Yes, I confess I was surprised to read it would be available for all adults over time (summer 2021?). I thought they were stopping at 50, and younger only if vulnerable. Obviously there are some younger non-vulnerable people who are very badly affected, but I'd have thought the added benefit of protecting them wouldn't be worth the massive extra cost - as per flu vaccinations, they could be privately available to those that wanted it. Especially if there isn't perfect knowledge that it stops infection/ transmission, just that it seems to stop people getting very ill (or symptomatic... though I suppose that in itself will minimise transmission) .
Though if there ARE "immunity passports" or whatever (not keen on that at all) I suppose they'd have to be available. I'm happy to take whatever, whenever they choose to give it to me, if it means things start operating properly again and I can have my fucking pizza and wine even a placebo.
