According to Anvisa, cases of thrombosis syndrome with thrombocytopenia (which involves blood clots) related to adenovirus immunizers are very rare and usually occur after exposure to the first dose of this type of vaccine. The agency also stated that it will continue to carry out a continuous assessment of the benefit-risk balance of all vaccines authorized in Brazil.

When there was a meeting with representatives of the Food and Drug Administration (FDA), the regulatory agency of the United States, Anvisa came to be informed that there would be no concern about the safety of the Janssen vaccine. However, the FDA understands that other immunizers should be prioritized in the North American country.
