I am guessing restrictions will be put in place, and so they should be.
At present, teenagers need ID to prove they are old enough to purchase items or to be allowed into establishments. There's never been an outrage about that, so why is proving you've had a vaccination to travel or to go to an enclosed space like a pub or cinema any different?
A cruise company recently said that they are going to ban people who haven't had their full vaccination. The people commenting are mainly in uproar. I bet they are the same people who would complain if their ship was quarantined on the seas for weeks on end.
Companies are not charities. They don't run on air either. If people do not feel safe, they won't go on board and the company collapses. Same with pubs etc. They don't want to be closed down again, so are safeguarding the customers, staff and profits.
You wouldn't take your child to kindergarten if you knew the teacher is an ex paedophile, so why go to an enclosed space where there's no social distancing, no masks worn, and with people who think it's all a joke and don't give a shit.
If a company doesn't want to employ you because you won't take a vaccination, or a company won't allow you into their premises etc. Then so be it.
