Eh, I don't think we can say that with certainty. We know that vaccination is driving down cases. It really feels borderline whether it's enough for herd immunity.

(Rich) countries are already rolling out third doses, at least for the most vulnerable. Longer term, we'll have revised vaccines, even more effective against Delta.

Maybe you're right, we can't avoid catching COVID long term. But if that's the case, hopefully its severity is (even further) attenuated by then, due to further vaccination.

Or wear a P100 elastomeric respirator when going in places.
