Thousands of women who do not menstruate reported experiencing “unexpected vaginal bleeding” after receiving the mRNA COVID-19 vaccine, according to a recent study published in the ScienceAdvances journal.
The study analyzed more than 21,000 responses from postmenopausal, perimenopausal, and non-menstruating premenopausal women, including those taking hormonal contraceptives.
The researchers found that 252 postmenopausal women, 1,008 perimenopausal women, and 924 premenopausal women reported experiencing “unexpected vaginal bleeding,” with half stating the adverse reaction occurred within four weeks of either the first or second COVID vaccination.
Premenopausal and perimenopausal women were most likely to report bleeding within the first month after vaccination. Their risk of bleeding was between “three to five times as high” as before vaccines existed. The risk for postmenopausal women increase up to threefold.
“Our findings indicate that the COVID-19 vaccines, or the host response to them, can lead to vaginal bleeding in a wide range of women,” the study authors concluded.
Kristine Blix, the study’s lead researcher, stated, “The most important contribution of this and other documentation will be that female bleeding patterns are included as end points, or monitored, in clinical trials of new vaccines — and perhaps even drug trials.”
A study published earlier this year found the jabs carried an increased risk of menstrual disturbances of up to 41 percent.
