The effect of trust and proximity on vaccine propensity

Ideological differences in COVID-19 vaccine intention: the effects of trust in the healthcare system, in complementary and alternative medicine, and perceived threat from the disease

Introduction

Politically left-leaning individuals are more likely to get vaccinated against COVID-19, although little is known about the mechanisms underlying the ideological differences in vaccination intentions. Understanding the extent to which trust in the healthcare system, in complementary and alternative medicine, and the perceived threat from the disease contribute to these disparities is crucial, as it could inform targeted interventions to address vaccine hesitancy across the political spectrum.

Methods

The present cross-sectional study conducted among adults living in Slovenia (n = 858) examined the mediating role of trust in the healthcare system, trust in complementary and alternative medicine (CAM), and the perceived threat from the virus on COVID-19 vaccination intention.

Results

We found that leftist ideology and trust in the healthcare system positively predicted vaccination intention, whereas CAM negatively predicted this intention. In addition, left-leaning individuals expressed greater trust in the healthcare system and lower trust in CAM, resulting in higher levels of COVID-19 vaccination intention. The serial mediation model confirmed that trust in CAM was a negative predictor, while trust in the healthcare system positively predicted perceived threat.

Discussion

When dealing with vaccine hesitancy among right-oriented individuals, strategies should focus on enhancing trust in the healthcare system and critically evaluating the reliance on CAM.

Examining American attitudes toward vaccination during the COVID-19 pandemic from the perspective of negative and positive rights

We examine the likely acceptance of the COVID-19 vaccine in the period prior to political polarization around vaccine mandates. Two representative cross-sectional surveys of 1,000 respondents were fielded in August and December 2020. The surveys included items about the COVID-19 vaccine and vaccine mandates. Respondents self-identifying as liberal were the least likely to believe the vaccine had undisclosed harmful effects (p< .001), conservatives were the most likely (p < .001), and moderates fell in between. Individuals with a bachelor's degree were less likely to think the vaccine had undisclosed harmful effects than individuals without a bachelor's degree (p < .001), and 60.5% of those individuals did not support a government vaccine mandate. Political ideology was more often strongly associated with avoiding government involvement compared to education level. In summary, both liberal political ideology and higher education were significantly associated with endorsing intended vaccine uptake. We discuss these results in terms of positive versus negative rights.

What Causes the Discrepancy in SARS-CoV-2 Vaccine Between Parental Hesitancy for Themselves and for Their Children During Lockdown Period?

BACKGROUND

Parents are usually the decision-makers for vaccinations of children. Therefore, it is important to understand parental beliefs and attitudes toward severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine for themselves and their children when it was approved for children age 3-17.

METHOD

A cross-sectional survey based on an anonymous online questionnaire for parents was conducted in seven provinces of China, and demographic information, vaccination history, parental decision motives, and health belief model toward themselves and their children were collected, respectively.

RESULTS

The overall parental hesitancy rate toward themselves was 20.30%, and that toward their children was 7.80%. More parental concerns on disease severity (odd ratio [OR] = 1.11, 95% confidence interval [CI]: 1.01-1.61) and susceptibility (OR = 1.29, 95% CI: 1.01-1.63) of children could be the causes of discrepancy in hesitancy for themselves and for their children. Parents who hesitated to vaccinate themselves might also be hesitated to vaccinate their children (β = 0.077, P < 0.001).

CONCLUSION

Threat perception may lead to inconsistencies in parental vaccination decisions toward themselves and toward their children. Correcting misinformation and strengthening education about COVID-19 are of great significance in addressing vaccine hesitancy among parents and children.

