Believing in science: Linking religious beliefs and identity with vaccination intentions and trust in science during the COVID-19 pandemic.

Despite evidence supporting numerous scientific issues (e.g. climate change, vaccinations) many people still doubt the legitimacy of science. Moreover, individuals may be prone to scepticism about scientific findings that misalign with their ideological beliefs and identities. This research investigated whether trust in science (as well as government and media) and COVID-19 vaccination intentions varied as a function of (non)religious group identity, religiosity, religion-science compatibility beliefs, and/or political orientation in two online studies (N = 565) with university students and a Canadian community sample between January and June 2021. In both studies, vaccination intentions and trust in science varied as a function of (non)religious group identity and beliefs. Vaccine hesitancy was further linked to religiosity through a lack of trust in science. Given the ideological divides that the pandemic has exacerbated, this research has implications for informing public health strategies for relaying scientific findings to the public and encouraging vaccine uptake in culturally appropriate ways.

Factors associated with HPV vaccine acceptability and hesitancy among Black mothers with young daughters in the United States.

Introduction: Compared to other-race peers, Black women are disproportionately impacted by human papillomavirus [HPV] infection, related health outcomes, and cervical cancer mortality as a result of suboptimal HPV vaccine uptake during adolescence. Few studies in the United States have examined psychosocial determinants of HPV vaccine acceptability and hesitancy among Black parents. The current study integrated the health belief model and the theory of planned behavior to evaluate the extent to which psychosocial factors are associated with pediatric HPV vaccination intentions among this population. Methods: Black mothers (N = 402; age range = 25 to 69 years, M = 37.45, SD = 7.88) of daughters ages 9 to 15 years completed an online survey assessing HPV infection and vaccine beliefs and attitudes across four domains: Mother's HPV Perceptions, Mother's Vaccine Attitudes, Cues to Action, and Perceived Barriers to HPV Vaccination. Participants indicated their willingness to vaccinate their daughter on a 5-level ordinal scale ("I will definitely not have my daughter get the vaccine" to "I will definitely have my daughter get the vaccine") which was dichotomously recoded for binomial logistic regressions. Results: Half of the sample (48%) intended to vaccinate their daughter. Number of daughters, mother's HPV vaccine status, perceived HPV vaccine benefits, HPV vaccine safety concerns, pediatric HPV vaccine peer norms, and doctor recommendations emerged as independent factors of Black mothers' intentions to vaccinate their daughters against HPV when controlling for all other factors. Discussion: In addition to medical training to increase doctor recommendation of the HPV vaccine for Black girls, population-tailored public health messaging aimed at promoting HPV vaccine acceptance among Black mothers is urgently needed. This messaging should engage community support and emphasize the benefits of vaccination for adolescent Black girls while also addressing parental concerns regarding the safety of pediatric HPV vaccination.

Afraid but misinformed: Conspiracist beliefs cancel the positive influence of fear of COVID-19 on vaccination intentions - Findings from a Romanian sample.

Understanding the factors that make people more likely to refuse vaccination against COVID-19 is crucial in order to design public health messages efficient in increasing vaccination rates. As COVID-19 creates risks of seriously damaging health effects, fear of this disease is as a significant determinant of vaccination intentions, as indicated by past research. Nevertheless, this positive influence may be limited in people who do not consider vaccines as a solution to protect against COVID-19, especially those who hold conspiracist beliefs about the new coronavirus and, implicitly, about the newly developed vaccines. The present study examined in a cross-sectional design on a convenience sample (N = 564) the joint effect of fear of COVID-19 and conspiracist beliefs on vaccination intentions, advancing past research on their independent influences. Furthermore, we investigated and controlled the effects of perceived risk of catching COVID-19, trust in medical experts, attitude towards vaccination and socio-demographical characteristics (i.e., gender, age, and education), previously found to be associated to COVID-19 vaccination intentions. We also tested the effect of ambivalence towards vaccination, i.e., the degree to which people simultaneously hold positive and negative evaluations of this intervention, as the widespread misinformation on the new coronavirus and its vaccines may induce ambivalence on this latter issue in many people. The results showed that the positive effect of fear of COVID-19 on vaccination intentions emerged only in participants who tend not to endorse conspiracist ideas on the new coronavirus. Moreover, higher vaccine hesitancy was found in participants with higher ambivalence towards vaccination, in those who perceive the risk of being contaminated by the new coronavirus as low, and in those with more negative attitudes towards vaccines in general. Vaccine ambivalence also emerged as a mediator of the negative effects of conspiracist beliefs about COVID-19 on vaccination intentions. This pattern of findings suggests the public messages emphasizing the risks of COVID-19 should also combat misinformation in order to maximize vaccine uptake.

