EU drug regulator: mRNA COVID vaccines do not cause absence of menstruation

Available data suggest that mRNA COVID-19 vaccines do not cause an absence of menstruation, the European Union's health regulator concluded on Friday. The assessment was prompted by reports of menstrual disorders after receiving one or two shots of either the Moderna (MRNA.O) or the Pfizer-BioNTech (PFE.N)(22UAy.DE) vaccines. Menstrual disorders can occur due to a range of reasons, including underlying medical conditions as well as stress and tiredness. Health authorities have highlighted that cases have also been reported following COVID-19 infection.
