Governmeet has announced that you can get proof of your vaccination status - a vaccine passport of sorts - via the NHS app digital.nhs.uk/services/nhs-app
However, I downloaded the NHS app and it turns out that to use it, you have to be registered with a GP in England 
Is there some alternative service for us peasants heathens barbarians people who live in Wales / Scotland / NI or are we just being ignored on this front?
I live in Wales and a relative across the border in England is about to go into a care home, so I presume this issue is going to come up. I'm not sure the "I got vaccinated" sticker that I stuck to the back of my driving licence is going to cut it, somehow.
