By Shanet Susan AlexJul 18 2022Reviewed by Danielle Ellis, B.Sc. In a recent work published in the American Journal of Obstetrics and Gynecology, investigators analyzed the connections between severe acute respiratory syndrome coronavirus 2 vaccination and infection with menstrual health.

About the study In the present work, the researchers examined the correlations between COVID-19 vaccination and SARS-CoV-2 infection with alterations in the typical menstrual cycle features in pre-menopausal healthcare workers participating in an active prospective cohort investigation. Additionally, they looked at the length of such alterations, potential variations by vaccine kind, and whether stress brought on by the pandemic was responsible for variances in the usual menstrual cycle traits.

Results Related StoriesThe study results indicated that with a median follow-up length of 9.2 years, the median age of the study volunteers at research initiation and the completion of the follow-up was 33 years, ranging from 21 to 51, and 42 years, ranging from 27 to 56, respectively. The authors recorded 3,527 COVID-19 vaccinations, i.e., 91.4%, and 421, i.e., 10.9%, SARS-CoV-2 infections during follow-up.

Interestingly, SARS-CoV-2 infection was not linked with alterations in the regular menstrual cycle features. According to this inference, the transient impact of COVID-19 vaccines may vary from the immune reaction to SARS-CoV-2 infection, which seems more widespread and tissue-selective than those associated with vaccines. Nevertheless, given the study's small number of affected subjects, this finding should be interpreted carefully.
