COVID-19 vaccine hesitancy in eight European countries: Prevalence, determinants, and heterogeneity.

ABSTRACT: We examine heterogeneity in COVID-19 vaccine hesitancy across eight European countries. We reveal striking differences across countries, ranging from 6.4% of adults in Spain to 61.8% in Bulgaria reporting being hesitant.
