Thanks, Diane. Hence (as we've all heard a thousand times before) the need for multiple defences: vaccines, masks, ventilation and distancing -- none of which is sufficient by itself, but which are highly effective when used together.

It seems disingenuous to claim that any one of these measures should be discarded because it isn't, by itself, enough to eliminate the risk (and risks) of Covid infection.
