I don't have an RCT which establishes this. But I'm not the one who asserted that the Pfizer or Moderna vaccines prevented transmission. You have the burden of proof in this situation. Hence my reference to the astounding amount of certainty in your comment.

I think it is completely clear from the statement that you made that: the vaccines are effective at treating symptoms of covid and that they will reduce the symptomatic infection rates.

However, symptomatic infection rate and infection rate are decidedly not the same and we've know from the beginning that asymptomatic spread occurs substantially with covid.

The only way you establish the effect on transmission is with a large-scale RCT using a well-designed testing protocol. This may be hard but this is the standard.
