear to be major drivers for not getting vaccinated among females and among non-Hispanic Black and unmarried adults, whereas skepticism and distrust appear to be more important barriers among ages 25-44. All three types of hesitancy appear to be important contributors to lower vaccination uptake among low-income, low-education, and unemployed adults, and among individuals who voted for Donald Trump in the 2020 election (with skepticism and distrust being most endorsed by this group). Findings suggest that universal messaging and intervention strategies are unlikely to be effective in reducing vaccine hesitancy. Different messages, messengers, and tactics must be used with different groups.

First vaccine confidence and access index in Argentina: Comparison of results from 2019 to 2022

In this article, we present and empirically illustrate two concepts about vaccines and the way they are perceived by the Argentinean population and the easiness in accessing vaccination in developing countries. First, we focus on the perceptions of people about vaccines in general and develop a confidence index, and second, we analyze barriers to vaccination, measuring the burden citizens have when they intend to receive immunization (or as caretakers, trying to comply with the vaccination calendar of children and adolescents): for this second concept, we develop an access index. The data comes from representative annual surveys from Argentina from 2019 until 2022 (each one with approximately 7000 responders), which allows us to describe trends and check for changes in the confidence in vaccines and barriers towards vaccination. We find high confidence in vaccines in Argentina, although there is a "structural break" in the confidence for all years after 2020. Because we changed the questionnaire and methodology regarding the access to vaccines index in 2022, the discussion focuses on the cross-section of 2022, observing that barriers to vaccination tend to affect less educated caretakers.

"Spine to the future"-A narrative review of anatomy engagement

Anatomy has been integral to medical and health education for centuries, it has also had a significant role in wider public life, as an educational resource, a link to their health, and also as a darker deterrent. Historically, public engagement in anatomy is hallmarked by public dissections of convicted criminals across the globe. Artists, specifically non-medical men, such as Leonardo da Vinci, are reported to have participated in public dissection. Dissection would later rekindle public interest in anatomy as graverobbing led to the reform and regulation of anatomy in many countries. In recent years, there has been growing interest from the public in learning more about their bodies as health and well-being become of paramount importance, particularly following the COVID-19 pandemic. Anatomy sits in a prime position to direct and instigate conversations around health, well-being, and body image. Every human on earth possesses a perfect resource to look at and learn about. Models, art-based anatomical activities, and crafts provide active learning opportunities for the wider public around anatomy. Most recently, apps, games, and extended reality provide novel and insightful learning opportunities for the public relating to the body. Finally, training and resources must also be made available from institutions and professional bodies to anatomists to enable them to deliver engagement in an already congested and educationally heavy schedule. This resurgence of interest in anatomical public engagement sees anatomy re-enter the public spotlight, with more appropriate resources and educational settings to offer engagement with the aim of benefiting the public.

Missed opportunities for human papillomavirus vaccination using Iowa's Immunization Registry Information System

PURPOSE

Adolescent human papillomavirus (HPV) vaccination rates continue to remain lower than other adolescent vaccines, both nationwide and in Iowa. This study examined predictors of missed opportunities for first-dose HPV vaccine administrations in Iowa in order to conduct more targeted outreach and improve adolescent HPV vaccine uptake.

METHODS

A retrospective study was conducted to identify predictors of missed opportunities for first-dose HPV vaccination in Iowa adolescents using Iowa's Immunization Registry Information System. The study population included 154,905 adolescents aged 11-15 years between 2019 and 2022. Missed opportunity for first-dose HPV vaccination was defined as a vaccination encounter where an adolescent received a Tdap and/or MenACWY vaccine but did not receive the first-dose HPV vaccine during the same encounter.

FINDINGS

Over a third of the study population experienced a missed opportunity for HPV vaccination between 2019 and 2022. Missed opportunity for vaccination was most common among individuals living in a rural county (aOR = 1.36), underinsured adolescents (aOR = 1.74), males (aOR = 1.12), teens 13-15 years of age (aOR = 1.76), and White race and non-Hispanic ethnicity.

CONCLUSION

This study builds on previously reported predictors of missed opportunity for HPV vaccination in adolescents. Increased understanding of provider needs and barriers to administering HPV vaccination and further analysis of how the Vaccines for Children Program can play a role in HPV vaccination uptake is necessary to improve HPV vaccination rates among adolescents in Iowa and more specifically in rural communities.

The Impact of the Coronavirus Pandemic on Vaccination Coverage in Latin America and the Caribbean

BACKGROUND

Routine vaccination coverage in Latin America and the Caribbean declined prior to and during the coronavirus pandemic. We assessed the pandemic's impact on national coverage levels and analyzed whether financial and inequality indicators, immunization policies, and pandemic policies were associated with changes in national and regional coverage levels.

