Based on a public consultation on science communication, we analysed citizens’ perceptions of adherence to vaccination, as well as postponement or refusal. Generational differences were found at different levels of knowledge about vaccination, which may lead to different atti-tudes. The reports collected reveal concerns about the emer-gence of alternative practices to vaccination and their possible expansion. They also point to the centrality assumed both by the sources of information selected and by the communication flows carried out with health professionals when it comes to decisions based on scientific evidence.174153porpostponementpublic healthrefusalVaccinesHistorySocial Sciences (miscellaneous)Political Science and International RelationsSDG 3 - Good Health and Well-beingjournal article10.31447/35450https://www.scopus.com/pages/publications/105019920122
