Together with the José Luiz Egydio Setúbal Foundation, researchers from Democracia em Xeque analyzed false information about vaccination, in particular childhood vaccination, on YouTube, Instagram, TikTok, X/Twitter, Telegram and WhatsApp. These analyzes gave rise to reports identifying the main arguments, analysis of the actors involved and suggestions for action. In addition to the delivery of these reports and regular presentations to the Foundation's team, a compilation of studies arising from this partnership was presented at the 5th Public Policy Forum on Childhood Health, held at the Butantan Institute, in São Paulo, on October 24, 2023 .
