Five teams will begin investigating a possible link between irregular menstrual cycles and the COVID-19 vaccine later this year due to reports of irregular periods after taking the vaccine.
Some of the symptoms patients describe include painful periods, irregular menstrual cycles, and heavy bleeding.
So far, there is no direct link between the vaccine and irregular menstrual cycles; however, no one investigated the possibility during the trial of the vaccine.
Because of this insufficient data, teams at Johns Hopkins University, Harvard Medical School, Boston University, Michigan State University, and Oregon Health and Science University will conduct studies of people of all ages and backgrounds who have not received the vaccine in order to study the cycles before and after the shot.
Periods, including the length and flow of a menstrual cycle, can also vary widely.
