Health Canada says there is a possibility that COVID-19 vaccination causes menstrual issues but it doesn’t know how prevalent it is among women.
“Based on the available evidence, and in the context of the frequency of menstrual irregularities, it is not possible to determine what percentage of COVID-19 mRNA vaccine recipients could experience an increase in menstrual bleeding,“ Health Canada said in a Sept. 18 Inquiry of Ministry tabled in response to questions submitted by Conservative MP Ted Falk.
