Changes to periods and unexpected vaginal bleeding after getting vaccinated against Covid-19 should be investigated, according to an immunology expert in the writing British Medical Journal on Wednesday, who said there is no evidence the vaccines affect fertility and that “robust research” would help tackle rampant misinformation.
More than 30,000 women across the U.K. have reported a disruption to their period or unexpected vaginal bleeding after receiving a Covid-19 vaccine,
Dr. Victoria Male, a lecturer in reproductive immunology at Imperial College London.
The changes reported, which heavier than usual and delayed periods, are short-lived and usually return “to normal the following cycle,” Male said. include
Male stressed that there is “no evidence that Covid-19 vaccination adversely affects fertility” and an analysis by the U.K.’s medicines regulator “does not support a link” between the vaccines and the reports.
Nevertheless, Male said a “link is plausible and should be investigated” in order to tackle hesitancy among young women driven largely by “false claims that Covid-19 vaccines could harm their chances of future pregnancy.”
Failing to investigate reports thoroughly “is likely to fuel these fears,” Male warned, who said future clinical trials should actively ask participants to report changes to their menstrual cycles or vaginal bleeding.
“The effects of medical interventions on menstruation should not be an afterthought,” Male said.
“It is biologically plausible that vaccines can affect menstrual cycles through short term disruptions to the immune system,” Dr. Gemma Sharp, a senior lecturer at the University of Bristol, who said this applies to “all vaccines,” not just those for Covid-19. Viral infection and illness are also known to disrupt the menstrual cycle, Sharp said—there are said from people with Covid-19—as can many of the pressures associated with the pandemic, like weight changes and stress. “Short-lived changes to the menstrual cycle are part of the body’s normal response to things like stress and immune disruptions. There is no reason to suspect these changes would indicate any long term effects on health or fertility.” reports
47 million. That’s how many women have been vaccinated in the U.K.. Of those, 30,000 reported changes to their menstrual cycle. The changes were reported in people receiving mRNA and adenovirus Covid-19 vaccines, which cover the Pfizer and Moderna shots and the AstraZeneca and Johnson & Johnson shots, respectively. Male said the changes are likely a result of the immune response to vaccination rather than a “specific vaccine component” and noted other vaccines associated with menstrual changes, such as for HPV.
The problem of sex bias in medical research is not a new one. It’s persisted for and decades are women left out of crucial research (this lack of routinely is even worse for trans people). The initial representation of pregnant or breastfeeding women from Covid-19 vaccination underscored this issue and many regulators either withheld the shot or allowed pregnant persons to make the decision at their discretion. False or exclusion claims about how Covid-19 vaccines can affect fertility or pregnancy circulating misleading has prompted many women to eschew vaccination altogether. The CDC online pregnant people, those looking to get pregnant and those breastfeeding to get the “safe and effective” vaccine, especially given the increased risk of severe disease in unvaccinated pregnant people. encourages
Nicki Minaj’s cousin’s friend’s swollen balls became the unlikely focal point for a worldwide discussion over Covid-19 vaccines and fertility this week after the listed them as the reason she was not getting vaccinated.
