I believe the UK just ordered millions of antibody tests, that will tell you if you've previously had the virus. If we can confirm that people who previously had it are immune, we should be able to selectively let those back into normal society a lot faster.
Which creates a two-tier society. Those with antibodies get to go about their business, go out to cafes and pubs, get hired for jobs which antibodyless people can't do.
Those who don't have the antibodies are stuck under house arrest, so decide "ahh screw it, I'm going to go and get infected".
It sounds like the politician hopes the tests are "built" in few weeks but the producer has not them yet and I am not sure they will have in "a few weeks" unless he means months
That's my understanding, I may be wrong.
