The European Medicines Agency (EMA) said it has insufficient evidence to suggest that there is a causal relationship between mRNA COVID-19 vaccines and missed periods.
The EMA's Pharmacovigilance Risk Assessment Committee ("PRAC") said it evaluated data from reports to the EudraVigilance adverse events databases as well as literature findings.

The PRAC added the available data does not support an update of the labeling for Pfizer (NYSE:PFE)/BioNTech (NASDAQ:BNTX) or Moderna's (NASDAQ:MRNA) shots.
The PRAC also said it is continuing to look into cases of heavy menstrual bleeding associated with the mRNA shots.
The EMA began investigating cases of menstrual disorders with the mRNA vaccines in February.
