How to report adverse effects of vaccines?
To facilitate the notification of adverse effects of vaccines and medications, Anvisa has launched a new form. In this way, the agency seeks to facilitate and streamline the citizen’s report on suspicions of these events. This is because people who are not health professionals can access the channel.
The space is intended for users to report “suspected problems during treatment, such as adverse reactions, absence or reduction of the effect , medication errors, interactions between different medications and use with a different purpose than indicated in the package insert (off label)”. In addition, those who write can notify a fact even without the certainty that it was a drug or vaccine that caused the problem.
