A new study was published in Science Advances on September 22, 2023 and it reveals another scary side-effect for women who received the mRNA COVID vaccination.
For those wondering, Science Advances is a peer-reviewed multidisciplinary open-access scientific journal established in early 2015 and published by the American Association for the Advancement of Science.
The report stated that after the COVID-19 vaccination rollout, there were reports of “menstrual disturbances” above and beyond the normal for women postmenopausal.
“Such events were not addressed in the preceding clinical vaccine trials. The European Medicines Agency recently decided that the product information of the mRNA vaccines (i.e., Spikevax and Comirnaty) should be updated to include heavy menstrual bleeding as a potential side effect,” the report said.
A study of all female participants “considered considered nonmenstruating. Women who reported having had a hysterectomy were ineligible.” Additionally, women who reported they were still menstruating were ineligible for the study.
The study found a fivefold increase in bleeding.
The study reported:
The Norwegian Institute of Public Health followed several cohorts throughout the pandemic and early performed a systematic data collection of self-reported unexpected vaginal bleeding in nonmenstruating women. Among 7725 postmenopausal women, 7148 perimenopausal women, and 7052 premenopausal women, 3.3, 14.1, and 13.1% experienced unexpected vaginal bleeding during a period of 8 to 9 months, respectively. In postmenopausal women, the risk of unexpected vaginal bleeding (i.e., postmenopausal bleeding) in the 4 weeks after COVID-19 vaccination was increased two- to threefold, compared to a prevaccination period. The corresponding risk of unexpected vaginal bleeding after vaccination was increased three- to fivefold in both nonmenstruating peri- and premenopausal women. In the premenopausal women, Spikevax was associated with at 32% increased risk as compared to Comirnaty.
The report did note that it is the first study of its kind and future studies must be done.
“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.
Unexpected vaginal bleeding in post-, peri-, and premenopausal women generally have different underlying causes. However, our findings of an… pic.twitter.com/2TE2AY80qV
