Women have been raising concerns about the shots’ adverse effect on their menstruation ever since the Covid vaccines were initially made accessible more over a year and a half ago.

For instance, Marcie Smith Parenti described distressing instances from her own social circle in an August 2021 piece at The Grayzone that condemned the U.S. medical establishment for failing to research the effects of vaccines on women’s reproductive systems:

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.

Social media users criticized The Grayzone for spreading “dangerous disinformation,” “fearmongering,” and being “anti-vax.” In the meantime, the FDA and CDC’s response to the women’s concerns could be best described as a bureaucratic shrug.
