How confident are we that being vaccinated for COVID reduces the likelihood that you will transmit COVID to another especially given that vaccination will change your behavior, e.g. if you don’t even notice you have symptoms you don’t stay home in bed when you are infected? This paper is likely relevant: https://www.medrxiv.org/content/10.1101/2021.07.31.21261387v4
This study of actual transmission seems to indicate a substantial reduction in transmission from vaccinated people. But that benefit also seems to fade. I don’t know if the fading is real or how much is from confounding effects (like more and more “unvaccinated” having immunity from prior infection). Someone with more experience in these types of studies than I could dig into that.
