Cultural traits or social norms? Both responsibilism and norms linked to accepting covid-19 vaccine

We studied the factors that influence attitudes toward the COVID-19 vaccine by testing 1872 people across 29 provinces in China. We investigated an individual trait (responsibilism) and two situational factors (a descriptive norm and an injunctive norm). Responsibilism is a version of collectivism that emphasizes tight social ties and responsibilities in close relationships. Responsibilism and perceptions of strong social norms predicted acceptance of the COVID-19 vaccine. The data also revealed an interplay between responsibilism and social norms. People high in responsibilism accepted the vaccine regardless of social norms. But people low in responsibilism were wary of the vaccine, unless they perceived strong injunctive norms. These findings contribute to the research on psychological factors behind vaccine hesitancy. The findings could help provide a roadmap for public health efforts to encourage vaccines.

Comparison of attitudes toward routine maternal vaccines and COVID-19 vaccines among pregnant patients in an urban safety-net setting.

OBJECTIVE: To explore attitudes toward tetanus-diphtheria-acellular pertussis (Tdap), influenza, and COVID vaccines among English- and Spanish- speaking pregnant individuals in a safety net setting. METHODS: Pregnant people aged 18 years or older were recruited from outpatient clinics between August 2020 and June 2021. Interviews were conducted via phone in English or Spanish, recorded, transcribed, and translated verbatim. Data were qualitatively analyzed using modified grounded theory and content analysis. RESULTS: 42 patients participated (22 English-speaking, 20 Spanish-speaking). Most participants expressed positive attitudes towards both routine prenatal vaccinations and COVID-19 vaccines, endorsing the belief that vaccines promote health and considering vaccines a social norm. Positive attitudes were similar for the three vaccines, and among Spanish- and English-speaking individuals. Participants trusted their healthcare provider's recommendations and felt comfortable receiving booster doses of vaccines they had received successfully in the past. Vaccine concerns differed by each vaccine. Despite limited knowledge, few participants expressed concerns about Tdap vaccines. Concerns around influenza vaccines often stemmed from personal experience and centered around ineffectiveness and increased risk of flu-like illnesses. Participants expressed the most concerns related to COVID vaccinations, including misinformation about serious side effects and distrust around accelerated approval of the vaccines. Many participants wished to know more about the side effects and safety of vaccinating during pregnancy, especially regarding the fetus's health. CONCLUSIONS: Most participants supported routine prenatal vaccinations, including COVID vaccines. Clinicians are trusted information sources and can help reinforce positive attitudes and social norms of receiving vaccinations in pregnancy while addressing vaccine-specific concerns. FUNDING: This work was supported by Suzanne Cutler Vaccination Education & Research Fund at the Boston University Chobanian and Avedisian School of Medicine for funding and support.

The social value of a SARS-CoV-2 vaccine: Willingness to pay estimates from four western countries.

SARS-CoV-2 vaccines give rise to positive externalities on population health, society and the economy in addition to protecting the health of vaccinated individuals. Hence, the social value of such a vaccine exceeds its market value. This paper estimates the willingness to pay (WTP) for a hypothetical SARS-CoV-2 vaccine (or shadow prices), in four countries, namely the United States (US), the United Kingdom, Spain and Italy during the first wave of the pandemic when COVID-19 vaccines were in development but not yet approved. WTP estimates are elicited using a payment card method to avoid "yea saying" biases, and we study the effect of protest responses, sample selection bias, as well as the influence of trust in government and risk exposure when estimating the WTP. Our estimates suggest evidence of an average value of a hypothetical vaccine of 100-200 US dollars once adjusted for purchasing power parity. Estimates are robust to a number of checks.

