Abstract

The impact of fake news reached the health area and distrust in relation to vaccines brought back diseases that had been eradicated. But how are these anti-vaccine discourses constructed in social medias? In this paper, 80 fake news stories focusing on vaccines were collected through Brazilian websites that perform debunking, a strategy for detecting and unmasking misinformation and fake news. From the application of an analytical protocol, the main characteristics present in the elaboration of these publications were mapped. Content analysis revealed that Facebook and WhatsApp are the preferred medias for this type of sharing. About 59% of the contents are totally false and most of the speeches highlight the risks of vaccines as a convincing strategy. The most referenced sources are supposedly doctors and scientists to create reliability. The survey also points out that 60% of publications have grammatical and spelling errors in the preparation of texts.