Political Partisanship and Trust in Government Predict Popular Support for COVID-19 Vaccine Mandates for Various Professions and Demographic Groups: A Research Note

Due to the slow rate of COVID-19 vaccine uptake and the spread of the highly contagious Omicron variant, governments are considering mandating COVID-19 vaccination for specific professions and demographic groups. This study evaluates popular attitudes toward such policies. We fielded a survey of 535 registered voters in South Dakota to examine popular attitudes towards vaccine mandates for five groups-children 12 and older, K-12 teachers, medical staff, nursing homes staff, and police personnel. We estimated a series of logistic regression models and presented predicted probabilities to find the primary determinants of these attitudes. Results revealed that political partisanship and trust in government are strong predictors of support for vaccine mandates across all models. Should government and public health officials wish to increase the proportion of people vaccinated for COVID-19, they must recognize the limitations of current public health campaigns, and reshape their efforts in congruence with scientific findings.

Political Partisanship, Trust, and Attitudes toward COVID-19 Vaccines in Indonesia

CONTEXT

This study examines the extent to which political partisanship-measured as support for either the incumbent candidate for Indonesia's presidency, Joko Widodo (popularly known as Jokowi), or for Jokowi's challenger, Prabowo-affects individuals' risk perception of COVID-19 and COVID-19 vaccine hesitancy and refusal as well as beliefs about the safety and efficacy of the COVID-19 vaccine.

METHODS

The authors performed multinomial logistic and ordinary least squares regression analyses on a nationally representative sample of a national survey on public trust in COVID-19 vaccines and vaccinations that was conducted in December 2020.

FINDINGS

Individuals who voted for Prabowo in the 2019 presidential election were more likely to have a lower level of willingness and a higher level of hesitancy to get the COVID-19 vaccine than those who cast their ballot for Jokowi as the Indonesian president.

CONCLUSIONS

Political partisanship does matter in shaping individuals' hesitancy or refusal to receive the COVID-19 vaccine in Indonesia. The effect of partisanship is also significant in shaping individuals' trust in the efficacy and safety of the COVID-19 vaccine, but it is not significantly associated with individuals' risk perceptions.

Associations between Vaccination Behavior and Trust in Information Sources Regarding COVID-19 Vaccines under Emergency Approval in Japan: A Cross-Sectional Study

We examined the association between COVID-19 vaccination behavior and trust in COVID-19-related information sources during the initial period of COVID-19 vaccination in Japan. A cross-sectional survey was conducted in August 2021, 5 months after the start of COVID-19 vaccination for the general public under emergency approval. Participants were recruited using non-probability quota sampling from among Japanese residents who were under a declared state of emergency. Sociodemographic data, vaccination behavior, and levels of trust in eight media sources of information and three interpersonal information sources were assessed using an online survey form. A total of 784 participants completed the survey. The results of multiple logistic regression analysis showed that age, household income, underlying medical conditions, and living with family were significantly associated with COVID-19 vaccination behavior. Regarding COVID-19 vaccine information sources, trust in public health experts as a source of media information and primary care physicians as a source of interpersonal information showed significantly positive associations with COVID-19 vaccination behavior (odds ratio [OR] = 1.157, 95% confidence interval [CI] 1.017-1.31; OR = 1.076; 95% CI 1.006-1.150, respectively). Increasing trust in public health experts and primary care physicians and disseminating vaccine information from these sources will help promote vaccination under emergency approval.

Decision-making on COVID-19 vaccination: A qualitative study among health care and social workers caring for vulnerable individuals

In January 2021, the Swiss government introduced the first COVID-19 vaccines and prioritized allocation to at-risk individuals and professionals working with them. Despite this opportunity, vaccine uptake among staff employed in retirement homes and institutes for people with disabilities was suboptimal. This study aimed to capture real-time decision-making about COVID-19 vaccine among staff employed in nursing homes and institutes for people with disabilities in Southern Switzerland. We conducted semi-structured phone-interviews with 25 staff employed in retirement homes and institutes for people with disabilities between February and May 2021, i.e., when participants had to decide whether they wanted to adhere to the priority vaccination programme. Among participants, 21 either signed up for the COVID-19 vaccination or were fully or partly vaccinated at the time of the interview. For most participants, the vaccination choice was a challenging process: information appeared to be lacking and conflicting; numerous moral principles were at stake and contradictory; the way vaccination was organized clashed with the health values to which respondents had been previously exposed; finally, the fear of discrimination for those who decided not to get vaccinated loomed over the vaccination choice. Participants decided for or against vaccination based on principles, traditions, emotions, and a reflexive assessment of the personal vs. collective benefit of the vaccination, the latter being the most common within the investigated sample. This study shows that deciding to get vaccinated against COVID-19 is a nuanced process and that individuals cannot simply be categorized as "novax" or "provax" based on their vaccination decision.

