Unraveling COVID-19 vaccine hesitancy in Europeans 50 and older through a lens of preventive practices.

Background: The COVID-19 pandemic underscored the issue of vaccine hesitancy, leading researchers to study the determinants of people's willingness to receive the COVID-19 vaccine. This study is the first to comprehensively investigate the role of preventive practices at both the individual and contextual level, drawing on the theoretical concept of "cultural health capital".
Methods: Utilizing data from the Survey of Health, Ageing, and Retirement (SHARE), covering information from 18,454 individuals aged 50 years and above residing in 25 European countries, we examined the influence of past engagement in preventive practices and the prevalence of such practices within a country on the likelihood of COVID-19 vaccine uptake. Our analysis included (i) previous vaccination behaviors, (ii) other healthcare-related behaviors, and (iii) lifestyle factors at both the individual and contextual levels. Leveraging the longitudinal design of the SHARE, we accounted for the temporal ordering of the relationships.
Results: At the individual level, almost all preventive behaviors were significantly related to people's willingness to receive the COVID-19 vaccine. Individuals who (i) had received an influenza vaccination prior to the COVID-19 outbreak and during childhood, (ii) had regularly participated in dental and blood pressure check-ups throughout their lives, and (iii) did not engage in lifestyle-related risk behaviors, were more likely to accept the COVID-19 vaccine. Notably, alcohol use was not significantly associated. At the contextual level, only the vaccination coverage rate for influenza was found to be robustly related, indicating that individuals were more inclined to receive the COVID-19 vaccine in countries with higher influenza vaccination rates prior to the pandemic.
Conclusion: Active participation in preventive practices and effective implementation of vaccination campaigns can contribute to the development of (institutional) cultural health capital, which ultimately promotes a greater willingness to get vaccinated against COVID-19.
