Consider, however, that being exposed to the virus after being vaccinated reduces your risk of death and/or hospitalization by a factor of 10-20x. The assumption that there are “no sterilizing vaccines” is a little questionable too - even against Delta, the FDA approved vaccines are showing 40-50% immunity against infection, i.e. sterilizing immunity.

Zero Covid countries like NZ and Australia that re-open to the world once their populations hit 80% vaccination will have prevented many deaths among their population.
