Fact Check: Did Fauci privately admit COVID-19 vaccines were associated with first-trimester miscarriage?

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: Rand Paul (R)


Claim: Fauci privately admitted concerns about COVID-19 vaccine side effects “associated with miscarriage in the 1st trimester,” while publicly saying there was nothing to worry about.


Rating: MISLEADING


Explanation: Fauci’s January 2021 texts mentioned a theoretical concern about fever after vaccination, but he also noted that no safety red flags had emerged and that pregnant people should weigh the risks and benefits. Later data did not show an increased risk of miscarriage from COVID-19 vaccination.
