It'll start with healthcare and roll out throughout all sectors apart from MPs no doubt, who are public facing too but they'll get a pass.
Or maybe the virus mutates because of the vaccine. Hypothetical of course but I'll use anti biotics as an example. Bugs/viruses evolve to survive. They adapt to spread easier and become resistant to cures.

I'd be inclined to believe this could be happening than it mutating in the unvaccinated but who knows. They won't tell us if it's true.

It's the mutations that are the big danger.
