Wife and I got the first two pfizer shots early on, and got them early due to being “essential workers”. Didn’t really want them, but at the time the narrative was that you couldn’t spread the virus if you were vaccinated, so I thought I needed it if I wanted to be around my mother who is taking the cancer medication that fucks your immune system. No side effects to name, other than my wife’s previously very irregular menstrual cycle becoming regular.