Characteristics of Older People's Belief in Real and Fake News

Introduction. The spread of fake news on the internet is an increasingly serious problem. When analysing belief in fake news, people are usually treated as homogeneous group, however, previous studies suggest that different groups may exist. This study aims to identify clusters of older people according to their level of belief in real and fake news. Methods. 504 people aged 50 to 90 years (M=64.37, SD=9.10) participated in the study. Belief in true and false news was assessed using 10 news headlines (six false, four true). Respondents' vaccination intentions and trust in democratic institutions were assessed. A cluster analysis was performed to distinguish between groups of respondents. Results. Four clusters were identified and replicated: moderately believing in fake and real news;believing in real but not in fake news;tending not to believe in either real or fake news;and tending to believe in both real and fake news. Individuals who fell into the cluster of believers in both real and fake news had lower intentions to vaccinate against COVID-19 and lower trust in political institutions. Conclusions. The study provides evidence that people aren't homogeneous in their belief in fake and real news, and four meaningful clusters can be distinguished. © 2023 Antanas Kairys, Vytautas Jurkuvėnas, Vita Mikuličiūtė, Viktorija Ivleva, Vilmantė Pakalniškienė.

Psychosocial Predictors of Intention to Vaccinate Against the Coronavirus (COVID-19).

The COVID-19 pandemic has wreaked havoc across the world. Public health efforts to combat the disease and return life to normalcy largely rests upon COVID-19 vaccination distribution and uptake. Thus, it is critical to examine factors that predict people's intentions to vaccinate. This study explored predictors of intention to vaccinate against COVID-19 among demographic and personal factors, health behaviors and beliefs, COVID-19-specific beliefs, and trust in physicians, using a sample of U.S. adults. We employed bivariate correlations and hierarchical regression to analyze the data. We found that the strongest predictors are political orientation, trust in physicians, subjective norms, and prior flu shot uptake. These associations suggest that individuals who held more liberal political views, expressed higher levels of trust in their primary care provider, perceived stronger social pressure to vaccinate against COVID-19, and received a flu shot during the previous flu season, had a stronger intention to vaccinate against COVID-19. Based on our results, we suggest that public health efforts to increase vaccination uptake for COVID-19 vaccines focus on addressing political orientation (conservatism), involve primary care providers, emphasize vaccination as the norm (and not the exception), and use information about previous flu vaccinations to target vaccination campaigns.

Cultural, societal, and personal factors impacting COVID-19 vaccine intentions among American Indians and Alaska natives

SARS-CoV-2, better known as COVID-19, has impacted all people globally. In the United States, the impact of COVID-19 has been extremely devastating for American Indian and Alaska Native populations. Historically, this resilient population has been battling numerous epidemics since first contact with European colonizers. These epidemics, coupled with COVID-19, have led to a deadly syndemic for American Indians and Alaska Natives. Understanding what cultural, societal and individual factors are involved in health decisions can help mitigate the impact of COVID-19 and better inform policies. This dissertation used a mixed-method approach to examine 1) what cultural, societal, and individual factors can predict COVID-19 vaccine intent (Chapter 2 & 3) and 2) to understand the phenomenology of tribal COVID-19 policies and tribal governmental actions implemented in response to the pandemic (Chapter 4). Results demonstrate that ethnic identity, age, education, smoking status, type of employment, handwashing behaviors and a belief that traditions can prevent COVID-19 infection were all predictive of COVID-19 vaccine intent. Furthermore, results show that tribes relied heavily on federal recommendations and traditional values when implementing strategies to keep their communities safe. Tribes with limited infrastructure had a more challenging time disseminating policy to their members, but others found that social media was an effective medium for policy dissemination.

