40% of Women With The COVID Vaccine Have Reported Significant Effects on their Periods

Nearly half of women receiving a COVID-19 vaccine reported heavier menstrual bleeding, according to new research from the University of Illinois at Urbana-Champaign.

The figures come from a survey of over 35,000 women who were fully vaccinated, with the majority of the cohort receiving a Pfizer jab followed by Moderna.

“In this sample, 42% of people with regular menstrual cycles bled more heavily than usual, while 44% reported no change after being vaccinated,” summarized researchers, which counted funding from the National Institutes of Health (NIH) for the study.