Adolescent girls' recommendations for the design of a human papillomavirus vaccination program in Sindh, Pakistan: a qualitative study

PURPOSE

Vaccination of adolescent girls against human papillomavirus (HPV) significantly reduces the incidence of cervical cancer. HPV vaccines are available in Pakistan but plans to develop HPV vaccination program are at a nascent stage. We conducted a formative study to explore adolescent girls' knowledge and perspectives on HPV and cervical cancer and collect their recommendations for implementing an HPV vaccination program in their community.

METHODS

Using qualitative exploratory study design, we conducted four focus group discussions (FGDs) with 12 adolescent girls per group in District West, Karachi. We recruited unmarried girls aged 16-19 years from schools and community settings between May-December 2020. Data analysis was done using NVivo.

RESULTS

Overall, participants displayed a positive attitude toward HPV vaccine. However, they were unfamiliar with basic concepts related to female reproductive health. Female relatives were indicated as girls' preferred point of contact for discussions on HPV and cervical cancer, but fathers were portrayed as decision-making authority on vaccination. Participants indicated vaccine hesitancy among parents may affect HPV vaccination uptake. Girls suggested individual household visits and community-based camps as strategies for successful implementation of HPV vaccination program. A solid foundation of trust between girls' families, program managers, and other stakeholders emerged as a key asset for the program's success.

CONCLUSION

Adolescent girls' suggestions of informing key decision-makers in the family (particularly fathers) of the benefits of HPV vaccination, establishing trust with vaccine providers, and increasing accessibility of vaccinations should be explored for successful implementation of an HPV vaccination program in Pakistan.

Trust in the public health system as a source of information on vaccination matters most when environments are supportive

OBJECTIVES

To understand whether health insurance coverage of vaccine costs and discussing vaccination with a healthcare provider are necessary for trust in CDC (Centers for Disease Control) to increase the uptake of the vaccine.

METHOD

A nationally representative sample of 2,549 adults from the United States answered questions about trust in CDC, insurance coverage, interactions with healthcare providers, and risk perceptions, and then provided longitudinal reports of actual vaccination against influenza during the course of the 2018-19 flu season.

RESULTS

Trust in CDC as a source of information on vaccines was a strong precursor of vaccination. According to multilevel regressions, however, this effect was localized to respondents who had insurance coverage or whose providers discussed the vaccine with them. Further, the effect of trust was even stronger when both insurance coverage and healthcare provider discussions were present.

CONCLUSIONS

Environmental factors supportive of vaccination increased the positive influence of trust in CDC on vaccine uptake by almost 50 percent. Insurance companies and healthcare providers can promote vaccination by covering the costs of vaccination and discussing vaccines in personalized conversations with patients.

COVID-19 Vaccine Uptake in the Context of the First Delta Outbreak in China During the Early Summer of 2021: The Role of Geographical Distance and Vaccine Talk

Purpose

Vaccination is essential to control the prevalence of COVID-19. However, vaccine hesitancy has been a major issue globally. Some studies have suggested that community outbreaks might boost vaccine uptake. Consistent with that idea, vaccination rates increased dramatically during the first outbreak of the COVID-19 Delta variant in Guangdong, China, in June 2021. Based on the risk perception attitude theory, this study attempted to explore the joint effect of geographical distance to the outbreak and the frequency of talking about the COVID-19 vaccine (vaccine talk) on people’s COVID-19 vaccine uptake.

