Norwegian scientists have discovered an unusual side effect in COVID-19-vaccinated women who don’t menstruate: atypical vaginal bleeding after injection with the Moderna and Pfizer vaccines.
Researchers studied close to 22,000 women across different reproductive aging stages over about nine months and found that 3.3 percent of postmenopausal, 14.1 percent of perimenopausal, and 13.1 percent of premenopausal women experienced at least one unexpected bleed after receiving the COVID-19 shot, according to the authors of the study published in Science Advances.
