I don't think any vaccine study had odds of transmission as one of the end points. How do you even design such a study?

  It's not complicated- by reducing the odds of contracting covid, the odds of transmission are reduced.

    Vaccine efficacy is measured against symptomatic COVID‑19. It's quite possible that asymptomatic carriers transmit more (e.g., because they do not self isolate, or because they shed the virus for a longer period of time). You may be right, I'm just saying that it does not follow from the results of vaccine clinical trials.

    Please correct me if I'm wrong, but I was under the impression that covid spreads predominantly from the nasal cavity, where vaccines would have little effect.
