Your first paragraph is condescending and unnecessary.
Can you cite any sources that confirm that "governments, researchers and medical professionals worldwide claimed they did test effectiveness against transmission"? I haven't seen any, and a cursory Google search reveals articles like this [0] which confirm my memory that this was never claimed by the vaccine researchers. Independent research after the vaccines were released did find they reduced transmission significantly (for the early variants).
This reference to the Pfizer "admission" seems way more like a gotcha tactic. Pfizer never made the claim, nor was it necessary to show the vaccine was safe and served its primary objective.

Edit: Oops, forgot to cite my source :P