Methods

An anonymous self-report online questionnaire was completed by citizens living in Guangdong Province, China, from June 6 to 11, 2021, during the Delta variant outbreak in that region. The relationship between COVID-19 vaccine uptake, geographical distance to the epicenter of the outbreak, and vaccine talk was analyzed using logistic regression analysis.

Results

Data from 350 respondents were included in the final analysis. Results showed a negative association between geographical distance and COVID-19 vaccine uptake. Furthermore, the relationship was moderated by vaccine talk. Specifically, when individuals infrequently discussed vaccine talk with others, close distance to the epicenter of the outbreak served as a motivator for getting vaccinated, whereas for people who frequently discussed the vaccine, geographical distance might have played less of a role in motivating them to get vaccinated.

Conclusion

This research highlights the joint effect of geographical distance to the outbreak of COVID-19 and vaccine talk in COVID-19 vaccine uptake. While the findings may only be a starting point for launching a public health awareness campaign, encouraging people to engage in more conversations about vaccines may be a promising solution for future health emergencies, especially among people far from the outbreak.

Trust in physicians and trust in government predict COVID-19 vaccine uptake

OBJECTIVE

We consider how trust in government, trust in physicians, and interpersonal trust affect the likelihood of COVID-19 vaccine uptake.

METHODS

A survey of 3057 registered South Dakota voters was fielded in April 2021 that measured COVID-19 vaccine uptake, three aspects of trust, and several other factors related to vaccine hesitancy. Logistic regression was utilized to analyze the responses.

RESULTS

We found positive, statistically significant, and substantively impactful effects for trust in government and trust in physicians on the likelihood of COVID-19 vaccine uptake, and null results for interpersonal trust.

CONCLUSIONS

Our findings provide a more nuanced understanding of the relationship between trust and COVID-19 vaccine uptake, and suggest that public health official as well as physicians should strive to increase the public's trust in the medical community.

Why Vaccinate Against COVID-19? A Population-Based Survey in Switzerland

Objectives: This study examined factors associated with COVID-19 vaccination intention at the very beginning of the vaccination campaign in a representative sample of the population in southern Switzerland.

Methods: In March 2021, we measured vaccination intention, beliefs, attitudes, and trust in a sample of the Corona Immunitas Ticino study.

Results: Of the 2681 participants, 1933 completed the questionnaire (response rate = 72%; 55% female; meanage = 41, SD = 24, rangeage = 5–91). Overall, 68% reported an intention to get vaccinated. Vaccination intention was higher in social/healthcare workers, and increased with age, trust in public health institutions, and confidence in the vaccine efficacy. Prior infection of a family member, predilection for waiting for more evidence on the safety and efficacy of the vaccine, and for alternative protective means were negatively associated with intention.

Conclusion: In view of needs of COVID-19 vaccine boosters and of suboptimal vaccination coverage, our results have relevant public health implications and suggest that communication about vaccine safety and efficacy, and aims of vaccination programs, should be bi-directional, proportionate, and tailored to the concerns, expectations, and beliefs of different population subgroups.

Political Ideologies, Government Trust, and COVID-19 Vaccine Hesitancy in South Korea: A Cross-Sectional Survey

This study aimed to assess the correlation between political ideologies, government trust, and COVID-19 vaccine hesitancy in South Korea during the COVID-19 pandemic. A cross-sectional survey was conducted among South Korea’s general population and 1000 respondents (aged 18 years and older) were included. We used multivariate logistic regression models to identify the factors associated with vaccine hesitancy. Respondents who self-identified as liberal or held “no political opinion” had higher rates of vaccine hesitancy than conservative respondents. People’s trust in the government’s countermeasures was associated with vaccination. Respondents who had risk perceptions (affective and cognitive) of COVID-19 had lower rates of vaccine hesitancy. Perceptions that the vaccine was not safe and being aged 18–29, 30–39, or 40–49 were associated with a higher probability of vaccine hesitancy. This study found that even if vaccine safety and risk perceptions toward COVID-19 were adjusted, self-rated political ideologies and government trust was associated with COVID-19 vaccine hesitancy. More effort to communicate with those who are *liberal or “no political opinion”, younger, and have lower level of trust in the government are required to dissolve vaccine hesitancy. Further studies should analyze the mechanism of COVID-19 vaccine uptake for effective herd immunity.

