Insufficient evidence to claim COVID-19 vaccines cause menstrual irregularities in vaccinated women; vaccinated people aren’t making unvaccinated people ill
Millions of women in the U.S. received at least one COVID-19 vaccine dose. No significant safety concerns related to fertility or pregnancy have emerged in clinical trials or safety monitoring of COVID-19 vaccination campaigns. For the moment, there isn’t sufficient evidence to establish a causal relationship between the COVID-19 vaccines and menstrual irregularities that women observed after vaccination. More studies are needed to shed light on this subject.
