The Fake 82% Miscarriage Rate Four Senators Pinned on Fauci

The 82% figure is a real number pulled from a real study — just calculated wrong. The underlying research is a New England Journal of Medicine paper (Shimabukuro et al., published April 2021) that tracked 3,958 pregnant people enrolled in the CDC's v-safe registry after COVID-19 vaccination ^[1]. By the study's cutoff, 827 of those pregnancies had reached a completed outcome, and 104 ended in miscarriage — a 12.6% rate, squarely inside the normal background range for pregnancy loss ^[1][3].

To manufacture "82%," the senators narrowed the denominator to just the 127 women who were vaccinated in the first or second trimester and whose pregnancies had already concluded by the time the data was pulled — while discarding roughly 700 women vaccinated in the third trimester, who by definition could not yet have miscarried and whose ongoing pregnancies simply hadn't been counted ^[1][3]. Divide 104 by 127 instead of by the full study population and you get 81.9%, rounded up to "82%." The number is real; the comparison it's built on is not.

Follow-up research settled the question. A September 2021 study put cumulative miscarriage risk at 12.8–14.1% ^[1]; the CDC's final analysis, published in February 2026, tracked 12,097 vaccinated people and found a 10.79% rate — "no increased risk" compared with unvaccinated pregnancies ^[2]. More than a million pregnancies have since been studied, and none show an elevated miscarriage rate tied to COVID-19 vaccination ^[1].

This isn't a fringe account — it's four sitting members of Congress. Johnson and Paul released the texts and framed them as proof of a cover-up ^[2]; McClain misattributed the number directly to a peer-reviewed journal ^[2]; Cruz turned it into a podcast headline and an X post that racked up more than 600,000 views before he quietly deleted it roughly a day later ^[3].

Cruz's post didn't go unchallenged — X's Community Notes system attached a correction within hours: "The post misrepresents a 2021 CDC/NEJM study (Shimabukuro et al.). The 82 percent miscarriage figure excludes ~700 of 827 participants with incomplete follow-up; full data shows ~12.6 percent rate, within normal background (10-26 percent). Large analyses confirm no increased risk" ^[3]. A platform-native fact-check outran a U.S. senator's own deletion button.

FALSE. PolitiFact rated Johnson's claim False ^[1]; FactCheck.org concluded the senators "twist" Fauci's texts and revive a "false miscarriage statistic" ^[2]; HuffPost's independent math check reached the same conclusion ^[3]. Fauci's actual text — flagging a theoretical concern about cytokine-driven fever after a second dose, sent in January 2021 before broad real-world data existed — is real, but it is not the data-suppression smoking gun it's being sold as ^[2].

Absence of a cover-up is not the same as absence of caution: Fauci raised a hypothesis in private, and months of public data since have closed the question — COVID-19 vaccination does not raise the risk of miscarriage. The 82% figure will keep circulating because it's a punchier number than 12.6%, but every study since 2021 says what the CDC said again in February 2026: no increased risk ^[2].