A review and agenda for integrated disease models including social and behavioural factors

Social and behavioural factors are critical to the emergence, spread and containment of human disease, and are key determinants of the course, duration and outcomes of disease outbreaks. Recent epidemics of Ebola in West Africa and coronavirus disease 2019 (COVID-19) globally have reinforced the importance of developing infectious disease models that better integrate social and behavioural dynamics and theories. Meanwhile, the growth in capacity, coordination and prioritization of social science research and of risk communication and community engagement (RCCE) practice within the current pandemic response provides an opportunity for collaboration among epidemiological modellers, social scientists and RCCE practitioners towards a mutually beneficial research and practice agenda. Here, we provide a review of the current modelling methodologies and describe the challenges and opportunities for integrating them with social science research and RCCE practice. Finally, we set out an agenda for advancing transdisciplinary collaboration for integrated disease modelling and for more robust policy and practice for reducing disease transmission.

Rapid realist review of the role of community pharmacy in the public health response to COVID-19

INTRODUCTION

Community pharmacists and their teams have remained accessible to the public providing essential services despite immense pressures during the COVID-19 pandemic. They have successfully expanded the influenza vaccination programme and are now supporting the delivery of the COVID-19 vaccination roll-out.

AIM

This rapid realist review aims to understand how community pharmacy can most effectively deliver essential and advanced services, with a focus on vaccination, during the pandemic and in the future.

METHOD

An embryonic programme theory was generated using four diverse and complementary documents along with the expertise of the project team. Academic databases, preprint services and grey literature were searched and screened for documents meeting our inclusion criteria. The data were extracted from 103 documents to develop and refine a programme theory using a realist logic of analysis. Our analysis generated 13 context-mechanism-outcome configurations explaining when, why and how community pharmacy can support public health vaccination campaigns, maintain essential services during pandemics and capitalise on opportunities for expanded, sustainable public health service roles. The views of stakeholders including pharmacy users, pharmacists, pharmacy teams and other healthcare professionals were sought throughout to refine the 13 explanatory configurations.

RESULTS

The 13 context-mechanism-outcome configurations are organised according to decision makers, community pharmacy teams and community pharmacy users as key actors. Review findings include: supporting a clear role for community pharmacies in public health; clarifying pharmacists' legal and professional liabilities; involving pharmacy teams in service specification design; providing suitable guidance, adequate compensation and resources; and leveraging accessible, convenient locations of community pharmacy.

DISCUSSION

Community pharmacy has been able to offer key services during the pandemic. Decision makers must endorse, articulate and support a clear public health role for community pharmacy. We provide key recommendations for decision makers to optimise such a role during these unprecedented times and in the future.

Impact of COVID-19 and intensive care unit capacity on vaccination support: Evidence from a two-leg representative survey in the United Kingdom

Background

Overcoming coronavirus disease (COVID-19) will likely require mass vaccination. With vaccination scepticism rising in many countries, assessing the willingness to vaccinate against COVID-19 is of crucial global health importance.

Objective

The goal of this study was to examine how personal and family COVID-19 risk and ICU (intensive care unit) availability just before the pandemics influence the acceptance of future COVID-19 vaccines.

Methods

A two-leg survey was carried out for comparing vaccination attitudes pre-and post-COVID-19. UK residents were surveyed in October 2019 about their vaccination attitudes, and again in a follow-up survey in April 2020, containing the previous questions and further ones related to COVID-19 exposure and COVID-19 vaccine attitudes. The study combined survey results with local COVID-19 incidence and pre-COVID-19 measures of ICU capacity and occupancy. Regression analysis of the impact of individual and public health factors on attitudes towards COVID-19 vaccination was performed.