METHODOLOGY

We compared first- and third-dose coverage of diphtheria-pertussis-tetanus-containing vaccine (DTPcv) with predicted coverages using time series forecast modeling for 39 LAC countries and territories. Data were from the PAHO/WHO/UNICEF Joint Reporting Form. A secondary analysis of factors hypothesized to affect coverages during the pandemic was also performed.

RESULTS

In total, 31 of 39 countries and territories (79%) had greater-than-predicted declines in DTPcv1 and DTPcv3 coverage during the pandemic, with 9 and 12 of these, respectively, falling outside the 95% confidence interval. Within-country income inequality (i.e., Gini coefficient) was associated with significant declines in DTPcv1 coverage, and cross-country income inequality was associated with declines in DTPcv1 and DTPcv3 coverages. Observed absolute and relative inequality gaps in DTPcv1 and DTPcv3 coverage between extreme country quintiles of income inequality (i.e., Q1 vs. Q5) were accentuated in 2021, as compared with the 2019 observed and 2021 predicted values. We also observed a trend between school closures and greater-than-predicted declines in DTPcv3 coverage that approached statistical significance (p = 0.06).

CONCLUSION

The pandemic exposed vaccination inequities in LAC and significantly impacted coverage levels in many countries. New strategies are needed to reattain high coverage levels.

The 5 C model and Mpox vaccination behavior in Germany: a cross-sectional survey

BACKGROUND

Due to the authorization of the Mpox vaccines, we aimed to identify determinants of the intention to get vaccinated, actively trying to receive vaccination, and for successfully receiving a vaccination in Germany employing the 5 C model of vaccination readiness.

METHODS

Data stem from a cross-sectional online survey that was available online from August 13, 2022 to August 31, 2022. To assess the influence of the 5 C Model on vaccination behavior, we conducted a multinomial logistic regression.

RESULTS

3,338 participants responded to the survey, with 487 already vaccinated and 2,066 intending to receive a vaccination. Confidence and collective responsibility were positively associated with intention to get vaccinated, while complacency was negatively correlated. A higher score on the calculation scale increased the odds of intention to receive vaccination but not with actively having tried to receive a vaccination. Fewer perceived constraints were associated with higher odds to be vaccinated. Patients in practices that focus on HIV treatment were more likely to intend to get vaccinated, to have tried to get vaccinated and to be vaccinated, regardless of indication. While level of education had no impact, having an indication to get vaccinated was a strong predictor of vaccination behavior in all groups.

CONCLUSION

Future vaccination campaigns should aim to reduce specific constraints of the target group and make vaccines widely available in primary care institutions beyond HIV-focused practices.

The Uptake of Pneumococcal and Seasonal Influenza Vaccinations Based on Perceptions and Attitudes Toward the COVID-19 Vaccine Among Patients With Diabetes

Objective In this study, we aimed to assess the rates of pneumococcal and seasonal influenza vaccinations among elderly and nonelderly diabetes patients and examine their perceptions and attitudes toward the coronavirus disease 2019 (COVID-19) vaccine. Methods A single-center study was conducted among patients with diabetes, employing a structured survey encompassing sociodemographic data, vaccination records, and the COVID-19 vaccine perception and attitude scale. Results Among the 280 diabetes patients in our study, the vaccination rates for COVID-19, seasonal influenza, and pneumococcal vaccines were 96.1%, 16.8%, and 17.5%, respectively. A higher cumulative dosage of the COVID-19 vaccine was associated with older age (r = 0.463; p<0.001), increased safety score (r = 0.479; p<0.001), and lower conspiracy theory score (r = -0.336; p<0.001). Participants who had received COVID-19 and influenza vaccines were observed to have significantly higher safety scores related to COVID-19 vaccines (p<0.001; d = 2.381 and p = 0.008; d = 0.525, respectively). Notably, vaccination rates for influenza and pneumococcus were significantly different between nonelderly and elderly patients (8.7% vs. 29.6%; p<0.001 and 13.4% vs. 24.1%; p = 0.022). Elderly patients with diabetes were 3.3 times more likely to receive the influenza vaccine than nonelderly participants [odds ratio (OR) = 3.319; 95% confidence interval (CI) = 1.592 - 6.920; p = 0.001] and had a higher safety score related to COVID-19 vaccines (OR = 1.076; 95% CI = 1.011 - 1.146; p = 0.021). Conclusions Both influenza and pneumococcal vaccination rates were below the desired targets in this study. The vaccination rates among the nonelderly diabetes population suggest that this group may be more likely to neglect to receive vaccination compared to the elderly diabetes population. The association between vaccination rates and post-pandemic safety perceptions highlights the critical need to implement public health strategies specifically designed to address and improve safety-related information dissemination.

