Psychological correlates of attitudes towards COVID-19 vaccines among Polish respondents – a snapshot study before the start of the massive vaccination campaign

Background: COVID-19 vaccines are being recognized as a way to stop the ongoing pandemic. However, for this method to be effective, it requires a high level of people’s willingness to be vaccinated. In this context, measuring the psychological aspects of attitudes towards vaccination against COVID-19 when the vaccine was developed but not yet distributed was of interest. Method: In a study conducted on a sample of 468 Polish participants, we measured attitudes towards the COVID-19 vaccine in the context of such variables as fear of COVID, the general tendency to conspiracy ideation and conspiracy beliefs about COVID-19, knowledge about vaccines, attitudes towards science, previous protective behaviors during a pandemic, perceived infectability and germ avoidance. We also tested the association of attitudes towards the COVID-19 vaccine with participants’ experiences of the COVID-19 pandemic, gender, age, and level of education. Results: The analyses revealed correlations between attitudes towards the vaccine with most of the variables studied. A regression model with predictors such as fear of COVID, attitudes towards science, and conspiracy beliefs related to COVID-19 explained 46% of the variance of the attitudes towards the COVID-19 vaccine. Male participants were more positive about the COVID-19 vaccine than female participants. Attitudes towards the COVID-19 vaccine were not related to personal experiences of the pandemic, the age, and the level of education of participants. Conclusion: The obtained results show the importance of psychological aspects concerning attitudes towards vaccination, which can be considered in designing preventive public interventions.
