This project aims to understand and analyze the determinants of vaccination coverage in the Brazilian territory by assessing its association with socio-economic factors, public health spending, coverage of primary health care and the Bolsa Família Program and the influence of patterns of content dissemination on immunization on social media. The results will be disseminated through virtual games, podcasts, interactive panels, infographics, an e-book for municipal managers, a webinar for undergraduate students in the health field and a seminar on World Immunization Day.
