Is there any credible theory about how COVID-19 vaccines may disrupt menstrual cycles?
Experts say that there is currently not enough evidence to establish any clear links between the COVID-19 vaccine and various disruptions to the menstrual cycle. A number of women have shared on social media anecdotes about disruptions or changes they’ve experienced after getting a vaccination.
Baylor medical professor Dr. Mark Turrentine tells Health magazine that there is “no biologic mechanism” that would account for the kinds of changes being discussed. He notes that no menstruation-related issues have surfaced in clinical trials for the vaccines or in “adverse event” reporting since the administration of vaccines at scale began.
An anthropology professor at the University of Illinois has launched a survey to collect reports from women observing any changes (or the lack thereof) in their menstrual cycles post-vaccine.
