The rare, fully-vaccinated, delta / delta plus breakthrough cases tend to be very mild. Anti-vaxxers are an existential threat to sane people because that's where variants are going to evolve that could defeat current vaccines.

If we're going to "optimize" life for as "little risk as possible," then optimizing for the wrong things is inevitable.
