The influence of information sources on COVID-19 vaccine acceptance in Bulgaria

This study examines the associations between preferred information sources, risk perception, and COVID-19 vaccine acceptance in Bulgaria. In April 2022, a cross-sectional study was conducted on a convenience sample of 1,200 Bulgarian residents using a self-administered online questionnaire. Bivariate statistical analyses revealed significant differences in information source choices between vaccine acceptors and non-acceptors. Obtaining information from health professionals, health officials, scientific publications, traditional media, and communities increased the odds of accepting vaccination. Respondents relying on credible sources were also less concerned about vaccine safety. The results did not show significant associations between social and Internet news media use, risk perceptions, and vaccine uptake. Providing accurate information based on scientific facts and dispelling misinformation have the potential to overcome vaccine hesitancy; thus, communication is an essential tool in promoting vaccination.
