They are true. My own daughter was in menopause and hadn’t had a period for over a year. When she got her second shot, periods resumed. I don’t know if they are continuing, but she did have them for several months. She’s a nurse and was forced into having shots as her job required them.
Another relative worked in an ob clinic when they noticed an uptick in still births...late term. So ya, the jab does impact women’s reproductive systems. Others are having difficulty conceiving.
