I wonder if H1N1 cross-reacts? That is, if you get T-cell recognition from it?

Because I had SOMETHING, which I assumed was either H1N1 OR Covid, first week of January 2020. It was NASTY. By the time I could get antibody tests I was seronegative, but that's not surprising.

Since I've been repeatedly exposed -- enough times that I've lost count -- and have not gotten it. So either I had it (and it wasn't H1N1), I'm the luckiest SOB alive (as I didn't even get a LOW symptom or asymptomatic case), my prophylaxis protocol works (possible; non-pharmaceutical, supplement based and easily OTC available) or I had some OTHER virus that cross-reacts sufficiently to prevent an infection sufficiently bad to build a specific antigen response.

I ain't buying the "luckiest SOB alive" explanation.