Fearing the disease or the vaccine: The case of COVID-19.

As studies indicate that people perceive COVID-19 as a threatening disease, the demand for a vaccine against the disease could be expected to be high. Vaccine safety concerns might nevertheless outweigh the perceived disease risks when an individual decides whether or not to accept the vaccine. We investigated the role of perceived risk of COVID-19 (i.e., perceived likelihood of infection, perceived disease severity, and disease-related worry) and perceived safety of a prospective vaccine against COVID-19 in predicting intentions to accept a COVID-19 vaccine. Three Finnish samples were surveyed: 825 parents of small children, 205 individuals living in an area with suboptimal vaccination coverage, and 1325 Facebook users nationwide. As points of reference, we compared the perceptions of COVID-19 to those of influenza and measles. COVID-19 was perceived as a threatening disease-more so than influenza and measles. The strongest predictor of COVID-19 vaccination intentions was trusting the safety of the potential vaccine. Those perceiving COVID-19 as a severe disease were also slightly more intent on taking a COVID-19 vaccine. Informing the public about the safety of a forthcoming COVID-19 vaccine should be the focus for health authorities aiming to achieve a high vaccine uptake.

The differential effects of a governmental debunking campaign concerning COVID-19 vaccination misinformation.

BACKGROUND: Throughout the ongoing COVID-19 pandemic debunking misinformation has been one of the most employed strategies used to address vaccine hesitancy. We investigated whether - and for whom - debunking is effective or even counterproductive in decreasing misinformation belief and vaccination hesitancy. METHOD: We conducted a randomized controlled trial (N = 588) utilizing a real-world debunking campaign from the German Ministry of Health. We considered the condition (debunking vs. control) as between-subjects factor, assessed misinformation belief (pretest vs. posttest) as a repeated-measures factor and vaccination intention as a dependent variable. Preregistered subgroup analyses were conducted for different levels of a priori misinformation belief and general vaccination confidence. RESULTS: The analyses revealed differential effects on misinformation belief and vaccination intention in participants with low, medium, and high a priori belief: A debunking effect on misinformation belief (dRM = -0.80) was only found in participants with a medium a priori belief and did not extend to these participants' vaccination intentions. Among participants with a high a priori misinformation belief, explorative analysis revealed a small unintended backfiring effect on vaccination intentions (ηp2 = 0.03). CONCLUSIONS: Our findings suggest that debunking is an effective communication strategy to address moderate levels of misinformation beliefs, but it does not constitute a one-fits-all strategy to reduce vaccination hesitancy among the general public. Although countering misinformation should certainly be an integral part of public health communication, additional initiatives, which address individual concerns with targeted and authentic communication, should be taken to enhance the impact on hesitant populations and avoid backfiring effects.

COVID-19 Vaccination Attitudes and Intentions Among U.S. Soldiers: Results from the U.S. Army Behavioral Health Advisory Team (BHAT).

