Pedantics, really. In colloquial terms, it makes sense to describe a vaccine as doing exactly that. Not everyone has a grasp on the statistics involves; a huge number of people learned about R0 for the first time because of covid. People were arguing over whether you should wash your hands and wear a mask like it was the dawn of germ theory; I forgive the media for not going into hour long lectures about viral replication in the body and the expected statistical significance of vaccination...
(And I hate to defend the MSM...)
I mean, yeah, of course they are. With that said, they would be absolutely stupid to do so explicitly. If they actually find evidence during discovery, that just means management is dumb as rocks. So... They might.
