Did you hear vaccinated people with Delta “have just as much virus in their nose so are just as infectious as unvaccinated”?
Turns out vaccinated people have significantly less culturable virus present at the same Ct count
They are LESS INFECTIOUS 💥 https://t.co/OX0Ul0ntWc pic.twitter.com/3vDQSJ6j84

This is not real evidence supporting real policy choices as they are really carried out in the real world.
Instead, this is theoretical bioplausibility spun into a full paper.
