Here's some good news that will hopefully set a precedent for other countries:

Sajid Javid, Health Minister: We’ve looked at it properly and whilst we should keep it in reserve as a potential option I’m pleased to say that we will not be going ahead with plans for vaccine passports. I’ve never liked the idea of saying to people you must show your papers or something to do what is just an everyday activity.

I've never liked that idea either - coz it smells like a creeping fascist apartheid state.

It also has the potential to backfire dramatically. If you've only allowed the vaxxed outside to play, but then there's a surge in breakthrough cases, that's not gonna be a great advertisement for the efficacy of your vaccines.
