The assertion that the FDA intentionally withheld known COVID‑19 vaccine risks is contradicted by a clear record of timely, publicly accessible warnings (including EUA fact‑sheet updates in June 2021 and expanded label requirements in 2025). FDA’s Emergency Use Authorizations (EUAs) for both the Pfizer–BioNTech and Moderna mRNA vaccines include explicit “Warnings and Precautions” sections describing myocarditis and pericarditis risks.
Though there is some risk of post-vaccine myocarditis (roughly 25-300 cases per million, depending on risk group), though it should be noted that this rate is far lower than the risk of getting myocarditis through the SARS-CoV-2 virus itself (roughly 1,500 cases per million), according to research published by the NIH. Causal attribution requires case‑level investigations (e.g., autopsy reports, medical examiner findings) showing that a failure to disclose a risk led directly to a death. With a lack of those to go off of, the second part of this claim is unverifiable.
