look at my post a couple above yours. 80%+ is what's been reported80 percent and up, I believe -and don’t quote me - that it was around that for the delta variant
some of these look at omicron alone, others combine it with delta, but given omicron was 90%+ of cases since December, it wouldn't change the picture much. most of the data claiming reduced efficacy against omicron are looking at the risk of infection, not of hospitalization or death. I haven't seen any studies refute the strong protection against serious illness from omicron. I'll post some if I come across them in the coming days.