INTRODUCTION: The objective of this study is to characterize the associations between demographic, attitudinal, and leadership factors with COVID-19 vaccination rates, vaccination intentions among those not vaccinated, and attitudes about vaccination safety, effectiveness, and importance. METHODS: A serial cross-sectional anonymous online survey was administered to soldiers at two large U.S. Army Divisions located in the Southwestern region of the U.S. at two different time points (April-May 2021 [Time 1; T1] N = 24,629; July-August 2021 [Time 2; T2] N = 21,116). Binary logistic regressions were used to assess demographic and attitudinal predictors of vaccination receipt and vaccination intent. Multinomial logistic regressions were used to assess demographic and leadership predictors of endorsement of three vaccination attitudes concerning effectiveness, safety, and importance. RESULTS: Approximately 43% of soldiers reported that they received a COVID-19 vaccine at T1, increasing to 67% at T2. Soldiers who agreed with three separate statements on vaccination effectiveness, safety, or importance were more likely to indicate that they intended to get the vaccination at both time points. Soldiers who reported that their immediate supervisor encouraged soldiers to get a COVID-19 vaccine were more likely to indicate that the vaccination was effective, safe, or important at both time points. DISCUSSION: Negative attitudes about COVID-19 vaccines were prevalent and correlated with less intention to get a vaccination. However, prioritizing leadership engagement around the importance of vaccinations may be a simple but widely effective intervention point to increase future vaccine uptake following the development of novel vaccines to future COVID-19 variants.

The impact of COVID-19-related information scanning via social media on Chinese intentions regarding coronavirus vaccinations

Background: During the COVID-19 health crisis, there is a recognized need for addressing vaccine hesitancy to increase vaccination rates globally. In this context, exploring the underlying public behavioral mechanism related to COVID-19 vaccine decisions has been the focus of much investigation. Objective: This thesis seeks to investigate and explain the impact of COVID-19-related information scanning via social media on health perceptions and behavioral intentions to receive COVID-19 vaccine doses in China. Methods: By distributing a questionnaire online, 483 respondents were recruited. Then, the present study applied partial least squares structural equation modeling (PLS-SEM) by using Smart PLS 3.3. Finally, the variance of path relationships among different socio-demographic groups was tested by performing multigroup analysis. Results: COVID-19 information scanning via social media has positive influence on four constructs, including perceived severity (β = 0.355, p < 0.01), perceived vulnerability (β = 0.140, p < 0.05), self-efficacy (β = 0.360, p < 0.01) and response efficacy (β = 0.355, p < 0.01). No significant correlation was found between threat appraisal and behavioral intentions to get vaccinated, including perceived severity and perceived vulnerability. And scanned information exerts influence through other significant factors, including self-efficacy (β = 0.379, p < 0.01), response efficacy (β = 0.275, p < 0.01) and response cost (β = −0.131, p < 0.05). Additionally, response efficacy exerts stronger influences on men's behavioral intentions, whereas response cost and perceived vulnerability are stronger mediators among women. Surprisingly, scanned information is positively associated with response cost among older adults, and perceived vulnerability was negatively associated with behavioral intentions to receive the coronavirus vaccines among younger adults. And there were significant differences in the association of perceived vulnerability and behavioral intentions between lower and higher educated groups. Conclusion: The present results highlight the key roles of COVID-19-related scanned information on public health perceptions and behavioral intentions. Tailored health communication must deliver factual information, address the public uncertainty regarding adverse effect of COVID-19 vaccine, and clarify vaccine schedules.

Vaccination willingness among undergraduates: Role of conspiracy mentality and belief in Covid-19 vaccine conspiracies.

OBJECTIVE: To investigate willingness to vaccination, conspiracy mentality, and belief in vaccine conspiracies among undergraduate students as well as the level of adherence to non-pharmaceutical interventions during the coronavirus disease-2019 pandemic. METHODS: The cross-sectional study was conducted from January to June, 2021, and comprised undergraduate students from Islamabad and Rawalpindi, Pakistan. Data was gathered using the General Conspiracy Mentality Scale and the Belief in Vaccine Conspiracies Scale. Willingness for vaccination and degree of adherence to non-pharmaceutical interventions was measured on a 5-point rating scale. Data was analysed using SPSS 26. RESULTS: Of the 300 subjects, 154 were males and 146 were females. The overall mean age of the sample was (23.47 ±2.17). A sample of 121(40.33%) respondents believed in vaccine conspiracies, while only 83(27.66%) showed disagreement. High scores on conspiracy mentality (p<0.020) and belief in vaccine conspiracies (p<0.006) were associated with little adherence to behavioural recommendations for coronavirus disease-2019. High scorers on conspiracy mentality (p<0.006) and belief in vaccine conspiracies (p<0.004) had less willingness for vaccination. There was no significant difference in the conspiracy mentality and belief in vaccine conspiracies with reference to gender (p>0.05). CONCLUSIONS: Medical practitioners and healthcare organisations need to understand the connection between belief in vaccine conspiracies and related vaccine resistance and noncompliance with behavioural recommendations in the face of a pandemic.

