https://www.npr.org/sections/health...0796638/covid-vaccine-periods?t=1641693354866 This article claims that COVID vaccines are causing changes in women's menstrual cycles. This has caused a slew of strange comments by women claiming that after vaccination, their period stopped. Overall, this seems uncomfortably similar to the conspiracy theory that COVID vaccines will affect women's reproduction. My questions are: Is this effect on women's reproductive parts exclusive to the COVID vaccine? Will this affect women's fertility and birth rates?
