Mediation Analysis of the Relationship Between Health Literacy and the French General Population’s Opinions on Hepatitis B Vaccination: Representative Cross-Sectional Survey of the SLAVACO Project

Enhancing HL might positively influence hepatitis B vaccination opinions and uptake through greater trust in the health care system. From a public health perspective, strategies should go beyond providing clear information and access to vaccines and actively work to strengthen trust in health care institutions and professionals. National campaigns correcting misconceptions about hepatitis B vaccination could be complemented by targeted interventions for groups most likely to hold negative opinions. Repeating this survey in the post-COVID-19 context could also reveal different trends, given evolving public perceptions of vaccines and health authorities.