User agency–based versus machine agency–based misinformation interventions: The effects of commenting and AI fact-checking labeling on attitudes toward the COVID-19 vaccination

This study aimed to examine the effects of commenting on a Facebook misinformation post by comparing a user agency–based intervention and machine agency–based intervention in the form of artificial intelligence (AI) fact-checking labeling on attitudes toward the COVID-19 vaccination. We found that both interventions were effective at promoting positive attitudes toward vaccination compared to the misinformation-only condition. However, the intervention effects manifested differently depending on participants' residential locations, such that the commenting intervention emerged as a promising tool for suburban participants. The effectiveness of the AI fact-checking labeling intervention was pronounced for urban populations. Neither of the fact-checking interventions showed salient effects with the rural population. These findings suggest that although user agency- and machine agency–based interventions might have potential against misinformation, these interventions should be developed in a more sophisticated way to address the unequal effects among populations in different geographic locations.

The Impact of Socioeconomic Status, Perceived Threat and Healthism on Vaccine Hesitancy

The ideology of healthism and low perceptions of the threat of vaccine-preventable diseases may explain the positive link between socioeconomic status (SES) and vaccine hesitancy in high-income countries. The present study aimed to examine the effect of three measures of SES (education, income and family economic status), the perceived threat of infectious diseases and two dimensions of healthism (personal responsibility for own health and distrust in healthcare institutions) on vaccine hesitancy, adjusting for sociodemographic variables. A cross-sectional quantitative study was performed in 2019. Non-probability sampling was employed by sending invitations to respondents over the age of 18 to participate in the study. The snowball technique was used, employing e-mails and digital social networks (Facebook, Twitter and Instagram). Data from 661 respondents were collected via 1 ka.si, an online survey tool. Multivariate regression analysis indicated that vaccine hesitancy was significantly more likely to be expressed by women (β = 0.09;p < 0.001), high-income respondents (β = 0.09;p < 0.01), those who have lower perceptions of the threat of vaccine-preventable diseases (β = 0.39;p < 0.001) and those scoring high on two healthism measures (expressing high perceived control of their own health (β = 0.18;p < 0.001) and high distrust in the Slovenian healthcare system and institutions (β = 0.37;p < 0.001)). The findings indicate that among the examined predictors, low perceived threat of vaccine-preventable diseases and low trust in the healthcare system are among the strongest predictors of vaccine hesitancy among the Slovenian public. Policymakers, physicians and other healthcare workers should be especially attentive to the public's and patients' perceptions of the risk of infectious diseases and distrust in medical institutions, including during doctor–patient communication and through public health campaigns and policies.

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.

Factors impacting parental uptake of COVID-19 vaccination for U.S. Children ages 5-17.

COVID-19 vaccination of U.S. children lags behind adult vaccination, but remains critical in mitigating the pandemic. Using a subset of a nationally representative survey, this study examined factors contributing to parental uptake of COVID-19 vaccine for children ages 12-17 and 5-11, stratified by parental COVID-19 vaccination status. Among vaccinated parents, uptake was higher for 12-17-year-olds (78.6%) than 5-11-year-olds (50.7%); only two unvaccinated parents vaccinated their children. Child influenza vaccination was predictive of uptake for both age groups, while side effect concerns remained significant only for younger children. Although parents were more likely to involve adolescents in vaccine decision-making than younger children, this was not predictive of vaccine uptake. These results highlight the importance of addressing the unique and shared concerns parents have regarding COVID-19 vaccination for children of varying ages. Future work should further explore adolescent/child perspectives of involvement in COVID-19 vaccination decision-making to support developmentally appropriate involvement.

Institutional trust, scientific literacy, and information sources: What factors determine people's attitudes toward COVID-19 vaccines of different origins in China?

