Yep, we locked down (eventually, after hoping we wouldn't have to), found we'd left it too late to stop the virus being prevalent in the population, have now realised the infections and R rate aren't coming down that quickly and in order to stop terminal damage to the economy have now loosened the lock down to the point where the government can say they are doing something but have actually left us largely to our own devices. Some will keep at home if they can, others will flout the guidelines with very little comeback. There's a part of me that thinks the hope was that a vaccine (or at least an effective treatment) would have been found by now.
So yes, herd immunity it is. Let's hope that there aren't too many weaker members of the herd.
