The unjabbed can't fly in to the US because airlines check proof of vaccination religiously as part of the processing.
Officially, you should similarly be denied entry at land borders.
But since the land border assessment is entirely subjective on whether or not the border agent decides to ask about your status/ask for proof (and they often don't), the likelihood of gaining entry by vehicle is much higher.
My friend just dealt with this over the last few days (from Canada). He couldn't enter through land because of a Biden EO. He could enter through air because that EO doesn't apply to air travel. As far as airline checks, it might depend on the airline and whether they have restrictions, I think he used air canada. But I don't think there's any EO or law as of now that requires airlines to check vax status (as far as I know).
It's actually the opposite.
