What could it be often has the connotation that there is more than one possibility. Your rather snarky response belies that possibility. Do you agree to the following:
1. We don’t know if he was vaccinated to a certainty.
2. Even were he, there are other conditions which may cause what is occurring.
3. Btw. What is he in the hospital for? The last thread on this issue wasn’t quite sure despite the answer being directly in the article.
It’s still ‘unknown.’
The red flag is the line “doctors are running tests to figure out what happened”. He’s been there three weeks and they’re still running tests? If the cause is that mysterious, it has unforuntately become a kind of de-facto hint that this may well be the vaxx, since it’s the “cause that can not be named”.
"Jamie Foxx was fully vaccinated by July 2021, as he joined action-thriller film God is a Bullet, which required its cast to be fully vaxxed. Foxx also required attendees to show proof of full vaccination while touring his book Act Like You Got Some Sense."
