Studies show that covid vaccine temporarily changes menstruation

Unfortunately, the epidemic caused COVID-19 It is responsible for thousands of problems in the lives of people around the world, including the menstrual cycle.. According to studies conducted in the United States, besides the virus itself causing changes, this vaccine may also be responsible for a more intense period of bleeding against the virus in menstruating people.

The online survey was conducted between April and October 2021 and collected data from people aged 18 and over. According to reports, of the approximately 16,000 regular menstruation participants, 42% felt affected after receiving the vaccine.

Anthropologist Kathryn Clancy, in partnership with some of her colleagues, has conducted research to try to understand whether vaccination against covid-19 is responsible for some type of change in the menstrual cycle. The researcher considered the purpose of the study after feeling the changes in her own cycle while receiving the vaccines.

“I’ve had what’s often called a menstrual flood. I had the worst cramps of my life [após a vacinação]Clancy told Science magazine.

post-vaccination cycle

According to people who participated in the study, bleeding increased more than usual after vaccination, including reports of transgender people and other menopausal people. The survey reveals that 66% of 673 menopausal people reported bleeding, and 39% of 280 trans people who took hormones to change their gender.

In any case, survey information can be problematic with regard to quantitative measures, as Clancy seeks more narrative answers about post-vaccination symptoms. That’s why the anthropologist wants to continue research to learn more about menstrual flow before and after vaccines against covid.

Although it is a simpler study and there is no control group, the results may worry some scientists. In total, more than 165,000 people with two vaccines participated in the online survey.
