[Vaccine hesitancy: How to lift the brake?]

Abstract

Introduction: We are at a "post-trust" period, characterised by vaccine hesitancy which is being widely diffused by the media and social networks. The consequences of this include: measles, whooping cough epidemics, vaccine coverage decreasing for the youngest, and remaining at low levels in adults. Mandatory vaccination has been extended for children less than two years in France, with the objective to increase vaccination rates during this period.

State of the art: The medical literature on this topic is increasing, mainly regarding descriptions of reasons for vaccine hesitancy. These include doubt about vaccine efficacy, safety, and real need as well as with regard to social aspects, cultural, religious beliefs. The literature that explores the best way to address vaccine hesitancy is still scarce. Healthcare workers are a key in promoting vaccine acceptance. There is a need to address the issue of vaccine hesitancy in a multicompartmental way. Health authorities must communicate in a clear and concise style that is trust-based and science-informed, being transparent both on vaccine benefits and on issues around vaccine safety. For caregivers, motivational interviewing can help patients change behaviour.

Conclusion: Anti-vaccine ideas were born with vaccines; they are abundantly spread through the Internet and social networks and can give a false impression of their basis in reality. It is time for positive action not merely a defensive approach.
