Fake News and vaccine hesitancy in the COVID-19 pandemic in Brazil.

This paper presents the evolution of fake news disseminated about vaccines and the SARS-CoV-2 virus and its adverse impacts on the current Brazilian health crisis. This quantitative, empirical study is based on the notifications received by the Eu Fiscalizo app, through which the Instagram, Facebook, Twitter, and WhatsApp platforms were identified as the principal means for disseminating and sharing rumors and misinformation about COVID-19. We observed large-scale circulation of fake news about vaccines directly related to the Brazilian political polarization, which became prevalent four months after the first COVID-19 case was recorded in the country.
