Getting vaccinated against Covid-19 does not make women more likely to seek medical attention for menstrual problems, the largest study conducted on the subject said on May 4 (2023).

Since Covid vaccination campaigns began nearly two and a half years ago, some women have reported changes in their menstrual cycle after getting the mRNA (messenger ribonucleic acid) shots from Pfizer/BioNTech and Moderna.
