Does anyone have good quality info around this with reputable sources ?
This is what Pfizer said 3 days ago:
Can the vaccine prevent severe disease?
The study is designed to detect whether the vaccine can protect against severe Covid-19 disease, Pfizer has said, but data has not yet been made public.
“What we can say is that the vaccine stopped clinic symptomatic infection, but there is uncertainty over asymptomatic infection,” said Hunter. “But we will hopefully learn that as we go forward.”
So at this moment in time you are right. If all pax had the vaccine, at this moment it is uncertain whether that would guarantee they could not transmit the virus to the unprotected.
