I think I've had 4 now, DW has had 5 and they're recommending another (which she has serious doubts about). Despite all the boosters, she's had COVID twice, yet I haven't had it once. Coupled with that in our close circle of friends there's been 3 that have had serious reactions to the virus. Contrast that with the flu vaccine (which I've taken every year), and I don't recall any reactions to it. The first time DW had it, they gave her Paxlovid, she only had minor symptoms for the 3 days, and was fine. The second time they didn't giver her anything, let her ride it out. She felt rough for week, but came through fine (this is a senior with a compromised immune system). Even the 2nd time was not as bad as some of the flu we've had over the years. The flip side is that we lost quite a few members of our community because of COVID, but over the years there's been a lot of death due to flu. We just have more questions than answers on the COVID vaccine.