Health Belief Model (HBM) and vaccination during pandemics

Introduction: With the COVID-19 pandemic recognized as a major threat to human health, promoting vaccination is of paramount importance to public health. Objective(s): To examine the association between factors of the Health Belief Model (HBM) and intentions to be vaccinated against COVID-19, when a vaccine becomes available. Method(s): A literature review has been made through PubMed database. Result(s): The HBM dimensions "perceived barriers", "perceived benefits" and "perceived severity" were considered to be significant predictors of acceptance of vaccinations. The HBM constructs of cues to action (trust in third-party information sources), perceived severity of and susceptibility to COVID-19, and beliefs about the protection benefits of a COVID-19 vaccine, subsequently may elicit willingness to vaccinate. Individual predictors of vaccination were believing the vaccine is effective at preventing COVID-19, recalling their doctor recommending the vaccine. Common perceived barriers against vaccination included believing the vaccine could give people the virus, believing the vaccine can make individuals ill afterwards and preferring to develop immunity "naturally". Patients who delayed and refused vaccine doses were more likely to have vaccine safety concerns and perceive fewer benefits associated with vaccines. Conclusion(s): HBM is an effective tool for identifying facilitators and barriers to health behaviors. Health promotion should make use of the HBM, as the model provides a theoretically understanding of the dynamics that may enable the success of important health-related policy in the wake of COVID-19 and future pandemics and identifies the communication mechanisms that must be leveraged by governments and authorities in enforcing policy.

Distrustful Complacency and the COVID-19 Vaccine: How Concern and Political Trust Interact to Affect Vaccine Hesitancy.

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency-an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%-22% more vaccine hesitant than respondents with either high trust or high concern, and 26%-29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations.

How Does Migration Background Affect COVID-19 Vaccination Intentions? A Complex Relationship Between General Attitudes, Religiosity, Acculturation and Fears of Infection.

Objectives: The aim of the study is to investigate the relationship between migration background and COVID-19 vaccine intentions, exploring multiple mediation paths. We argue that the migrational and sociocultural background influences general attitudes toward health and political/public institutions. The effects of these general attitudes on vaccination intentions are mediated by fears of infection. Additionally, we analyze a migrant-only model including acculturation variables (years since migration, foreign and host country media consumption) and region of origin (European vs. Non-European). Design: The data (n = 1027) stem from an online access panel collected between March 15 and March 25, 2021. Quotas for gender and age were set according the online population of Germany. The use of an oversampling framework for first generation migrants resulted in a sample with 50% first generation migrants and 50% native Germans without migration background. Models were calculated using a Structural Equation Modeling approach. Results: Migration background both increases and decreases antecedents of vaccination intentions. Being a migrant increases positive antecedents like religiosity, which in turn positively influence general attitudes and thus fears of infection and vaccination intentions. But being a migrant has also a significant direct negative association with vaccination intentions, implying missing mediators. Increasing years since migration increase host country (German) media consumption and decrease consumption of media from the country of origin. Both media variables are positively associated with political trust and health consciousness. Additionally, European compared to Non-European migrants have less political trust, fear of personal infection and lower vaccination intentions on the whole. Conclusions: The study found that vaccination intentions can be understood by applying the proposed hypothetical structure. We found complex associations of the migration and sociocultural background and COVID-19 vaccination intentions, where antecedents of vaccination intentions are both increased and decreased by migration background and migration specific factors.

Correlates of COVID-19 vaccination intentions: Attitudes, institutional trust, fear, conspiracy beliefs, and vaccine skepticism.

