You can go ahead and read the trials yourself. They very much found that the vaccines were excellent at preventing Covid-19 entirely (they did not measure if they also prevented SARS-CoV-2 asymptomatic infection).

It just turns out that they had far too little data and that in real-world conditions they weren't anywhere near the 90+% claimed effectiveness.

Even so, the latest population-level research still suggests that the vaccines were 50-60% effective at preventing Covid-19 entirely, at least for some months.

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.