Objective: This study aimed to investigate the different attitudes of Chinese residents toward COVID-19 vaccines produced in China and the United States in an emergency context, and then explored possible explanations for these different attitudes. Methods: Using data collected online in May 2021, we compared Chinese citizens' attitudes toward vaccines originating from China and the US and then adopted ordered logistic models to examine how trust in institutions, scientific literacy, and information sources influence their attitudes toward different vaccines. Results: A total of 2038 respondents completed the survey. Participants reported very different levels of trust in Chinese and American vaccines. The main finding of this paper is that individuals who trust in Chinese institutions, especially those who trust in domestic scientists, typically feel encouraged to also place their trust in domestic vaccines and to distrust those from the US. These individuals' higher evaluation of Chinese government performance makes them more willing to vaccinate with domestic vaccines and less likely to seek US vaccines. Levels of scientific literacy, furthermore, seem to have little influence on attitudes toward different vaccines. Meanwhile, respondents who acquire health information from biomedical journals are more likely to hold a positive view of US vaccines, and these individuals contribute to bridging the gap between levels of trust in Chinese and US vaccines. Conclusions: In contrast with previous findings about Chinese attitudes toward imported vaccines, our respondents are more convinced of the safety and effectiveness of domestic vaccines than of US ones. This trust gap does not arise out of actual disparity in the quality and safety of the different vaccines per se. Instead, it is a cognition concern that is closely bound up with individuals' trust in domestic institutions. People's attitudes toward vaccines of different origins in an emergency context are more influenced by socio-political beliefs than by concern with objective information and knowledge.

COVID-19 vaccine uptake and attitudes towards mandates in a nationally representative U.S. sample.

Widespread uptake of COVID-19 vaccination is vital to curtailing the pandemic, yet rates remain suboptimal in the U.S. Vaccine mandates have previously been successful, but are controversial. An April 2021 survey of a nationally representative sample (N = 1208) examined vaccine uptake, attitudes, and sociodemographic characteristics. Sixty-seven percent were vaccine acceptors, 14% wait-and-see, and 19% non-acceptors. Compared to wait-and-see and non-acceptors, acceptors were more likely to have a household member over age 65, have received a flu shot, have positive COVID-19 vaccine attitudes, and view COVID-19 vaccination as beneficial. Mandate support was higher among respondents who were vaccine acceptors, had positive views about COVID-19 vaccines, believed in COVID-19 preventive strategies, perceived COVID-19 as severe, were liberal, resided in the Northeast, were non-White, and had incomes < $75,000. Public health campaigns should target attitudes that appear to drive hesitancy and prepare for varying mandate support based on demographics, COVID-19 vaccine attitudes, and the scope of the mandate.

The Relationship between Daily Behavior Changes and Vaccine Attitudes at the Early Stage of the COVID-19 Pandemic among Japanese People from Different Demographics: A Retrospective and Exploratory Examination Using a Free-Response Survey.

This study investigated how daily behaviors of Japanese people changed during the early stages of the COVID-19 pandemic and whether the change was mediated by demographics. It also examined whether the magnitude of behavior change in a demographic group is related to their attitudes towards the COVID-19 vaccine. 301 Japanese responded to an online survey in February 2021, in which they first wrote some activities they frequently performed before the virus outbreak and then wrote about activities in their current life. The number of gathered answers were 1858 for 'before' and 1668 for 'after', and they were grouped into 19 behavior categories. Overall, behaviors such as traveling, eating out, and shopping were much less frequently described in the 'after' condition; while housework, food delivery, and pandemic prevention were mentioned more. However, the change pattern was significantly influenced by demographics of age, gender, having children or not, and household income. Especially women, younger generations, and people without children showed the greatest extent of behavior change compared with the other demographic cohorts. These groups were reported to be vaccine-hesitant in the literature. This study suggests that individuals with hesitant attitudes towards vaccines are more willing to change their behaviors to control viral transmission.

Can History of COVID-19 Be Definitive on Coronaphobia and Vaccine Attitudes?

