Abstract:

This article presents the evolution of fake news disseminated about vaccines and the Sars-CoV-2 virus and this phenomenon\'s negative impacts on the health crisis that Brazil is going through. This is a quantitative empirical study, based on the notifications received by the Eu Fiscalizo app, through which the predominance of Instagram, Facebook, Twitter and WhatsApp platforms was identified as the main means of disseminating and sharing rumors and misinformation about to Covid-19. Large-scale circulation of fake news about vaccines was observed, directly related to Brazilian political polarization, which became prevalent four months after the first case of Covid-19 was recorded in the country. It is concluded that the phenomenon collaborated to discourage the adhesion of portions of the Brazilian population to social isolation and vaccination campaigns.
