1. Claim 1

   Misleading50% confidence▶ 0:04

   “claims 82% of women who got the COVID 19 vaccine during the first trimester suffered from suffered from miscarriages”

   The claim that 82% of women vaccinated against COVID-19 during the first trimester suffered miscarriages is false.

   The 82% figure came from dividing miscarriages among a selected group of completed pregnancies by an incomplete denominator. Fact-checkers and CDC data found no increased miscarriage risk and described the calculation as inappropriate.

   Omits: The calculation counted only a small subset of completed pregnancies, while most pregnancies among women vaccinated early were still ongoing and lacked follow-up; the underlying data also involved women vaccinated in the first or second trimester, not exclusively the first trimester.

   Checked twice, independently: the first pass returned False and the second Misleading. Recorded as Misleading.

     RefutesThis figure is based on an incorrect calculation.

   • 2CDC Data Thus Far Show COVID-19 Vaccination Safe During Pregnancy↗

     RefutesThe 82% miscarriage number, which does not appear in the study, is incorrect because it is based only on people who were vaccinated in their first or second trimesters and reported completing their pregnancies in the follow-up interviews conducted by March 30.

   • 3New CDC Data: COVID-19 Vaccination Safe for Pregnant People↗

     RefutesA new CDC analysis of current data from the v-safe pregnancy registry assessed vaccination early in pregnancy and did not find an increased risk of miscarriage among nearly 2,500 pregnant women who received an mRNA COVID-19 vaccine before 20 weeks of pregnancy.

2. Claim 2

   Accurate99% confidence▶ 0:10

   “which is a number you both know has been debunked”

   The 82% miscarriage figure has been debunked.

   Multiple independent fact-checks and the underlying study's authorship record have rejected the 82% figure as an improper calculation based on incomplete follow-up data.

     SupportsA claim we’ve seen circulating around miscarriages and the vaccine was that a study had shown 82% of pregnancies end with miscarriage following Covid vaccinations. This is wrong.

   • 2CDC Data Thus Far Show COVID-19 Vaccination Safe During Pregnancy↗

     SupportsHowever, this doesn’t lend any credence to the 82% figure, which is still an incorrect calculation — and is still circulating online in newer social media posts highlighting the CDC’s correction.