Parental intention, attitudes, beliefs, trust and deliberation towards childhood vaccination in the Netherlands in 2022: Indications of change compared to 2013

BACKGROUND

Vaccine uptake within the Dutch National Immunisation Programme (NIP) has slightly declined since the COVID-19 pandemic. We studied psychosocial factors of vaccine uptake, namely parental intention, attitudes, beliefs, trust and deliberation (i.e., self-evidence), before (2013) and two years into the pandemic (2022).

METHODS

In 2022 and 2013, parents with a young child (aged < 3.5 years) participated in online surveys on vaccination (n = 1000 and 800, (estimated) response = 12.2 % and 37.2 %, respectively). Psychosocial factors were measured on 7-point Likert scales. Multivariate logistic regression analysis was used to study differences between parents in 2022 and 2013 in 'negative' scores (≤2) of psychosocial factors.

RESULTS

In both 2022 and 2013, most parents with a young child expressed positive intention (2022 = 83.1 %, 2013 = 87.0 %), attitudes (3 items: 2022 = 66.7 %-70.9 %, 2013 = 62.1 %-69.8 %) and trust (2022 = 51.8 %, 2013 = 52.0 %) towards the NIP and considered vaccinating their child as self-evident (2022 = 57.2 %, 2013 = 67.3 %). Compared to parents in 2013, parents in 2022 had significantly higher odds of reporting negative attitudes towards vaccination (3 items combined: OR = 2.84, 95 % CI = 1.09, 7.37), believing that vaccinations offer insufficient protection (OR = 4.89, 95 % CI = 3.19, 7.51), that the NIP is not beneficial for the protection of their child's health (OR = 2.23, 95 % CI = 1.15, 4.35), that vaccinating their child does not necessarily protect the health of other children (OR = 2.24, 95 % CI = 1.16, 4.33) or adults (OR = 2.22, 95 % CI = 1.32, 3.75) and that vaccinations could cause severe side effects (OR = 2.20, 95 % CI = 1.35, 3.58), preferring natural infection over vaccination (OR = 3.18, 95 % CI = 2.24, 4.51) and reporting low trust towards the NIP (OR = 1.73, 95 % CI = 1.08, 2.79).

CONCLUSIONS

Although most parents had positive intention, attitudes and trust towards vaccination and perceived vaccinating their child as self-evident, proportions of parents with negative scores were slightly larger in 2022 compared to 2013. Monitoring these determinants of vaccine uptake and developing appropriate interventions could contribute to sustaining high vaccine uptake.

High vaccine confidence and strong approval of the mandatory immunization schedule among Bulgarian general practitioners in 2022

In a context of recently decreasing childhood immunization coverage and low uptake of COVID-19 vaccines in Bulgaria, this study measures vaccine hesitancy among general practitioners (GPs) in the country, as they are central to forming patients' attitudes. In 2022, a face-to-face survey was conducted through a simple random sample from an exhaustive national database of Bulgarian GPs. This study measured attitudes on vaccine importance, safety, and effectiveness, and attitudes toward the Bulgarian immunization schedule. Information was collected on demographic and GP practice characteristics and possible predictors of vaccine confidence in order to test for associations with attitudes toward immunization. GP attitudes toward vaccines and the immunization schedule in Bulgaria were generally positive. Among 358 respondents, 351 (98%,95%CI96-99%) strongly agreed/agreed that vaccines are important, 352 (98%,95%CI96-99%) that vaccines are effective, and 341 (95%,95%CI93-97%) that vaccines are safe. 347 respondents (97%,95%CI95-98%) affirmed that "it's good that vaccines from the children's immunization schedule are mandatory", and 331 (92%,95%CI89-95%) agreed with the statement "Bulgaria's childhood immunization has my approval". Trust in information from official institutions was among the strongest predictors of vaccine confidence. Respondents' vaccine confidence levels are within the ranges reported by GPs in other European countries and above those reported within the general Bulgarian population. GPs' vaccine confidence is highly associated with trust in official institutions. It is important to maintain trust in official institutions and to support GPs in communicating vaccine knowledge with patients so that vaccine hesitancy in the general population is countered.

