Double Covid vaccination has to mean something surely?

It has now got to a ridiculous state where the millions of people who have received double Covid vaccinations are still being treated in exactly the same way as people who have either received one or no jabs or have refused to take them at all. Travelling to an amber country on the government's traffic light system could be so much easier and more practical if an individual with two vaccines showing on his mobile phone NHS App just has to show that and get on the plane. Why is this not happening? The UK government is talking about it but only for later in the summer, like August. So what's the point of the double vaccination if the obvious benefits of having them make no difference whatsoever - apart from keeping them safe from catching the infection of course. The sef-isolation business after returning from an amber country is tedious and over the top if you have had the two vaccines done and dusted. Why is this not being taken into account? Yesterday Malta was put on the green list but immediately Malta said they would only accept British tourists if they have had the double vaccination. Voila! The Maltese government sees the sense in this. Why can't the UK government? The traffic light system is the UK government's system, not the rest of Europe's, so Europe is far more interested in the double vaccination programme. Apart from Spain which just said all UK tourists are welcome without even having to produce a negative test, provided they fill in a special health form and get a Q code to enter the country. Passenger planes going to places like Barcelona have subsequently been pretty full. So the system works. But then they have to come back to UK and stay at home without going anywhere for ten days unless they take an extra Covid test on the fifth day which, if negative, allows them to be given their freedom. But they still have to do a test on the eighth day. So that's three Covid tests: day 2, day 5 and day 8 after returning. That's big money because it has to be done through private clinics. Meanwhile the double vaccination proof sits in the NHS App and no one in officialdom is remotely interested in looking at it. It makes absolutely no sense whatsoever.
