That's cool and all bro, but the threat is more to them, not you, as all your links/sources explain if you bothered to read them. The probability that they bring you COVID compared to the thousands of other guests is so small as to be imperceptible. You're making the argument that them evaluating their own personal risk in a manner not maximally beneficial to themselves is somehow a threat to you and yours. (I'm especially not sure what them getting Havana Syndrome or Morgellons from being unvaccinated has to do with any of this but you decided it was a top three important point.)
