The COVID-19 Vaccine and the Menstrual Cycle

Health care workers answer questions about the COVID-19 vaccines.

Jessica Malaty Rivera, MS explains what we know about menstrual cycles and COVID-19 vaccines.

I know that in menstruating women, it has been reported to interrupt or cause irregular cycles. And that typically resolves in a few months. But, because of that, we have to remember too that our endometrium, that part of that lining of our uterus is actually part of our immune response. And, so, an irregular cycle or some weird spotting or some weird bleeding, it’s actually not that out of the norm.
