I feel like this could happen in two ways:
- People who have had early vaccines are allowed to do things in their own country that others are not
- People from COUNTRIES that haven't had a wide vaccine rollout are going to be discriminated against on the global stage (Oh you're from X country you can't come in)
(I also think we're already seeing "vaccination geopolitics" starting but that's another topic)
I'm not sure about #1, at least not in most western countries, cause they have shown they don't really care about protection.
#2 though, will definitely be another racist covid scare in the near future.
Yeah I thought it wouldn't happen much in the west too, but one of the top news stories in the UK today is about how pubs might only let you in if you've had a vaccine.
