Concerns about a probable link between the coronavirus disease 2019 (COVID-19) vaccine and women’s menstrual duration have fueled social media debate, as many women have reported their period alterations after receiving the vaccine.<\/p>\n
A study published in Obstetrics & Gynecology, a US government-funded study, showed on Wednesday, January 5 that there is a slight delay in women\u2019s period for those who are vaccinated with COVID-19 compared to those who were unvaccinated.<\/p>\n
The study was conducted on nearly 4,000 U.S. women from October 2020 to September 2021, with initial COVID-19 vaccine doses and tracked using a birth control app, Natural Cycles.<\/p>\n
The survey serves about 1,500 unvaccinated women and some 2,400 vaccinated participants -the majority with Pfizer (55%), Moderna (35%) and Johnson & Johnson (7%).<\/p>\n
Following their vaccinations, participants found that their period started roughly a day or two later than usual. However, the number of days of menstrual bleeding did not alter following the vaccination.<\/p>\n
For unvaccinated participants, data were collected separately for six consecutive cycles and resulted in a nonsignificant change in their cycle length.<\/p>\n
The findings are “reassuring” as well as validating for those who saw changes, according to lead author Alison Edelman of Oregon Health & Science University, who told AFP the impacts are tiny and likely to be temporary.<\/p>\n
The minor lengthening of the menstrual period isn’t clinically significant. The International Federation of Gynecology and Obstetrics considers any change lasting less than eight days to be normal.<\/p>\n
Period cycles span roughly 28 days on average, but the exact length varies from one woman to the next and over the course of a person’s lifetime. The study stated that it can also vary when a person is under a lot of stress.<\/p>\n
Other potential alterations in menstrual cycles, such as menstrual symptoms, unscheduled bleeding, and changes in the quality and quantity of menstrual blood, are still being questioned.<\/p>\n
