Fake news, WhatsApp e a vacinação contra febre amarela no Brasil

This article adopts an ethnographic perspective to analyze how users of the Brazilian Unified Health System consume and share information about vaccination, as well as their level of trust in this public-health practice. During the end of 2017, we conducted several interviews with people who were in line to get vaccinated against yellow fever. By interviewing subjects in this particular situation, we noted some acute changes in the contemporary regime of truth. Our conclusion was that online communication networks hybridize with other existing socialization processes, especially religious beliefs, making trust in circulating information more reliant on conviction than persuasion.
