Steve What I think about that is that the government should not be implementing a vaccine passport scheme, or whatever else you want to call it. Let individual institutions make their own rules. If a shop or an event won't let me in without proof of vaccination, I'd defend that to the hilt.

In the absence of a Government backed passport scheme, what would count as 'proof of vaccination'?
You seem to be confusing the Government providing vaccine passports, which can be used in any situation where the business owner requires them, with Government insistence that all businesses (or certain businesses) must require passports.
