My guess is that we will have to be more pragmatic (I would actually say "adult") about allowing those most not at risk freedom of movement whilst protecting properly those most at risk. The science community also need to firm up on when they will have a vaccine and how effective it is expected to be. As you know the flu vaccine issued every year only ever has partial success.
I couldn’t disagree more. Even if deaths would be limited at the least at risk groups, by having Covid rampant in society which is what would happen, there is only so much you can do to protect the vulnerable, not to mention surely a duty of care towards essential workers. If that means no fans in grounds among other inconveniences then so be it.
