ObjectivesThe aim of this study was to explore factors that influence individuals' attitudes towards mandatory vaccination in Greece.MethodsA nationally representative cross-sectional telephone survey was conducted via a random multistage selection process in October 2019 in Greece. The survey was designed to obtain information about whether vaccination should be mandated or not among adults 18 years of age or older. A multivariable logistic regression model was used to estimate the association between individuals' sociodemographic, contextual and clinical characteristics, utilization, satisfaction, and trust in the healthcare system and providers and their preference over mandatory vaccination.ResultsA total of 901 participants fully completed the survey (response rate 90%-901/1001). About 85% of the respondents supported mandatory vaccination. Individuals who used preventive services more often compared to those who never or rarely used such, those who reported increased trust in official healthcare authorities' guidelines and recommendations compared to those who reported no trust and those who had underage children living in the household were significantly more likely to support mandatory vaccination. No differences were observed for sociodemographic factors and mandatory vaccination support.ConclusionThis survey revealed that most Greek citizens support mandatory vaccination, which was critically affected by the utilization of preventive services and trust in healthcare authorities. Our results suggest that healthcare policy interventions should promote mandatory vaccination through multi-level initiatives to improve healthcare providers' and the general public's understanding of the value of vaccination.© 2021 John Wiley & Sons Ltd.
