Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.

Claimant: Steve Kirsch

Claim: The Florida study shows “the Pfizer vaccine was not safe” and “it killed people.”

Rating: FALSE

Explanation: The study did not compare vaccinated people with unvaccinated people and cannot determine whether either vaccine increased overall mortality. Experts said the findings show only an association between Pfizer and Moderna recipients, not proof that Pfizer caused harm.
