The largest study published by the journal Science Advances to learn about the relationship of menstruation with coronavirus vaccine has been published to date. People with 39,129 months participate, Katherine M. N. Lee and Eleanor J. In the research designed by Junkin. It is concluded that while 44% of participants on a regular course did not experience changes after vaccination, 42% experienced more bleeding after the dose.

In addition, the study reveals that some people who usually do not have menstruation have had intermenstrual bleeding. These include 71 per cent of people taking contraceptives, 39 per cent of those taking hormonal therapy, and 61 per cent of those who have been through menopause. The researchers point out that the results found do not produce serious alterations, but consider it necessary to take it into account in order to “build trust in medicine”.

All participants in the study received the full dose at least 14 days before interrogation and did not reach the coronavirus.
