No need for anyone to feel like a pariah. There will be 2 consequences for them that I can think of, neither of which needs a tattoo on the forehead...
1. Herd immunity (I think) relies on x% being vaccinated so that the amount of virus in the community is lowered, thus protecting the non-jabs.
2. Only an opinion, but I think insurers will use the opportunity to deny or restrict cover; or more importantly, to refuse payment on an exclusion clause, after a claim is made.
2 is only important to travellers really, but that's a lot of bucket-and-spade hols affected. Maybe. Other countries might make demands too, but that's their issue.
