Large numbers of women across the world have reported changes in their menstrual cycles after taking the Covid vaccines, including heavier, earlier and more painful periods, as well as unexpected bleeding or spotting among women on long-acting contraception and even those who are postmenopausal and hadn't had a period in years or even decades. The last item, that women who are post-menopausal suddenly having a period, is very odd and should have immediately aroused scientific curiosity. But until recently, when the numbers got too high to ignore, the establishment did just that, bushed the matter off. However, in August 2021, the U.S. National Institutes of Health awarded $1.67 million in grants to five institutions to study links between Covid-19 vaccines and menstrual changes. Thus, the issue is scientifically open at present, but the fanatic quest to jab all women continues. What if the jabs do affect fertility, in an I am Legend type of situation?
