Even if people s expressed willingness to get a vaccine SARS-CoV-2, as gauged in global surveys, translates perfectly into vaccine uptake, it is still likely that vaccine hesitancy will impact the vaccination effort against SARS-CoV-2. The aim of this review was to identify and synthesise evidence relating to effective messaging for encouraging vaccination in order to prevent virus transmission during pandemics or epidemics, including COVID-19. In light of evidence of the promise that involving key stakeholders in the design of public health messaging holds (e.g., by fostering co-creation of materials with the understanding of those we wish to engage in target behaviours), the review also examines patient and public involvement (PPI).