Introduction: To stop the transmission and rapid spread of COVID-19, 60-75% of the population must have immunity. The most appropriate way to ensure this immunity seems to be the widespread use of vaccines. In this study, it was aimed to evaluate the anxiety and control perceptions related to the pandemic in individuals with and without COVID-19 disease. In addition, the relationship between having the disease and vaccine hesitancy was examined. Material(s) and Method(s): Four hundred and thirty-seven participants were included in this study. Participants were evaluated over three groups (Group 1: People who had not contracted COVID-19 before;Group 2: People who had COVID-19 with home treatment without hospitalization;Group 3: People who had contracted COVID-19 and were treated in the hospital). The Perception of Control of COVID-19 Scale (PCo-COVID-19), Attitudes Towards COVID-19 Vaccine Scale, COVID-19 Phobia Scale (CP19-S) were filled in by the participants. Result(s): This study included 290 COVID-19 patients (148 outpatients and 142 inpatients) and 147 participants without COVID-19 disease. Participants with COVID-19 disease had lower PCo-COVID-19 micro control and controllability scores than those without. This finding was interpreted as the individual measures taken to avoid getting the disease seem less sufficient and the controllability of the disease is thought to be lower in those who have had the disease. In addition, positive correlations were found between vaccination attitudes and perception of control subscales (PCo-COVID-19- Macro-control, PCo-COVID-19- Micro-control and PCo-COVID-19-Controllability). Vaccination attitudes were found to be more positive in those with high control perception scale scores. Similar results were obtained in terms of coronaphobia in participants who did not have the disease and those who had the disease at home. However, significantly higher coronaphobia scores (CP19-S) were obtained in inpatients compared to the other two groups. Conclusion(s): Community immunity is important to stop the transmission and rapid spread of COVID-19, which is possible with vaccination. Vaccine hesitancy may hinder successful control of the COVID-19 pandemic. This situation should be considered when preparing health policies. © Copyright 2022 by Flora.

Healthcare workers' attitudes on mandates, incentives, and strategies to improve COVID-19 vaccine uptake: A mixed methods study.

Healthcare workers are a trusted health information source and are uniquely positioned to reduce the burden of the COVID-19 pandemic. The purpose of this sequential exploratory mixed methods study was to understand attitudes of healthcare workers working in Massachusetts during the COVID-19 pandemic regarding strategies to improve COVID-19 vaccine utilization, including vaccine mandates and incentives. Fifty-two individuals completed one-on-one interviews between April 22nd and September 7th, 2021. The survey was developed based on findings from the interviews; 209 individuals completed the online survey between February 17th and March 23rd, 2022. Both the interview and survey asked about attitudes toward COVID-19 vaccine and booster mandates, incentives, and strategies to improve vaccination rates. Most participants were female (79%-interview, 81%-survey), Caucasian (56%, 73%), and worked as physicians (37%, 34%) or nurses (10%, 18%). Overall, nuanced attitudes regarding vaccine and booster mandates were expressed; many supported mandates to protect their patients' health, others emphasized personal autonomy, while some were against mandates if job termination was the consequence of declining vaccines. Similarly, views regarding vaccine incentives differed; some considered incentives helpful, yet many viewed them as coercive. Strategies believed to be most effective to encourage vaccination included improving accessibility to vaccination sites, addressing misinformation, discussing vaccine safety, tailored community outreach via trusted messengers, and one-on-one conversations between patients and healthcare workers. Healthcare workers' experiences with strategies to improve utilization of COVID-19 vaccines and boosters have implications for public health policies. Generally, efforts to improve access and education were viewed more favorably than incentives and mandates.

COVID-19 vaccine controversy: A cross-sectional analysis of factors associated with COVID-19 vaccine acceptance amongst emergency department patients in New York City.

Objective: Understanding variables associated with coronavirus disease 2019 (COVID-19) vaccine confidence and hesitancy may inform strategies to improve vaccine uptake in clinical settings such as the emergency department (ED). We aim to identify factors contributing to COVID-19 vaccine acceptance and to assess patient attitudes surrounding offering COVID-19 vaccines in the ED. Methods: We conducted a survey of a convenience sample of patients and patient visitors over the age 18 years, who were native English or Spanish speakers. The survey was conducted from March through August 2021 at 3 EDs in New York City. The survey was administered via an electronic format, and participants provided verbal consent. Results: Our sample size was 377. Individuals with post-graduate degrees viewed vaccines positively (Prevalence Ratio [PR], 1.63; 95% Confidence Interval [CI], 1.07-2.47).  Of the various high-risk medical conditions associated with adverse COVID-19 infection outcomes, diabetes was the only condition associated with more positive views of vaccines (PR, 1.37; CI, 1.17-1.59). Of all participants, 71.21% stated that they believed offering a COVID-19 vaccine in the ED was a good idea. Of unvaccinated participants, 21.80% stated they would get vaccinated if it were offered to them in the ED. Conclusion: EDs can serve as a safety net for vulnerable populations and can act as an access point for vaccination.

