Vaccine hesitancy in the French population in 2016, and its association with vaccine uptake and perceived vaccine risk-benefit balance

Abstract

BackgroundVaccine hesitancy (VH) is prominent in France. Objectives: This study aimed to estimate the prevalence and socio-demographic correlates of VH in sub-groups of the French population and to investigate the association of VH with both vaccine uptake and perceived risk-benefit balance (RBB) for four vaccines. Methods: During the 2016 Health Barometer - a national cross-sectional telephone survey in a representative sample of the French population - parents of 1-15 year-old children, parents of 11-15 year-old girls and elderly people aged 65-75 years were asked about VH (using three questions adapted from the World Health Organization definition), vaccine uptake and perceived RBB for measles and hepatitis B (children's parents), human papillomavirus (girls' parents) and seasonal influenza (elderly people) vaccines. Results: A total of 3,938 parents including 959 girls' parents - and 2,418 elderly people were interviewed. VH prevalence estimates were 46% (95% confidence interval (CI): 44-48) among parents, 48% (95%CI: 45-51) among girls' parents and 35% (95% CI: 33-36) among elderly people, with higher estimates associated with high education level, children's age (10-15 years), and, for the elderly, poor perception of health status. VH was associated with uncertainty about and/or an unfavourable perception of vaccines' RBB for the four vaccines and with lower self-reported vaccine uptake, except for human papillomavirus vaccine in girls. Results were confirmed by multivariable analysis. Conclusion: Further research is needed to study the association between VH and vaccine uptake for other vaccines, and to design and validate measurement tools to monitor VH over time.
