Reply to comment by JurassicCotyledon in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

The article stated that the study did not consider any data related to reduction in transmission.

My comment is that, due to that limitation, it is too simplistic to make such a broad recommendation. A better study is needed.

Sure, I agree. But I’m wondering if you know of any data that suggests an estimated reduction in transmission rates associated with these vaccines.

That’s the real question. Id wager they are stil ongoing, as it’s still too soon to get a broad scope of it, especially with the different variants and weather change.

Agreed. Another big question is the comparable impact of vaccine immunity alone reducing transmission, compared to natural immunity from previous exposure. Nearly everyone has been exposed at this point, vaccinated or not. And we don’t have a very effective means at identifying a control group.
