Covid vaccinations’ effect on periods and menopause needs more research | Letters

Rebecca May and Jen Fritz on the menstrual problems that they and their friends have had after having coronavirus jabs

I feel that some complexity has been lost in the studies that Viki Male cites in her article about vaccinations affecting menstruation (Does the Covid vaccine really affect your period? Here's what our study found, 27 July). I had two AstraZeneca vaccine doses, in March and September last year. After each one, my period stopped completely for five months.

For some women, it might be a pleasant experience to miss menstruation - unfortunately I, like many other women, have endometriosis and adenomyosis. The result was that my abdomen swelled for a year - from a 36in waist to a 52in one - and I was in constant pain. This has only now started to subside after four normal periods.
