If you want to hang your hat on the possibility that being symptomatic is not a good proxy for transmission be my guest.
OOF.
It's true. The Pfizer trials collected data on outcomes, including symptomatic infection. They didnt collect data on transmission. The assumption has been you have to be symptomatic to transmit. I suppose it's possible asymptomatic people could transmit.
so what is the point of mandating vaccines?
why is this so hard for you?
it's not hard at all...pre-omicron there was overwhelming evidence that the vaccines reduced symptomatic infections and transmission...post-omicron the evidence is not as overwhelming but generally is consistent with the vaccines continuing to reduce transmission
