I don't disagree with you, but I think the more root cause thing is - people should be more humble in listening to the advice and guidance of epidemiologists, and indeed other experts and specialists.

We as a society tacitly "outsource" the task of becoming an expert to a bunch of mostly smart and well-meaning folks, in all sorts of areas, because we cannot all know "everything" - and for some reason on vaccines and epidemiology great swathes of the population, including senior leaders politically, now choose to ignore their clear guidance on how best to act.
