- even if they haven't had their period in YEARS, study finds
The Pfizer, Moderna and AstraZeneca Covid vaccines cause unexpected vaginal bleeding in older women and women on birth control, a study has confirmed.
While changes in bleeding and periods in menstruating women post-shot have been known for years, few studies have looked at the impact on women who don't normally menstruate, such as the elderly and those on birth control.
But a new study - that looked at data from more than 20,000 women in this category - found the risk of vaginal bleeding increased two to three times in the four weeks after Covid vaccination compared to before the shot.
In women entering menopause and premenopausal women, the risk was three to five times higher.
