Hi All. I just completed my 4th year on Tamoxifen. About a couple of years ago I finally stopped getting the horrendous hot flashes and night sweats. I received the Pfizer COVID-19 Vaccine and not long after, started getting hot flashes again. When I had my onco appt this week with bloodwork, I asked to have my estrogen checked. The results came back and my estradiol level went from <11.8 about 1.5 years ago to 610.4. Has anyone else had a similar situation after the vaccine?

I have heard of younger women having strange periods the month of the vaccine. I actually got covid and had very different cycles for two months, like high estrogen. But it seems to be a temporary response to the virus or vaccine

I haven't been on this site for quite sometime but returned to see if I could get information on the Covid vaccine responses with people on Tamoxifen. I have been on Tamoxifen for 8 years and am doing very well on it. I am concerned how the vaccine will affect the Tamoxifen doing its job. Thank you for your input!

I take Letrozole, not Tamoxifen, but after the vaccine, I noticed that for a good month at least, all of my Letrozole side effects really ramped up; body and joint aches, sweats, hot flashes, mood swings - all of it.

I also came here to check if anyone was having irregularities with cycles after covid vaccine. My periods stopped during chemo almost 3 years ago. I had 2 occasions of break through bleeding that was very heavy and D&C for thickened uterine lining which came back clear. I have been on Tamoxifen for 2.5 years. It has been 6 weeks since my second dose of Pfizer vaccine and I have had days of cramping followed by heavy bleeding again. I was previously thought to be in menopause even though I am 41 because I had not had regular periods since chemo and only the 2 breakthrough heavy bleeds. I am interested to know if anyone else considered menopausal has had a breakthrough bleed since having their last vaccine.
