Since Covid vaccines first became available more than a year and a half ago, women have been sounding alarms about the shots’ adverse effect on their menstruation.
For example, in an August 2021 article at The Grayzone that criticized the U.S. medical establishment’s failure to study the effects of the vaccines on women’s reproductive systems, Marcie Smith Parenti recounted disturbing experiences from her own circle of friends:
Their symptoms have included hemorrhagic bleeding lasting more than a month; heavy intermittent bleeding for four months; passing golf-ball size clots of blood; and extreme cramping, serious enough to land one friend in the ER.
On social media, the The Grayzone was accused of “fearmongering,” being “anti-vax,” and peddling “dangerous disinformation.” Meanwhile, the response of the FDA and CDC to women’s pleas might be best characterized as a bureaucratic shrug.
In August, NPR said the FDA and all three U.S. vaccine manufacturers claimed “they have not seen evidence that any of the vaccines cause menstrual irregularities.” The American College of Obstetricians and Gynecologists said it was “aware” of the complaints, but urged women to plunge forward with vaccinations anyway without regard to the timing of their cycles.
Now, however, a large-scale study adds substantial new confirmation of what thousands of women have been proclaiming since the jabs started. As NBC News reports:
“An analysis published Friday in the journal Science Advances found that 42% of people with regular menstrual cycles said they bled more heavily than usual after vaccination…14% reported a lighter period.“
The study also found many women who don’t typically menstruate—such as those beyond menopause and those on certain long-term contraceptives—experienced “breakthrough” or unexpected bleeding after receiving Covid vaccines.
