"It's not something that people, in my opinion, should be afraid. Because the risks are weak and that the benefits of vaccination are overwhelming," said Lemos.

In a statement following the meeting, the ACIP said something similar. "The facts are clear: it's aExtremely rare side effectAnd only an extremely small number of people will experiment after vaccination, "they said." Above all, for young people who do, most cases are light and individuals often recover by themselves or with treatment Minimal.
