I'm not sure what this means. So you got the vaccine then because you're not afraid of it, right? Or you didn't get the vaccine because you're not afraid of COVID-19?
I am also not afraid really of COVID-19 but I got the vax because I'm also not afraid of that. Mostly I'm afraid I'd get it and then pass it to others where that could have been avoided by me just not being lazy for a second. I don't feel like an odd-man though.
But still, it's a novel, deadly disease which has a significant impact on the respiratory system (and perhaps the vascular system as well). The human body and our immune system are incredibly complex. It's far too reductive to categorize all of these collective experiences as just "hypochondria".
And it's not like post-lyme is a fiction either: https://www.hopkinsmedicine.org/news/newsroom/news-releases/...
