No Evidence COVID-19 Vaccines Increase Miscarriage Risk, Fact-Check Finds

TL;DR
PolitiFact debunks Sen. Ron Johnson’s claim that COVID-19 vaccines cause an 82% miscarriage rate, showing the statistic came from miscounting the denominator in a 2021 v-safe study; when correctly calculated, the miscarriage rate was about 12.6% initially, with follow-ups showing a cumulative risk around 12.8–14.1%, within the normal range. Fauci’s texts reveal early theoretical concerns rather than data proving risk, and numerous large studies find no increased miscarriage risk from vaccination.