Identifying reasons for non-acceptance of influenza vaccine in healthcare workers: an observational study using declination form data

BACKGROUND

Healthcare workers are sometimes required to complete a declination form if they choose not to accept the influenza vaccine. We analysed the declination data with the goal of identifying barriers to vaccination uptake across seasons, staff groups, and pre- and post- arrival of COVID-19.

METHODS

Reasons for declining the vaccine were gathered from N = 2230 declination forms, collected over four influenza seasons, 2017/2018, 2018/2019, 2019/2020 and 2020/2021, from a single health board in the UK. Reasons were classified according to ten categories and the resulting distribution analysed across year and staff groups. A further analysis considered the two most prevalent categories in more detail.

RESULTS

Fear of adverse reactions and Lack of perception of own risk were identified as primary reasons for not accepting the vaccine across time and across staff groups. However, there was no evidence that Lack of concern with influenza, or Doubts about vaccine efficacy was prevalent, contrary to previous findings. Overall, reasons fitted a pattern of underestimating risk associated with influenza and overestimating risk of minor adverse reactions. There were also differences across years, χ2(24) = 123, p < .001. In particular, there were relatively fewer Lack of perception of own risk responses post-COVID-19 arrival than before, χ2(8) = 28.93, p = .002.

CONCLUSION

This study shows that data collected from declination forms yields sensible information concerning vaccine non-acceptance without the difficulties of retrospective or pre-emptive reasoning suffered by questionnaires. Our findings will aid messaging campaigns designed to encourage uptake of the influenza vaccine in healthcare workers. In particular, we argue for an approach focused on risk perception rather than correction of straightforward misconceptions.

Pediatricians' perspectives on COVID-19 and HPV vaccine hesitancy

Rises in parental vaccine hesitancy, observed during the COVID-19 pandemic, threaten public health. This is especially concerning for vaccines not typically required for school-entry, such as the vaccines for COVID-19 and human papillomavirus (HPV), both of which also have much lower rates of completion compared to other adolescent vaccines. Pediatricians are well-positioned to address vaccine hesitancy and can offer insights into parents' perspectives in this area. There is evidence that pediatricians' sharing their own vaccine stories may help to address parents' concerns; yet we have little information on pediatricians' or their children's COVID-19 vaccine uptake. To address these gaps, we conducted a cross-sectional survey about Massachusetts pediatricians' behaviors and perspectives on vaccines that face significant resistance: HPV and COVID-19 vaccines. A total of 144 people initiated the survey, and 109 participants were eligible and completed the survey. Participants reported high levels of COVID-19 vaccine uptake for themselves (97%) and their children (98%). Similarities in parents' resistance toward both vaccines were identified: fear of side effects; general vaccine resistance. Pediatricians reported a rise in vaccine hesitancy since the beginning of the COVID-19 pandemic. Future research should focus on identifying strategies to build overall vaccine confidence and streamline these efforts for pediatricians.

Pre-travel vaccine information needs, attitudes, drivers of uptake and the role for decision aids in travel medicine

BACKGROUND

Many travellers do not receive vaccines pre-travel. Tools such as vaccine decision aids could support informed vaccine decision-making. We aimed to characterise Australians' pre-travel vaccine attitudes, behaviours and information needs and examine the role for decision aids in travel medicine.

METHODS

Online cross-sectional survey of Australian adults in December 2022. We included questions on demographics, pre-travel health-seeking behaviour, and information needs. We measured vaccine confidence (Vaccine Confidence Index Index) and used hypothetical disease scenarios to evaluate behavioural and social drivers of vaccination. We used multivariable logistic regression models to identify predictors of vaccine uptake and thematically analysed free-text responses.

RESULTS

We received complete survey responses from 1223/1326 Australians (92% response rate). Amongst those reporting previous overseas travel, 67% (778/1161) reported past pre-travel health encounter(s) and 64% (743/1161) reported past pre-travel vaccination. Half (50%) strongly agreed that vaccines were important for their health; fewer strongly agreed that vaccines were safe (37%) and effective (38%). In multivariable analyses, past pre-travel vaccine uptake was associated with increasing age (OR = 1.17 [95% CI 1.08-1.27] p < 0.001 per ten-year increase) and travel to higher-risk destinations (OR = 2.92 [2.17-3.93] p < 0.001); travellers visiting friends and relatives (VFRs) were less likely to have received pre-travel vaccines (OR = 0.74 [0.56-0.97] p = 0.028). Predictors for wanting vaccination against hypothetical diseases included past pre-travel vaccination (Disease X: OR 2.60 [1.91-3.56] p < 0.001) and confidence in vaccine safety (Disease X: OR 7.18 [5.07-10.18], p < 0.001); past VFR travel was predictive of not wanting vaccination (Disease X: OR 0.72 [0.52-1.00], p = 0.049). Most (63%) were interested in using a vaccine decision aid, generally together with a trusted health professional.

