Mathematically impossible claim about vaccines and miscarriages persists online

High Impact
Misinformation

A well-known anti-vaccine physician repeated the false claim that COVID-19 vaccines caused a 4,070 percent increase in miscarriages and stillbirths. This increase would mean that pregnancy losses far outnumbered pregnancies. The post was recently shared thousands of times and is the latest example of large accounts promoting this fake statistic.

The high profile and widespread nature of the misinformation elevates its risk. Emphasizing that dozens of studies in multiple countries have shown that COVID-19 vaccines have no negative impact on pregnancy outcomes is recommended. Debunking messaging may also emphasize that all available evidence shows that COVID-19 vaccination is safe for those who are pregnant or plan to become pregnant.