The Impact of Cultural Capital on Vaccine Attitudes among the Slovenian Public.

Education and highbrow cultural participation-two dimensions of cultural capital-have previously been identified as determinants of vaccine attitudes, though the links have been mainly inconsistent across studies. The present quantitative study aimed to examine the effects of two dimensions of cultural capital (institutionalized and embodied cultural capital) on the pro-vaccine attitudes of the Slovenian public. A cross-sectional quantitative study was performed in November 2019, a few months prior to the COVID-19 pandemic. The non-probability sample survey was collected by inviting respondents over the age of 18 to participate using the snowball technique via e-mail, digital social networks (Facebook, Twitter and Instagram) and University of Maribor social network profiles. The sample was obtained through an online survey tool 1ka.si (N = 661; Mage = 34.9 years). The impact of education and highbrow cultural participation on vaccine attitudes was examined, controlling for sociodemographic variables (gender, age and size of residential settlement) and economic variables (income and family economic status) in multivariate analyses. Bivariate analyses indicated that pro-vaccine attitudes were significantly more likely to be expressed by men, younger respondents, those with lower incomes, higher perceived family economic status, living in urban areas and by those who are more frequently engaged in highbrow cultural activities, while education had no impact on vaccine attitudes. The results did not substantially change when multiple regression models were employed. Our study indicated that cultural capital has an inconsistent impact on vaccine attitudes; while education has no impact, highbrow cultural participation increases pro-vaccine attitudes. The results suggest a multi-type approach is needed to address vaccine scepticism among the Slovenian public.

Vaccine confidence among people who use drugs: A cross-sectional survey.

Adult immunization coverage remains low in the US, particularly for people who use drugs (PWUD), a population that experiences a disproportionate burden of vaccine-preventable diseases. The extent of and characteristics associated with vaccine confidence (VC) held by PWUD is poorly understood. As VC strongly correlates with vaccine uptake, this cross-sectional study identifies mutable factors associated with VC and quantifies its relationship to immunization status within a highly vulnerable, underimmunized population of PWUD. Using a community-engaged research strategy with select partner organizations hosting syringe exchange programs in Atlanta, Los Angeles, and Las Vegas, USA, we surveyed participants ages 18-69 years served by these organizations from 2019 to 2020. Survey measures included sociodemographics, health behavior including immunization receipt, and vaccine confidence in adult vaccinations using a modified Emory Vaccine Confidence Index (EVCI). The findings reflect relatively low VC among the 1,127 recruited participants, with 56% expressing low VC (EVCI 0-12), 35% medium (EVCI 13-20) and 10% high (EVCI 21-24). EVCI varied by city, with lowest confidence in Atlanta and highest in Las Vegas. VC was associated with past receipt of specific vaccines, including hepatitis A, MMR, Tdap, and influenza. VC varied by specific sociodemographic correlates such as housing insecurity (reduced confidence) and receipt of public benefits or disability (increased confidence). This study identified correlates associated with VC based on site and sociodemographic characteristics for this priority population, highlighting the need for specific interventions to raise VC among PWUD, especially among those experiencing housing insecurity and without public benefits.

Best shot: A motivational interviewing approach to address vaccine hesitancy in pediatric outpatient settings.

