Just for the record - I have great confidence in my PCP. When the vaccine became available last Spring, he advised us to get the shots. So Karen and I both got the set of shots (Pfizer) - with no ill effects. He also advised us this Fall to get the booster shots - so we did that, again with no ill effects.
I'm retired USAF, so keeping shot records current was not a big deal for me - getting shots was required for worldwide mobility status, so it was no big deal getting the COVID shots. I respect the right of each individual to make his own decision.