CONCLUSIONS

Health professionals play an important role in supporting pre-travel vaccine decision-making. However, our findings indicate that reliable, accurate and engaging digital resources, such as decision aids, could support travellers to make informed pre-travel vaccine decisions.

Spillover effects of the COVID-19 pandemic on attitudes to influenza and childhood vaccines

The current study sought to determine whether public perceptions of other vaccines and diseases than COVID-19 have been impacted by the COVID-19 pandemic. We longitudinally examined whether there had been a change from before the COVID-19 pandemic to during the pandemic in: (a) influenza vaccination behaviour and intentions; (b) the perceived benefit of childhood vaccines and influenza vaccines; (c) the perceived safety of childhood vaccines and influenza vaccines; (d) the perceived severity of measles and influenza; and (e) trust in healthcare professionals in two samples of Finnish adults (N = 205 in Study 1 and N = 197 in Study 2). The findings showed that during the pandemic, more people than before had received or wanted to receive the influenza vaccine. The respondents also believed that influenza was more dangerous during the pandemic and that vaccinations were safer and more beneficial. On the other hand, for childhood vaccines only perceived safety increased. Finally, in one of the studies, people had more confidence in medical professionals during the pandemic than they had before. Together, these findings imply a spillover of the COVID-19 pandemic on how people view other vaccines and illnesses.

What accounts for the variation in COVID-19 vaccine hesitancy in Eastern, Southern and Western Europe?

In the wake of mass COVID-19 vaccination campaigns in 2021, significant differences in vaccine skepticism emerged across Europe, with Eastern European countries in particular facing very high levels of vaccine hesitancy and refusal. This study investigates the determinants of COVID-19 vaccine hesitancy and refusal, with a focus on these differences across Eastern, Southern and Western Europe. The statistical analyses are based on individual-level survey data comprising quota-based representative samples from 27 European countries from May 2021. The study finds that demographic variables have complex associations with vaccine hesitancy and refusal. The relationships with age and education are non-linear. Trust in different sources of health-related information has significant associations as well, with people who trust the Internet, social networks and 'people around' in particular being much more likely to express vaccine skepticism. Beliefs in the safety and effectiveness of vaccines have large predictive power. Importantly, this study shows that the associations of demographic, belief-related and other individual-level factors with vaccine hesitancy and refusal are context-specific. Yet, explanations of the differences in vaccine hesitancy across Eastern, Southern and Eastern Europe need to focus on why levels of trust and vaccine-relevant beliefs differ across regions, because the effects of these variables appear to be similar. It is the much higher prevalence of factors such as distrust of national governments and medical processionals as sources of relevant medical information in Eastern Europe that are relevant for explaining the higher levels of vaccine skepticism observed in that region.

Determinants of COVID-19 vaccine acceptance and access among people experiencing homelessness in Germany: A qualitative interview study

Introduction

People experiencing homelessness face lower life expectancy, higher prevalence of somatic and mental diseases and a more difficult access to healthcare compared to people in secure living. During the COVID-19 pandemic transmission rates were higher among people experiencing homelessness and preventive public health measures were not properly adapted to the specific needs of people experiencing homelessness. Thus, goal of our study was understanding the determinants of acceptability and access of the COVID-19 vaccine.

Materials and methods

We conducted a qualitative interview study with twenty guideline interviews with adult people currently experiencing homelessness in Berlin, Germany (August 2021 - April 2022). Participants were approached in a purposive sampling strategy. The interviews were analyzed with qualitative content analysis according to Mayring.

Results

Acceptance and attitude toward the COVID-19 vaccine is influenced by confidence in the vaccine as well as in the political and healthcare system, the individual COVID-19 risk perception and sense of collective responsibility. Overall, the acceptance of the vaccine was high among our participants. Facilities offering low threshold COVID-19 vaccines for people experiencing homelessness were perceived as helpful. Language barriers and the need for identity documents were major barriers to access the COVID 19 vaccine.

Discussion

People experiencing homelessness are a marginalized and vulnerable group often underrepresented in the public and scientific discourse. During the COVID-19 pandemic, preventive public health measures, including the COVID-19 vaccine, failed to consider specific needs of people experiencing homelessness. Multidimensional strategy to enhance inclusive healthcare are needed to improve access and to reduce discrimination and stigmatization.