Successful campaigns to combat the COVID-19 pandemic depend, in part, on people's willingness to be vaccinated. It is therefore critical to understand the factors that determine people's vaccination intentions. We applied a reasoned action approach - the theory of planned behavior - to explore these factors. We used data from an online survey of adults (18-74 years; n = 5044) conducted in Germany between April 9 and April 28, 2021 and found that attitudes toward getting vaccinated predicted vaccination intentions, while normative and control beliefs did not. In turn, positive attitudes toward getting vaccinated were supported by trust in science and fear of COVID-19 whereas negative attitudes were associated with acceptance of conspiracy theories and skepticism regarding vaccines in general. We advise policymakers, physicians, and health care providers to address vaccination hesitancy by emphasizing factors that support positive attitudes toward getting vaccinated, such as prevention of serious illness, death, and long-term health detriments, as opposed to exerting social pressure or pointing to the ease of getting vaccinated.

Cognitive underpinnings of COVID-19 vaccine hesitancy.

RATIONALE: Vaccines save lives. Despite the undisputed value of vaccination, vaccine hesitancy continues to be a major global challenge, particularly throughout the COVID-19 global pandemic. Since vaccination decisions are counter-intuitive and cognitively demanding, we propose that vaccine hesitancy is associated with executive function-a group of high-level cognitive skills including attentional control, working memory, inhibition, self-regulation, cognitive flexibility, and strategic planning. OBJECTIVE: We set out to test (i) whether vaccine hesitancy is driven by individual differences in executive function beyond established socio-demographic factors (e.g., education, political orientation, gender, ethnicity, age, religiosity) and depressed mood, and (ii) whether this relationship is exacerbated by situational stress. METHODS: Two studies were conducted with U.S. residents. Using a cross-sectional design, Study 1 examined the associations between executive function, socio-demographic factors, COVID-19 conspiracy beliefs, trust in health authorities, and COVID-19 vaccine hesitancy. Using an experimental design, Study 2 focused solely on unvaccinated individuals and tested the interactive effect of executive function and stress on willingness to receive a COVID-19 vaccine. We used ordinal logistic regressions to analyze the data. RESULTS: Individual differences in executive function predicted participants' COVID-19 conspiracy beliefs, trust in health authorities, and their willingness to vaccinate against COVID-19. Importantly, the unique contribution of executive function to vaccine hesitancy could not be explained by socio-demographic factors or depressed mood. Furthermore, Study 2 revealed that weaker executive function had detrimental effects on COVID-19 vaccine acceptance and trust in health authorities mainly under heightened stress. CONCLUSIONS: Individual differences in executive function and situational stress jointly impact COVID-19 vaccination decisions and need to be considered together when designing health communications aimed at reducing COVID-19 vaccine hesitancy. Interventions that lower stress and promote trust have the potential to increase vaccine acceptance, especially for individuals with weaker executive function.

Barriers and facilitators of willingness to vaccinate against COVID-19: Role of prosociality, authoritarianism and conspiracy mentality. A four-wave longitudinal study.

AIM: We investigated longitudinal relations between individual willingness to undergo vaccination against COVID-19 and three social factors: conspiracy mentality, prosociality, and authoritarianism. METHOD: This longitudinal study comprised four measurement points. The first wave sample included 1130 responses and was representative of the Polish population in terms of gender, age, and place of residence. Analyses were performed using random intercept cross-lagged panel models. RESULTS: We observed bidirectional positive cross-lagged relationships between prosociality and willingness to undergo vaccination in the first three waves of measurement. Authoritarianism and conspiracy mentality translated into a lower willingness to vaccinate between the third and fourth points of measurement when the vaccination became a near-term possibility. CONCLUSIONS: Eliciting prosocial motivation to vaccinate can be paramount in overcoming vaccine hesitancy. Because conspiracy thinking may be a crucial barrier to willingness to be vaccinated, it is critical to focus on planning interventions and campaigns undermining conspiracy theories about COVID-19.

