There was some CDC data published recently on breakthrough infections in the US (I don't have a better site--saw it somewhere on Apple New+). It worked out to 4 COVID hospitalizations or deaths per 100k.

For comparison, that's about twice the US death rate due to flu in 2019, and about 1/40th the US death rate due to COVID before vaccinations were available (and before the delta variant was in the US). That's about 10x better than death rate pre-vaccination in the state that had the lowest death rate (Hawaii).

Aren't you comparing Delta numbers for vaccine and pre-Delta numbers for no-vaccine then? So really you'd expect the difference to be even greater than that.
