Everyone wants to get on with their lives, but at what cost? thats what it comes down to. We will either pay in economic damage, lost lives or (looking likely) both.
Again, I dont understand the rush to throw so many lives under the bus with so little care, its bewildering.
Those people, our vulnerable, can be sacrificed at anytime, but they can only be sacrificed once.
Lets try something else for a few months first, and see how it works.
If nothing else works out, we can always fall back to the "let everyone in society who has an underlying condition of some kind die" plan afterwards.
