Prevalence and sociodemographic correlates of COVID-19 vaccine acceptance in 20 European countries

Abstract Our study aimed to analyze the prevalence and socio-economic factors associated with COVID-19 vaccine hesitancy using individual data from representative national samples of 20 European countries. Data from round 10 of the European Social Survey, collected from May 2021 to September 2022, were analyzed. Prevalence (with a 95% confidence interval (CI 95%)) of participants’ intention to get vaccinated against COVID-19 was calculated. Crude differences in vaccine hesitancy proportions across sociodemographic strata were assessed using the Chi-square test. There were 31,771 adult participants (46.0 % men). The percentage of those hesitant (i.e. those who were not already vaccinated and intended not to be) toward the COVID-19 vaccine was 18.0% (CI 95% 17.6 - 18.4). Men and women were equally hesitant (18.0% vs. 18.0%, p = 0.93). There were differences between those under 40 (22.9%), adults between 40 and 59 (18.1%), and those over 60 (14.3%, p < 0.001). The unemployed had a higher proportion of hesitancy (32.9%) compared to the employed (17.4%), retirees (14.8%), and students (21.1%, p < 0.001). People living in rural areas have higher levels of hesitancy compared to those in urban areas (19.3% vs. 17.3%, p < 0.001). The estimates indicate that the highest prevalence of vaccine hesitancy was in Bulgaria (61.6%), Slovenia (40.4%) and Slovakia (30.7%), while Iceland (2.3%), Portugal (3.6%) and Italy (4.0%) had the lowest. Our study confirms high prevalence and high variability of hesitancy towards COVID-19 vaccines in Europe and identify groups for potential targeted interventions.
