In effect then, the herd immunity (vs waiting for a vaccine stuff) is really not the issue?
It IS solely down to 'the curve' and when you choose lock down, so as not to overwhelm health services?
(That makes sense, obviously, but also doesn't, re the '4 weeks behind Italy' stuff, cos we're clearly not.)
So is it balancing a wider spread, more quickly, against the hope that some immunity, however short-lived, buys that extra time, instead of locking down earlier?
I'm sorry to ask you questions - you must be knackered and you don't need to answer - but I'm way more interested in what you, and our other NHS workers here, feel is right, than the confusing messages coming from the gov.
