The Mediating Roles of Attitude Toward COVID-19 Vaccination, Trust in Science and Trust in Government in the Relationship Between Anti-vaccine Conspiracy Beliefs and Vaccination Intention

Expectations of Katowice residents regarding the program assumptions of the European city of science Katowice 2024 in the field of medical and health sciences - questionnaire survey results

INTRODUCTION

Scientific literacy has been the subject of studies for several decades, but there is much less interest in the social perception of science, traceability of key areas of scientific activity and social expectations regarding science. Proper recognition of such issues can significantly contribute to a better understanding of the causes of the crisis of trust in science and help to find an effective and socially acceptable solution to mitigate it. Our study was aimed at identifying and systematizing the public needs and expectations towards medical and health sciences, based on the example of the population of Katowice.

MATERIALS AND METHODS

The study was carried out using a mixed, qualitative-quantitative methodology. Based on the conclusions of the in-depth interviews, a questionnaire was constructed to check the level of awareness of residents of Katowice obtaining the title of the European City of Science 2024 and the respondents' opinion on the development of medical and health sciences. 400 inhabitants of the city and/or people associated with it through their work or education took part in the questionnaire survey.

RESULTS

Only 7.8% of respondents had in-depth knowledge about the European City of Science 2024 project, with further 28.8% declaring some level of general knowledge of the issue. Study participants associated medical and health sciences with health promotion and clinical specialties (43% and 33,5% respectively). In terms of further development of medical and health sciences in Katowice study participants prioritized mainly development of research in chronic and lifestyle-related diseases (51%) and the need of development of prevention and health promotion (46.3%) as well as clinical medicine (32.8%). The inhabitants of the city recognize the resources of the city and the region in the field of medical sciences and health sciences as large and with high development potential.

CONCLUSIONS

The events organized as part of the European City of Science 2024 should become a good opportunity to promote and disseminate knowledge about the achievements and development potential of the City and the Region in the field of medical and health sciences.

No more than "half prevention": A qualitative study on psychosocial determinants of Covid-19 vaccination acceptance

Vaccine hesitancy represents a major barrier to achieving Covid-19 vaccination coverage, including in Italy, where the vaccination rates suggest that Covid-19 vaccination has not been fully integrated into people's routine immunization schedules. While quantitative studies have generated ample data on factors influencing vaccination decisions, rarely was an overall picture of people's actual views and experiences with Covid-19 vaccines provided. To address this gap, this qualitative study aimed to explore, from a psychosocial perspective, the relationships between perceptions of Covid-19 vaccines, traditional vaccines, and general approaches to prevention. Following a Grounded Theory approach, we interviewed 25 Italian adults from different socioeconomic and working backgrounds. Findings revealed that, despite a generally positive attitude towards Covid-19 vaccines, they were often regarded as providing only partial protection-a "half prevention"-against the disease rather than a definitive preventive measure. In this sense, a gap emerged between the overall notion of prevention and the specific representations associated with Covid-19 vaccines. Therefore, to increase vaccination acceptance, interventions should prioritize the reduction of such a gap by promoting the idea that vaccination against Covid is, in all respects, a safe and effective preventive tool. This requires fostering a credible knowledge system and building trustful relationships among community members and stakeholders involved in the vaccination campaign, including general practitioners, healthcare professionals, and political authorities.

Testing an extended theory of planned behaviour in predicting Covid-19 vaccination intention over the course of the pandemic: A three-wave repeated cross-sectional study

Background

Mass vaccination against Covid-19 has been recognised as the most effective strategy for overcoming the pandemic emergency and remains crucial in the ongoing efforts to mitigate the impact of the virus. The present study aimed to test the efficacy of an extended Theory of Planned Behaviour (TPB) model in predicting vaccination intention in three different phases of the pandemic. Understanding how psychological drivers of vaccine acceptance may have changed throughout the pandemic is essential for informing public health strategies and addressing vaccine hesitancy, even in the current post-pandemic context.

Methods

Using a repeated cross-sectional survey, we tested the hypothesised extended TPB model (intention, attitude, subjective norms, perceived behavioural control, anticipated affective reactions, risk perception, trust in science, trust in institutions and religiosity) across three independent samples: before (T1: November-December 2020; N = 657), during (T2: March-May 2021; N = 818), and after (T3: February-March 2022; N = 605) the start of the vaccination campaign in Italy.

Results

Results indicated significant differences between the time points in all investigated variables, pointing to a general trend of improvement in vaccine acceptability levels at T2 compared to T1, and a worsening at T3 compared to the other two time points. Interestingly, net of these differences, a multi-group Structural Equation Modeling analysis supported the invariance, across time, of the structural relationships examined within the extended TPB.

