Vaccinated people do not spread the virus nearly as effectively as unvaccinated people.

And you did not address the threat to our hospital system, which has been the number one concern for a year and a half. Surgeries are already being halted in multiple states... again. You might view it differently if it was your hospital that postponed your surgery because unvaccinated people had filled all their beds because of a preventable illness.

There was a study upthread (from the Lancet?) that literally pointed out that there are the same level of virus load on nasal pathways for vaxxed and unvaxxed. I believe the study was linked by user timr

This was the underlying logic for the cdc to require masks once again

Yeah, we need a lot more data points than one tiny study. Almost all data to date shows vaccinated people do not spread the virus as effectively as unvaccinated people, and that vaccinated people are far more likely to have asymptomatic (not pre-symptomatic) infections, and most data points to those types of infections having a very low rate of transmission. One chunk of leaked data does not negate all previous research.

Here is a link to the actual study. I would take a look at the limitations discussed in the Discussion section.
