You have to think reasonably to get past the language being used.
People think this vaccine actually stops the spread!
Saying that sentence makes me feel like I'm crazy! A vaccine is supposed to stop the spread, so of course it does, right? They changed the legal definition of a vaccine to allow the treatment to use that name and fool everyone who is not up to date with the new definition.
I'd like to see the serious question asked: does the vaccine stop the spread, and what study proves that.
Yes. I think a large independent double blind study that directly compares vaccinated groups against unvaccinated groups would yield useful data. But as far as I know those studies aren't being done.
They had large double-blind trials where they declined to study this basic factor. They all decided it was not helpful to their product to look at transmissability, yet every time I hear a reference to using these treatments to prevent transmission, no one seems to know this fact.
