The Effect of Science-Related Populism on Vaccination Attitudes and Decisions

As the COVID-19 pandemic has sadly shown, the decision against vaccination is often linked to political ideologies and populist messages among specific segments of the population: People do not only have concerns about a potential health risk associated with vaccination but seem to have also adopted more populist attitudes towards science. In this study, the relationship between science-related populism and individuals’ attitudes towards vaccination was examined, presuming that scientific-related populism also influences individual responses towards different vaccinations. As different types of diseases and their vaccines might be perceived rather distinctively by the public, different vaccinations were considered. The survey is based on responses from 870 people from Germany and Austria. Results indicate that science-related populism influences responses towards some vaccination types, especially for those that receive extensive media coverage such as COVID-19 and measles (MMR). There was no significant impact of science-related populism on individuals’ vaccination intentions for other vaccines like seasonal influenza, human papillomavirus, or tick-borne encephalitis. In conclusion, limitations and directions for future research are addressed.
