"The USA: Nothing has changed since my visit to the USA in August where proof of a vaccine passport is still required for entry. It seems to be devolved to the airlines to enforce this as you are not allowed to check in until you have completed and uploaded an attestation form (‘I do not have Covid’ – tick!) and a PDF of your vaccine passport. Nobody asks for any proof at U.S. immigration. Once again, I say: it really is time that British Airways, and we British generally, stopped kowtowing to other countries. It is worth noting that any two doses of an approved vaccine will suffice and taken at any time which means that my non-boosted AstraZeneca vaccines of early 2021 are recognised. These shots did not protect me at the time and even if they had any benefit at that point they will be of absolutely no benefit now. My impression is that this is an exercise in box-ticking to demonstrate the traveller’s compliance with the Covid regime. Apart from hand sanitisers – these have always been quite prominent in germophobic America – there was absolutely no other indication of the Covid regime. Some people continue to wear face masks and, as I was at a nursing conference, some masks were in evidence. There was no compulsion to wear face masks and it was refreshing to have several conversations with unmasked colleagues, mainly of a Republican persuasion, about how ridiculous face masks were and what harm lockdowns had done to our economies."
