I agree that frequent testing is a big part of the fight. As far as I know, lateral flow test kits (not the same thing, I know) are still freely available here. There have been rumblings from the government that perhaps we should be paying for them. Bad move. I have a small stash of them in a cupboard. They have been accused of being unreliable. Well I've used them twice now and I regard meself as a fairly rigorous chap when it comes to carefully following orders. They are not especially easy to use, at least for the first couple of times. I suspect that they're quite reliable - when used correctly.

But, and I don't mind saying it again, it's all about getting the world vaccinated. I looked earlier at the state-by-state vaccination rates in the US. I noticed, broad brush, that many of the states below 50% vaccination are in the south/Bible Belt. I'll let you tell me the reasons for that.