Results

The October 2019 survey included a nationally representative sample of 1653 UK residents. All of them were invited for the follow-up survey in April 2020, and 1194 (72%) participated. The April 2020 sample remained nationally representative. Overall, 85% of respondents (and 55% of vaccine sceptics) would be willing to be vaccinated against COVID-19. Higher personal and family risk for COVID-19 was associated with stronger COVID-19 vaccination willingness, whereas low pre-COVID-19 ICU availability was associated with lower trust in medical experts and lower COVID-19 vaccine support. Further, general vaccination support has risen during the COVID-19 pandemic.

Conclusion

Support for COVID-19 vaccination is high amongst all groups, even vaccine sceptics, boding well for future vaccination take-up rates. Vaccination willingness is correlated with health care availability during the COVID-19 crisis, suggesting a powerful synergy between health care system performance during crisis and the general population's trust in the medical profession - as reflected in vaccination support.

The Persistence of Vaccine Hesitancy: COVID-19 Vaccination Intention in New Zealand

Building public trust and willingness to vaccinate against COVID-19 is as important as developing an effective vaccine. However, a significant minority of the public are unwilling or hesitant to take a COVID-19 vaccine, when available. A nationally representative sample survey (N = 1040) was conducted in July 2020 in New Zealand to identify factors associated with COVID-19 vaccine intention. A 14-item general vaccine hesitancy scale was tested and found to be significantly associated with COVID-19 vaccine intention. A communication campaign from trusted scientific experts, with information that addresses prevailing concerns about vaccines, is likely to help increase COVID-19 vaccine uptake.

The digital immunization system of the future: imagining a patient-centric, interoperable immunization information system

To ensure the effectiveness of increasingly complex immunization programs in upper-middle and high-income settings, comprehensive information systems are needed to track immunization uptake at individual and population levels. The maturity of cloud systems and mobile technologies has created new possibilities for immunization information systems. In this paper, we describe a vision for the next generation of digital immunization information systems for upper-middle and high-income settings based on our experience in Canada. These systems center on the premise that the public is engaged and informed about the immunization process beyond their interaction with primary care, and that they will be a contributor and auditor of immunization data. The digital immunization system of the future will facilitate reporting of adverse events following immunization, issue digital immunization receipts, permit identification of areas of need and allow for delivery of interventions targeting these areas. Through features like immunization reminders and targeted immunization promotion campaigns, the system will reduce many of the known barriers that influence immunization rates. In light of the global COVID-19 pandemic, adaptive digital public health information systems will be required to guide the rollout and post-market surveillance of the SARS-CoV-2 vaccine.

Risk of disease and willingness to vaccinate in the United States: A population-based survey

BACKGROUND

Vaccination complacency occurs when perceived risks of vaccine-preventable diseases are sufficiently low so that vaccination is no longer perceived as a necessary precaution. Disease outbreaks can once again increase perceptions of risk, thereby decrease vaccine complacency, and in turn decrease vaccine hesitancy. It is not well understood, however, how change in perceived risk translates into change in vaccine hesitancy. We advance the concept of vaccine propensity, which relates a change in willingness to vaccinate with a change in perceived risk of infection-holding fixed other considerations such as vaccine confidence and convenience.

