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...…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...WW…
