Women Experience Alteration of Menstrual Cycles After COVID Vaccination
July 18th, 2022Via: Miami Herald:
With more than 222 million people in the U.S. fully vaccinated against the coronavirus, some reports, as well as questions, have emerged about the vaccines’ potential effects on the body — including on menstrual cycles.
One dose of a COVID-19 vaccine was found to temporarily alter menstruation and was linked to a slightly longer cycle in a study published in January, McClatchy News previously reported. This work received funding from the National Institutes of Health.
Months later, another study has found menstrual cycles may temporarily change after a person gets a COVID-19 vaccine.
Thousands of people who received two COVID-19 vaccine doses experienced a change in their typical periods, including heavier periods or breakthrough bleeding, according to a study published July 15 in the journal Science Advances. The work also received NIH funding.
Of those with regular periods, 42% said they had heavier bleeding after at least one dose of a COVID-19 vaccine, the study found. In comparison, about 44% reported their flow did not change. Additionally, roughly 14% experienced a mix of a lighter flow or no change.
