Yeah, we can cross the radioactive thing out. But the human guinea pig trial is still ongoing with the other possibilities on your list. We already know the vaccine isn’t working as hypothesized, as it doesn’t stay localized at the injection site. There have only been two autopsies post-vax to my knowledge, and they both found either the MRNA or the spike protein itself was everywhere, in every organ, and has crossed the blood-brain barrier.

Edit: autopsies where this issue was looked at, i’m sure other people have died and had run-of-the-mill cause of death autopsies post-vax, i.e. opiate overdose, murder victims, etc.