METHODS AND FINDINGS

We used an original survey instrument that presents 7 vaccine-preventable "new" diseases to gather demographically diverse sample data from the United States in 2018 (N = 2,411). Our survey was conducted online between January 25, 2018, and February 2, 2018, and was structured in 3 parts. First, we collected information concerning the places participants live and visit in a typical week. Second, participants were presented with one of 7 hypothetical disease outbreaks and asked how they would respond. Third, we collected sociodemographic information. The survey was designed to match population parameters in the US on 5 major dimensions: age, sex, income, race, and census region. We also were able to closely match education. The aggregate demographic details for study participants were a mean age of 43.80 years, 47% male and 53% female, 38.5% with a college degree, and 24% nonwhite. We found an overall change of at least 30% in proportion willing to vaccinate as risk of infection increases. When considering morbidity information, the proportion willing to vaccinate went from 0.476 (0.449-0.503) at 0 local cases of disease to 0.871 (0.852-0.888) at 100 local cases (upper and lower 95% confidence intervals). When considering mortality information, the proportion went from 0.526 (0.494-0.557) at 0 local cases of disease to 0.916 (0.897-0.931) at 100 local cases. In addition, we ffound that the risk of mortality invokes a larger proportion willing to vaccinate than mere morbidity (P = 0.0002), that older populations are more willing than younger (P<0.0001), that the highest income bracket (>$90,000) is more willing than all others (P = 0.0001), that men are more willing than women (P = 0.0011), and that the proportion willing to vaccinate is related to both ideology and the level of risk (P = 0.004). Limitations of this study include that it does not consider how other factors (such as social influence) interact with local case counts in people's vaccine decision-making, it cannot determine whether different degrees of severity in morbidity or mortality failed to be statistically significant because of survey design or because participants use heuristically driven decision-making that glosses over degrees, and the study does not capture the part of the US that is not online.

CONCLUSIONS

In this study, we found that different degrees of risk (in terms of local cases of disease) correspond with different proportions of populations willing to vaccinate. We also identified several sociodemographic aspects of vaccine propensity. Understanding how vaccine propensity is affected by sociodemographic factors is invaluable for predicting where outbreaks are more likely to occur and their expected size, even with the resulting cascade of changing vaccination rates and the respective feedback on potential outbreaks.

Beliefs towards vaccination and trust in the scientific community in Italy

BACKGROUND

In 2017 the Italian government introduced compulsory vaccination for Italian school children for ten diseases, in response to an alarmingly decrease in coverage and measles outbreak. A hot social debate arose around the issue of the law. Studies on the opinion of Italians on this topic are rare, so we investigated the socio-cultural profile of Italians about beliefs towards vaccination.

METHODS

Data were extracted from the Italian section of the European Social Survey (ESS), conducted by the Italian National Institute for Public Policies Analysis during 2017. The main outcome assessed was the opinion about the supposed harmfulness of vaccines. We analysed the association between the outcome and a selected group of socio-cultural characteristics, with a specific interest in examining the interaction between our main outcome and the perceived trust in the scientific community in regards to vaccines. A principal component analysis was then performed for determining the socio-cultural profile of respondents.

RESULTS

Among the 2,626 subjects interviewed face to face, 19% believed that vaccines were harmful and 10% did not have trust in the scientific community in regards to vaccines. Out of the respondents who believed in the harmfulness of vaccines, 29% neither had trust in the scientific community. Principal Component Analysis suggested that this group (Anti-vax/science sceptic) was characterised by low participation in political and cultural life, being male, older of age and politically oriented towards the right. People agreeing about harmfulness of vaccines are mostly males, have a lower education level, poor attendance in political and cultural life and are politically oriented to the right.

CONCLUSIONS

The ESS survey is unique in its capacity to deal with emerging themes of the social debates. Results paint a picture of the opinions of Italians on vaccines. This profile may be useful for policymakers to design targeted vaccination campaigns and to intervene more efficaciously in the public debate.

Parents' malevolent personification of mass vaccination solidifies vaccine hesitancy

Parental hesitancy to vaccinate their children derails the success of mass vaccination campaigns. We examined the effect of parents' personification of the vaccinating agency on vaccine hesitancy (i.e. negative or positive mind change) in 555 parents in a mass wild poliovirus vaccination campaign. Parents were assessed before and after the campaign on attitudes toward vaccination and the vaccinating agency ("The Israeli MoH is caring" vs "hysteric"). Positive mind change was predicted by a gender and malevolent personification. A negative mind change was predicted by parental anxiety. We conclude that parental hesitancy is influenced by parents' attachment to the vaccinating agency.