Conclusion

Findings demonstrated the efficacy of the TPB in predicting Covid-19 vaccination intention at different stages of the pandemic, suggesting that the model, in its extended version, represents a valuable framework for designing interventions aimed at promoting vaccine acceptance.

COVID-19 vaccine uptake, conspiracy theories, and health literacy among Black individuals in Canada: Racial discrimination, confidence in health, and COVID-19 stress as mediators

Factors influencing vaccine uptake in Black individuals remain insufficiently documented. Understanding the role of COVID-19 related stress, conspiracy theories, health literacy, racial discrimination experiences, and confidence in health authorities can inform programs to increase vaccination coverage. We sought to analyze these factors and vaccine uptake among Black individuals in Canada. A representative sample of 2002 Black individuals from Ontario, Quebec, Alberta, Nova Scotia, New Brunswick, British Columbia, and Manitoba, aged 14 years or older completed questionnaires assessing vaccine uptake, health literacy, conspiracy theories, racial discrimination experiences, COVID-19-related stress, and confidence in health authorities. Mediation analyses were conducted to assess (1) the effect of health literacy on COVID-19 vaccination uptake through confidence and need, COVID-19 related traumatic stress, and racial discrimination, and (2) the effect of conspiracy beliefs on COVID-19 vaccination uptake through the same factors. Overall, 69.57% (95% confidence interval, 67.55%-71.59%) of the participants were vaccinated and 83.48% of them received two or more doses. Those aged 55 years and older were less likely to be vaccinated, as well as those residing in British Columbia and Manitoba. Mediation models showed that the association between health literacy and COVID-19 vaccine uptake was mediated by confidence in health authorities (B = 0.02, p < 0.001), COVID-19-related stress (B = -0.02, p < 0.001), and racial discrimination (B = -0.01, p = 0.032), but both direct and total effects were nonsignificant. Lastly, conspiracy beliefs were found to have a partial mediation effect through the same mediators (B = 0.02, p < 0.001, B = -0.02, p < 0.001, B = -0.01, p = 0.011, respectively). These findings highlight the need for targeted interventions to address vaccine hesitancy and inform approaches to improve access to vaccinations among Black communities.

Vaccine-induced and hybrid immunity to SARS-CoV-2 after three or four doses of BNT162b2 - results from 22 months follow-up of a healthcare workers cohort, Israel, 2020-2022

OBJECTIVES

SARS-CoV-2 remains a global health concern 3 years after its emergence. Safe and effective vaccines mitigate the pandemic impact, but the optimal schedule remains unclear, especially in a context where a high proportion of the population is infected.

METHODS

We periodically measured anti-spike SARS-CoV-2 immunoglobulin (Ig)G titers using a quantitative assay in an Israeli healthcare worker cohort who all received at least two BNT162b2 doses and either received further doses and/or were subsequently infected up to 22 months after dose two, and compared geometric mean concentrations according to number of doses received and infection status using analysis of variance.

RESULTS

Among the 993 included participants, infection after dose two led to higher geometric mean concentration IgG titers than a third dose (4285 vs 2845 arbitrary unit/ml 1-2 months after infection/vaccination, P = 0.03). In 16-18 months after dose two, those infected and those who received three or four vaccine doses all had IgG geometric mean concentration levels above 500 arbitrary unit/ml with no significant differences among groups (P = 0.6). IgG levels plateaued 16-22 months after dose two.

CONCLUSION

Three BNT162b2 doses provide long-term immunogenicity comparable to breakthrough infection after dose two. Dose four transiently increases IgG levels and may be especially important for providing additional protection to vulnerable individuals during periods of increased transmission risk.

Political orientation, trust and discriminatory beliefs during the COVID-19 pandemic: Longitudinal evidence from the United Kingdom

The COVID-19 pandemic has impacted the world in many ways; for example, evidence from the United Kingdom indicates that higher rates of discriminatory behaviours against immigrants have been recorded during this period. Prior research suggests that political orientation and trust are instrumental in discriminatory beliefs against immigrants. A longitudinal study (six waves and a follow-up) was conducted in the United Kingdom during the COVID-19 pandemic (September 2020-August 2021) using convenience sampling (N = 383). The hypotheses enquired about whether political orientation predicts trust in government, trust in science and discriminatory beliefs. Multilevel regression and mediation analyses were conducted, using repeated measures nested within individuals. It was found that conservative views are associated with higher discriminatory beliefs, lower trust in science and higher trust in government. Furthermore, trust in science promotes reduction of discrimination, whereas trust in government, increases discriminatory beliefs. However, a nuance revealed by an interaction effect, shows that a positive alignment between political and scientific authorities may be required to reduce prejudice against immigrants. Exploratory multilevel mediation showed that trust is a mediator between political orientation and discriminatory beliefs.
