Shouldn't double-dose vaccined people be allowed to travel?

There was a time when Boris Johnson said everything depended on the vaccination programme and yet here we are with the government due tomorrow to announce its so-called traffic light arrangement for foreign visits and all the signs are that the only countries to be given the green light will be Portugal, Malta, Israel and Greek islands. What's going on? Surely everyone who has received the two doses of vaccine should be allowed to make their own decisions where they go? Caution in a pandemic is obviously common sense but millions of people in the UK have been fully vaccinated and the government of Boris Johnson should have the courage of its convictions and open up travel. If the vaccination programme lies at the heart of the government policy, as it does, then Portugal, Malta, Israel and Greek islands won't hack it. There are plenty of countries which have successful vaccination programmes. Like the US for example where more than 55 per cent of the eligible population have now been jabbed. Why isn't the US going to be on the green list? It makes little sense and it has to be said that delaying foreign travel for those who have been vaccinated is caution gone mad. Economies everywhere are desperate for holidaymakers' spending power. Let the vaccined have the freedom to go where they choose to countries that have effective vaccine programmes.
