The claim
Vacinas contra a Covid matam
Original review summary
The review found that a viral post used an edited 2018 TV report about deaths after yellow-fever vaccination to imply that the report concerned COVID vaccines. The original report discussed yellow fever, and the review says the edits changed both the video and its caption; the presenter did not say that COVID vaccines kill.[S1]
Additional context
The report at the center of the post was from 2018; Brazil’s COVID vaccination began in 2021. [S1]
