If you are concerned about COVID booster, call your pharmacist. These guys have a handle on drug interactions and contraindications. I have had boosters regularly. I usually feel crappy for 3-5 days after the shot so I am only getting it once a year now. I get yearly flu.

Just before she retired, my PCP said she would ask elderly patients if they wanted a COVID booster, but she was no longer actively pushing it because a) the virus is less likely to cause fatalities now and b) she was tired of hearing patients argue with her by repeating misinformation they heard. "They act like I'm trying to kill them." Sad to lose her. Hope the new one is as good.
