A European Medicines Agency ("EMA") safety committee is investigating cases of menstrual disorders seen with mRNA COVID-19 vaccines made by Pfizer (NYSE:PFE)/BioNTech (NASDAQ:BNTX) and Moderna (NASDAQ:MRNA).
The EMA's Pharmacovigilance Risk Assessment Committee is conducting the inquiry in light of spontaneous reports of menstrual disorders -- notably heavy bleeding -- with both vaccines and finding in scientific literature.

The safety committee previously analyzed reports of menstrual disorders as it was evaluating safety summary reports for the shots and concluded at that time the evidence didn't indicate a causal link between the vaccines and the disorders.
The EMA added there is no evidence to suggest that the mRNA shots impact fertility.
