The journal Science Advances published a much-needed article on the relationship between COVID-19 vaccination in non-menstruating women. Researchers reported that the risk of unexpected vaginal bleeding after vaccination increased 3 to 5 times in non-menstruating perimenopausal women and 2 to 3 times in postmenopausal women four weeks after COVID-19 vaccination. The researchers in this article noted that the findings were similar to two extensive studies published on the topic from the United States and Sweden. Vaginal bleeding occurred in women whether they were on hormone therapy or not.
The mechanism for the vaginal bleeding and relationship to COVID-19 vaccination in this study is unknown. The issue for patients and their doctors is that vaginal bleeding requires further diagnostics to make sure something more serious is not occurring, such as uterine cancer. Since the uterus is hormonally influenced, it seems reasonable to think there is at least a temporary hormonal disruption from the COVID-19 vaccine in some women.
This medical update is being released to those who sign up for my Health Breakthroughs newsletter. My article is not being released to social media as it is unclear whether healthcare providers are still persecuted for discussing or reporting on COVID-19 vaccines. I plan to continue practicing medicine for many years to come.
