False Claims About Miscarriage Risk From Covid-19 Vaccines Are Spreading Online. They Use a Faulty Interpretation of Data

Later studies found no increased miscarriage risk after COVID-19 vaccination, even as Johnson cited a misread 2021 study to back the claim.

  • On Monday, U.S. Senator Ron Johnson of Wisconsin revived inaccurate claims that COVID-19 vaccines cause an 82% miscarriage rate, citing a misinterpreted 2021 study and newly released text messages from former health official Dr. Anthony Fauci.
  • The 82% figure stems from a flawed 2021 analysis that erroneously excluded 700 third-trimester pregnancies from its denominator; researchers later corrected this error, confirming miscarriage rates fell within the typical 10% to 20% range.
  • Research involving over 1 million pregnancies worldwide consistently demonstrates vaccine safety; a 2023 analysis of more than 123,000 pregnancies found no increased miscarriage risk, according to Dr. Krutika Kuppalli, an infectious disease doctor at the University of Texas Southwestern Medical Center.
  • Dr. Brenna Hughes, chair of the Society for Maternal-Fetal Medicine's Infectious Disease and Emerging Threats Committee, warned that reviving this misinformation risks leaving pregnant women with broader doubts about essential medical interventions.
  • The release of Fauci's texts by Johnson and Senator Rand Paul of Kentucky aims to challenge the former health official's pandemic-era leadership, though experts emphasize vaccination benefits significantly outweigh risks like sore arms or fatigue.
