>None of the vaccines prevent transmission - they were never even tested for that.
The popular narrative being told to people from all sources was that vaccines were to prevent transmission which was quietly toned down when it turned out not to be true and then people now say things like "we never said that" when nobody mentioned it at all in the beginning that vaccines quite possibly weren't going to prevent disease or transmission.
People just move goal posts, fail to outline risks that don't align with their advice before those risks are undeniable, and generally always pretend they were right all along.