BACKGROUND: Vaccine hesitancy in parents and childhood vaccine refusal is increasing. A standard of care to address this problem has not been identified. PURPOSE: To identify if the use of motivational interviewing by pediatric providers during routine well child visits, when compared to standard of care, would increase vaccine rates in children 0-12 months of age. Factors associated with vaccine hesitancy were also investigated. METHODS: A quasi-experimental study was completed on a convenience sample of pediatric providers (N = 6) and caregivers of children 0-12 months of age (N = 66). Four providers were trained to use motivational interviewing. During the well child visit the Parent Attitudes About Childhood Vaccines survey was completed, and the motivational interviewing intervention was implemented. Clinic's data were compared with other clinic data of non-trained providers. FINDINGS: Vaccine refusal/delays rate was 11.4% among caregivers. Vaccine refusal rate decreased after the intervention (9.00% pre-intervention and 6.40% post-intervention). An ordinal regression identified caregivers with higher vaccine hesitancy scores and more children were more likely to delay or refuse vaccines, while caregivers ≥30 years or with high income were less likely to delay/refuse vaccines. A difference in difference analysis identified that an additional 2.6% of children received vaccines when seen by trained providers compared to non-trained (ß = -0.330, OR = 0.719, p = 0.470). DISCUSSION: Findings indicate a condensed motivational interviewing education session may be clinically significant in decreasing vaccine hesitancy among this population. APPLICATIONS TO PRACTICE: A more robust study to confirm these findings is recommended prior to practice implementation.

Pediatric Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Vaccines: Perceptions and Attitudes From the Food and Drug Administration Public Commentary.

Authorization of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines for children has ushered in a new phase of the immunization campaign to address the pandemic but has been received with mixed responses from parents, children, and opinion leaders. Herein we consider perceptions and attitudes towards pediatric SARS-CoV-2 vaccines from a Food and Drug Administration (FDA) public commentary reflecting more than 63 000 comments.

Did Italy Really Need Compulsory Vaccination against COVID-19 for Healthcare Workers? Results of a Survey in a Centre for Maternal and Child Health.

Since its early spread, the COVID-19 pandemic has become a health threat globally. Due to their crucial role in the pandemic, Italy declared compulsory vaccination for healthcare workers. Vaccine hesitancy was observed among the healthcare workers and an ethical debate arose about Italian legal statement D.L. n. 44/2021. In this article, we present the results of a survey performed in an Italian center for maternal and infant care and assess the attitudes towards the COVID-19 pandemic and the mandatory COVID-19 vaccination of healthcare workers. Since March 2022, 91.5% of healthcare workers have been vaccinated with an additional dose. Only 2.3% of the respondents refused to take vaccination: the reasons behind this refusal were distrust, doubts over safety, and lack of information. Despite the high rate of response to vaccination, 17.7% of HCWs did not agree with its mandatory nature. In addition, 5.4% stated that they agreed to be vaccinated exclusively because of the sanctions provided for by the legislation. In conclusion, adequate vaccination coverage has been achieved in the hospital under consideration. However, it is still very important to continue to persuade HCWs of vaccine efficacy and safety, considering their social role.

The 'Fauci Effect': Reducing COVID-19 misconceptions and vaccine hesitancy using an authentic multimodal intervention.

Social media environments enable users to proliferate misinformation surrounding COVID-19. Expert sources, such as Dr. Anthony Fauci have leveraged social media to present corrective multimedia messages. However, little is known about the efficacy of these messages in revising common misconceptions about COVID-19 and influencing behavior. In this study, we examined the efficacy of a multimodal intervention using authentic social media messages that directly addressed common COVID-19 misconceptions. Going further, we identified individual differences that influenced the effectiveness of the intervention, as well as whether those factors predicted individuals' willingness to receive a COVID-19 vaccine. The results showed that the intervention was successful in increasing knowledge when compared to a baseline control. Those who were older and reported less vaccine hesitancy showed greater learning from the intervention. Factors that significantly predicted intention to vaccinate included receiving the intervention, vaccine confidence, vaccine hesitancy, prior flu vaccination history, age, and fear of COVID-19. These findings indicate that multimodal messages can be effectively leveraged in social media to both fight misinformation and increase intention to be vaccinated - however, these interventions may not be as effective for all individuals.