Scarcity in COVID-19 vaccine supplies reduces perceived vaccination priority and increases vaccine hesitancy

In two experimental studies, we tested the effect of COVID-19 vaccine scarcity on vaccine hesitancy. Based on extensive scarcity literature, we initially predicted that high (vs. low) scarcity would increase demand for vaccines, operationalized as one's willingness to receive a vaccine. Contrary to this prediction, Study 1 showed that scarcity of vaccines reduced participants' sense of priority which, in turn, also reduced their vaccination intentions. Trust in doctors moderated the effect of perceived vaccination priority on vaccination intentions such that for individuals with high trust in doctors, reduced perceived priority did not reduce their vaccination intentions as much. Study 2 replicated these effects with a more general population sample, which included at-risk individuals for COVID-19 complications. At-risk participants (vs. low-risk) had higher perceived vaccination priority, but describing vaccine doses as scarce reduced vaccination intentions similarly across both groups. Moreover, Study 2 demonstrated that compassion for others is a boundary condition of the effect of vaccine scarcity on vaccination intentions. For participants with high compassion, scarcity reduces willingness to receive a vaccine;for participants with low compassion, scarcity increases their willingness to be vaccinated. Our results suggest that health policymakers need to deemphasize the scarcity of vaccines to increase vaccine acceptance.

The seductive allure of technical language and its effect on covid-19 vaccine beliefs and intentions.

Previous research has demonstrated a 'seductive allure' of technical or reductive language such that bad (e.g., circular) explanations are judged better when irrelevant technical terms are included. We aimed to explore if such an effect was observable in relation to a covid-19 vaccinations and if this subsequently affected behavioural intentions to take up a covid-19 vaccine. Using a between subjects design we presented participants (N = 996) with one of four possible types of vignette that explained how covid-19 vaccination and herd immunity works. The explanations varied along two factors: (1) Quality, explanations were either good or bad (i.e., tautological); (2) Language, explanations either contained unnecessary technical language or did not. We measured participants' evaluation of the explanations and intentions to vaccinate. We demonstrate a 'seductive allure' effect of technical language on bad vaccine explanations. However, an opposite 'repellent disdain' effect occurred for good explanations which were rated worse when they contained technical language. Moreover, we show that evaluations of explanations influence intentions to vaccinate. We suggest that misinformation that includes technical language could be more detrimental to vaccination rates. Importantly, however, clear explanatory public health information that omits technical language will be more effective in increasing intentions to vaccinate.

Body Appreciation as a Factor Associated with College Students' Willingness to Receive Future COVID-19 Vaccines.

BACKGROUND: Following the initial manufacture of COVID-19 vaccines, numerous studies have investigated factors that influence people's vaccination intentions. However, no studies have examined links of vaccination attitudes with body-related attitudes, especially body appreciation. To address this gap in the literature, we conducted this study to disentangle the relationship between college students' COVID-19 vaccination intentions and body appreciation. METHOD: A cross-sectional study was conducted among Chinese college students. Participants completed the Body Appreciation Scale-2 (BAS-2) and other questionnaire measures of demographics, intentions to be vaccinated, and attitudes toward COVID-19 vaccination programs. RESULTS: A total of 2058 college students participated in this study. Students who were willing to get COVID-19 vaccines had significantly higher BAS-2 scores than did those who were unwilling to receive a vaccine (3.61 ± 0.84 vs. 3.34 ± 0.92, p < 0.001). A hierarchical multiple logistic regression analysis was performed to test the association between body appreciation and COVID-19 vaccine intentions when controlling for other covariates; elevated BAS-2 scores were associated with greater willingness to receive COVID-19 vaccines (OR = 1.250, 95%CI: 1.112-1.406, p < 0.001), independent of other significant influences. CONCLUSION: Our study was the first to reveal that body appreciation is a significant factor related to college students' COVID-19 vaccination intentions. Public health interventions designed to improve people's body-appreciation levels may help in efforts to promote universal immunization.
