A strategy which has as one of it's primary goals releasing the nation from lockdown isn't a lockdown exit strategy?
The biggest thing that will prevent it's success is our current ability to perform mass antigen testing, and I think whichever way you look at it, that sits on the shoulders of someone withing government. First we were told that the delay in enabling this to be rolled out was because we had to be certain of the tests accuracy and we were trialling several different tests from several companies and only when we knew which was the most effective and its accuracy rate could be guaranteed would we buy the numbers needed. Then we went and bought just under 2 million testing kits that didn't work. We were promised that by the end of this month we would be completing 100,000 antigen tests a day, which is a massive improvement but still only 25% of what Germany has been doing.
You keep stating that 'herd immunity', and I hate that phrase, is the only realistic target.
A vaccine wont be available for at least a year, so you are still proposing we intentionally infect the whole country and let 250,000 innocent people die so that people can get back to work. I'd say no right thinking person would say that, but it's exactly the people that are. The Hitchens, Hannans and Youngs of the world who are either getting crucified by the science and economic community or refusing to speak to them. So they don't get crucified. It is bad thinking, bad science, bad everything. The people in the promoting the idea have no scientific or economic qualification for doing so , and this isn't a left/right argument because an awful lot of the economists that are doing so much to shut those idiots up are right wing thinkers.
IF, and it always gets back to that word, IF we started to develop or acquire the sofware to enable anonymous tracking now, manage, and God knows how we will, to be performing 100,000 tests a day by the end of April we could be out and about in 3 weeks with the minimum risk to the public and the least impact on the economy. over well over the 60% of the populaton ha a phone. Once you have the tracking sofware on it, and have the ability to find out whose got CV-19, isolate them, quickly, inform everyone they've been anywhere near since they were infectious so that they can get tested too and isolate them, and you go a long way to solving the immediate problem.
Without sacrificing 250,000 lives so you can get a bit of sunshine.
