First, they still haven't released all the trial data. Second, the data the FDA released on their own website for the Pfizer trials proved they didn't even test all of the participants in the trial for COVID, nor did they test all the 'suspected but unverified' cases of COVID.

There simply is no data to prove they ever prevented transmission. The trials were the best place to prove that, and they DIDN'T EVEN BOTHER TO TRY.
