A study has found a plausible link between changes in the menstrual cycle and COVID-19 vaccination.

Since the onset of vaccination drive around the world, various studies have pointed towards fears of decreased fertility due to Covid vaccination.

According to an editorial published in the peer-reviewed British Medical Journal, Victoria Male, a reproductive specialist at Imperial College London, UK noted that periods or unexpected vaginal bleeding are not listed as common side effects of COVID-19 vaccination.

So far, over 30,000 such reports had been made to the UK Medicines and Healthcare Products Regulatory Agency (MHRA) surveillance scheme for adverse drug reactions by September 2.

The expert notes that most people find that their period returns to normal the following cycle. Also, there is no evidence that COVID-19 vaccination adversely affects fertility.

“One important lesson is that the effects of medical interventions on menstruation should not be an afterthought in future research,” Ms Male said.

However, MHRA states that its surveillance data does not support a link between changes to menstrual periods and COVID-19 vaccines.

As the number of reports is low in relation to both the number of people vaccinated and the prevalence of menstrual disorders generally.

In the editorial, Ms Male argues that approaches better equipped to compare rates of menstrual changes in vaccinated versus unvaccinated populations are needed.

This suggests that, if there is a connection, it is likely to be a result of the immune response to vaccination, rather than to a specific vaccine component, Ms Male adds.

The editorial also mentions that the menstrual cycle may be affected by the body’s immune response to the virus itself.
