The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-sectional online survey was conducted during the first wave of the pandemic, involving 6697 respondents across 20 countries. Results showed that 72.9% of participants reported positive intentions to be vaccinated against COVID-19, whereas 16.8% were undecided, and 10.3% reported they would not be vaccinated. At the individual level, prosociality was a significant positive predictor of vaccination intentions, whereas generic beliefs in conspiracy theories and religiosity were negative predictors. Country-level determinants, including cultural dimensions of individualism/collectivism and power distance, were not significant predictors of vaccination intentions. Altogether, this study identifies individual-level predictors that are common across multiple countries, provides further evidence on the importance of combating conspiracy theories, involving religious institutions in vaccination campaigns, and stimulating prosocial motives to encourage vaccine uptake.

Objective: Vaccine hesitancy remains a significant public health challenge, and one that is socially patterned. This study examined whether the vaccine hesitancy effects of identifying as female, race–ethnicity, the number of children, educational attainment, and political conservatism were mediated by governmental conspiracy beliefs. Methods: Linear mediation models controlling for potential confounders were employed to analyze data from a national survey of adults (2019 Chapman University Survey of American Fears; n = 1,209). Results: Effects on vaccine hesitancy were significant and negative for educational attainment, and significant and positive for the other focal predictors. Governmental conspiracy beliefs significantly mediated each of these effects; the percent mediated was largest for Hispanic identity (79 percent), followed by female identification (69 percent), educational attainment (69 percent), number of children (55 percent), black identification (34 percent), and political conservatism (30 percent). Conclusion: This study underscores the importance of nonvaccine-related conspiracy beliefs for future interventions aimed at reducing sociodemographic disparities in vaccine hesitancy.

Conspiracy Theories and Politics in Slovakia: How Conspiracy Thinking Relates to Political Opinions and Preferences Katarína Kondrótová Abstract (English) Conspiracy theories have become a fashionable buzzword, appearing across the internet, the media, and political speeches with great frequency. However, there are many misconceptions associated with them, making them more divisive and mysterious than they need to be. The present contribution seeks to remedy that by providing a deep dive into conspiracy theories. It examines the multitude of their possible definitions and conceptualizations, their existence across history, as well as past research findings about why they appeal to us. In the second half, conspiracy theories are presented through new research regarding their relation to political and ideological preferences of Slovaks. The findings are in line with past studies, showing a relationship between stronger conspiracy beliefs and extremist thinking, preference of authoritarian policies, and low faith in authorities. A regression analysis also uncovered a strong correlation between conspiracy beliefs and the political party the respondents had voted for, as well as their preference of the politics and ideologies of 'the West' (EU, USA) or 'the East' (Russian federation).
