Covid vaccines may increase risk of ‘unexpected vaginal bleeding’, study warns

preview

Covid vaccinations may increase the risk of “unexpected vaginal bleeding” several-fold in nonmenstruating women, a study of nearly 22,000 subjects has warned.Nonmenstruating women include those who are postmenopausal, as well as those on birth control pills that inhibit ovulation and menstruation.The study did not explore the potential mechanisms by which the vaccines might be causing unexpected bleeding.However, the researchers have speculated that it has to do with the SARS-Cov-2 spike proteins, which the mRNA vaccines in question induce the body to produce so the immune system can make antibodies against the real virus.It is possible, they said, that the spike proteins cause an immune response in the endometrium, the inner lining of the uterus, or alternatively from the expression of the ACE2 receptors (to which the spike proteins bind) in the same tissues.

For postmenopausal women, the increase was smaller, at just two–three times.Further studies, the team cautioned, will be needed to confirm the findings. Unexpected vaginal bleeding after menopause can be a sign of serious medical issues — such as endometrial cancer as well as precancerous lesions.Professor Kate Clancy is a biological anthropologist at the University of Illinois Urbana–Champaign who was not involved in the present study, but has undertaken research which has produced similar results.She told Nature News: “Postmenopausal bleeding is often very concerning and a possible sign of cancer.“Knowing a patient’s vaccination status could put their bleeding incidence into context.”She added that vaginal bleeding patterns need to be monitored in the clinical trials of vaccines in the future.The full findings of Blix et al.’s study were published in the journal Science Advances.Follow our social media accounts on https://www.facebook.com/ExpressUSNews and @ExpressUSNews Covid-19 Coronavirus Vaccine SEARCHCONNECT WITH US Copyright ©2023 Express Newspapers.
