I could be misunderstanding how this stuff works, but my understanding was that I likely "had" psoriasis before it flared up. You can have it without having the physical symptoms of it. I'm not saying that I didn't have psoriasis, got the vaccine, and then had psoriasis. I'm saying that it sounds like I might have had it the whole time, but with no physical symptoms, and then the vaccine caused those symptoms to flare up. Again, not saying that for sure happened or anything. Just saying it sounds like a possibility. And if I already had psoriasis, maybe the flare up would have happened eventually anyway, even without the vaccine. But there's no way of knowing if that's the case or how long it would have taken. It doesn't matter either way, because here we are. I just thought it was interesting that the two things may be connected, and I hadn't even thought of that up to this point. As for the "expert opinions," cool. As a young, healthy individual, I probably would have taken my chances and been absolutely fine.
