COVID-19 Vaccine And Your Menstrual Period

There are many reasons for your menstrual period to change, and you should seek a gynecologist’s advice if you are having issues with your period.

There has been some question as to whether vaccination against COVID-19 could disrupt a menstrual cycle.

A study published in the April 2022 Issue of OBSTETRICS & GYNECOLOGY looked at almost 4000 women with normal natural cycles and looked at the changes in cycles based on information on cycle length before an after vaccination.

In fact, for all three of the available vaccines, there was less than a one day change in menstrual period length.

Change in length of menstrual cycles is not associated with vaccination, and you shouldn’t use worry about a possible menstrual cycle effect as a reason to defer indicated vaccinations.
