So basically:

1. He went to Ireland with his vaccinated new wife.
2. While there he got covid, but she didn't. Probably because she was vaccinated.
3. He recovered but ended up with long covid.
4. To fix a completely misdiagnosed issue, his parents took him to a quack chiropractor, who tweaked his neck the wrong way and caused him to have a stroke.

But yeah, the real reason for all his problems is a magical contagious vaccine. I swear this reality is so fucked because of these people.
