I agree with the problems with attempting to build herd immunity in the context of this outbreak that you have listed (I have previously expounded on them) but establishing herd immunity without vaccination usually *does* take years in a ‘normal’, large, isolated population with no pathogen mutation. I think
@BobKowalski was making the point that it was never going to be a viable strategy in of itself, even leaving out the very real issues you, I, and many more learned experts have outlined.
Whether the government intends or intended for it to be the main plank in their plan is up for debate — they seem to be a bit inconsistent with their messaging regarding that since the initial day of response escalation when it was referenced.
It may have just been bad communication which lead to misunderstanding (as it’s not just us on here that thought establishing herd immunity was a main element of the response based on their words) or it could be it was the greater thrust but they are now walking it back due to the backlash.
We’ll probably never *really* know.
But it is safe to say if it was ever the primary element of the response, the general scientific consensus (excluding apparently a few groups advising the government) is that it is a very risky and problematic plan.
