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: Joseph Ladapo


Claim: Florida public health data “strongly implies that thousands of Floridians died as a result of receiving Pfizer instead of Moderna.”


Rating: FALSE


Explanation: The Florida study found an association between vaccine brand and mortality in a matched observational cohort, but it did not establish that Pfizer caused deaths. Researchers said differences in underlying health or Moderna’s somewhat greater protection against COVID-19 could explain the results.
