yep - OP got COVID.
Despite the theory making no sense OP assigned the consequences of covid to the vaccination he received not due to a sound theory but due to proximity in time and will now make measurably worse choices for decades for lack of communicating with a medical professional.

We are also dealing with a novel (and evolving) virus and an even more novel set of vaccines. We're still learning about both. I find it silly that one could possess hubris about their stance on such a matter.
