COVID-19 Vaccines Can Make Periods Longer, Study Says (TIME)

The latest study documents how COVID-19 vaccines can increase the length of menstrual cycles—though the change is minimal and temporary.

until fall of 2021, so the scientists are also investigating whether additional vaccine doses affect cycles in the same way. [effect that the vaccines have on menstruation.](https://time.com/6198573/covid-19-vaccines-periods-mentrual-cycles/) It included nearly 20,000 vaccinated and nearly 5,000 unvaccinated people around the world. Temporary inflammatory reactions after immunization, similar to those generated after getting natural infections, could affect processes like ovulation, and the extent of the effect could depend on when during the cycle people get vaccinated. “Hopefully this will create a foundation for information about menstrual cycles and future vaccines as well,” she says. They are also exploring how getting infected with COVID-19 might affect periods, since infections of any kind are known to affect menstruation. Edelman and her team found that the effect on menstrual cycle length was similar with all of the COVID-19 vaccines. The latest data add to the existing data gathered from the U.S. “Now we have information to know that the vaccine does change the menstrual cycle, at least on a population level. That means that the newer mRNA-based shots don’t seem to be associated with any menstrual changes than the other vaccines, which should allay concerns about the novel technology. Edelman and her team are also continuing to mine the data to answer other questions about how the COVID-19 vaccines might affect menstruation, including whether vaccination affects menses itself. The team also found that this change tended to only last for one cycle after vaccination, resolving by the next period. Side effects from vaccines are not unusual, and in fact are expected.

“We want to emphasize that the menstrual cycle changes at a population level are small and typically resolve in the cycle after vaccination. On average, vaccinated people experienced an increase of less than one day in each cycle in which they were vaccinated: a 0.71 day increase after the first dose and a 0.56 day increase after the second dose. Additionally, changes in cycle length appeared to be similar across the different vaccine types, offering reassurance to those with concerns about newer vaccine technology, Edelman said. Although researchers believe these changes are likely due to temporary, vaccine-related activation of immune response, more research is needed to fully understand the biological mechanism. However, clinical trials of vaccines do not collect outcomes related to menstrual cycles, leaving a significant gap in knowledge around these issues, prompting Edelman and team to look more closely at what was being reported by the public. cohort: Individuals who received two doses of a COVID-19 vaccine in a single menstrual cycle saw an average increase in cycle length of 3.7 days compared with the unvaccinated group. “Menstruation is woefully understudied, which is troubling considering it is a key indicator of fertility and overall health,” said Edelman, the study’s lead investigator and professor of obstetrics and gynecology and division director of Complex Family Planning in the OHSU School of Medicine. Additionally, the study was not designed to determine why these changes might happen. Additionally, researchers were able to look at menstrual cycles after receiving the vaccine to see how long it might take to resolve any changes. However, researchers say there needs to be further investigation into other changes to menstrual cycles, such as unexpected vaginal bleeding, menstrual flow and pain. Some individuals experience a slightly longer cycle length with the COVID-19 vaccine, and, for most, it goes back to normal quickly.” Vaccinated or not, individuals experienced changes in their cycle length, but a larger proportion of vaccinated individuals had an increase in cycle length of more than eight days (13.5%), compared with those who were unvaccinated (5%).

Nearly 15,000 people in the study were vaccinated and just under 4,700 were not.

Covid Vaccines Temporarily Affect Periods, New Study Shows (The New York Times)

Experts say there is no indication that vaccines affect fertility. Most people's periods go back to normal within one cycle.

[new vaccines](https://www.nytimes.com/2022/08/31/well/covid-booster-shots-variants.html?action=click&pgtype=Article&state=default&module=styln-coronavirus&variant=show®ion=MAIN_CONTENT_1&block=storyline_top_links_recirc)are one of the last remaining weapons in America’s arsenal against the coronavirus. Experiencing any side effect after getting vaccinated — whether a change in menstruation or a headache or fever — is not an indication of how well your vaccine is working. As a result, the number of days you bleed, the length of your cycle and the heaviness of your flow can fluctuate. “Such changes are unlikely to be the result of vaccination.” Some people are simply more sensitive to immune-system or hormonal changes in the body, Dr. There is most likely some cross-talk between the immune system and other parts of the body that help protect against outside pathogens, including the reproductive system. The study did not include data from people who were on birth control or people who already had irregular cycles before getting vaccinated. Individuals who received both shots in the same menstrual cycle experienced a bigger change: Their periods were, on average, almost four days late. The hormones that regulate your monthly cycle can be affected by a variety of factors, including stress, weight loss or weight gain, calorie restriction and intense exercise. Alison Edelman, a professor of obstetrics and gynecology at Oregon Health & Science University School of Medicine and the paper’s lead author. It includes data from nearly 20,000 people around the world — 14,936 of whom were vaccinated and 4,686 who were not. [BMJ Medicine](https://bmjmedicine.bmj.com/content/1/1/e000297), researchers reported that, on average, vaccinated people experienced about a one-day delay in their periods compared with those who did not get vaccinated.
