Curious, sourland. Do you remember what your reaction to chicken pox was when you were a kid? It's purely anecdotal, of course, but when I was a kid I had very little adverse reaction. Itchy bumps to be sure but at the time I thought the whole thing was a great lark. Later, when I got shingles it was an itchy, burny PITA but NOT what other people's agonized shingles reaction seems to be. And, with this Moderna injection, I'm having very little reaction as well.
It may be that some of us are simply less reactive to this or some family of viruses. I know I've done all the running around for my family. I've masked up and gone through antiseptic wipes but I've hardly been what you might call diligent or scrupulous and I haven't been infected yet. Sometimes it surprises me but then I've always given my immune system its proper workout and am more subject to the diseases of an over reactive immune system: asthma, psoriasis, etc.
Again, purely anecdotal but possibly of passing interest.
