> I am not describing sterilizing immunity, I am saying that the original, and the most common understanding of what a vaccine is is "something that you take that makes you not get sick". The CDC changed the definition of vaccine on Sept 2, 2021 and removed the reference to immunity.

> every news source reachable via Google says the change has nothing to do with COVID or the effectiveness of the COVID vaccine. Does that sound logical to you? The definition went unchanged for years until the CDC came under direct attack for the effectiveness of the COVID vaccine compared to other vaccines. If it's unrelated, wouldn't that make it quite a coincidence?

  I think the person you're responding to is being facetious. Either way, it doesn't matter: the website in question is a public information page, not a medical reference. The CDC updated it because it was incorrect, and the timing of their update makes perfect sense given the public's confusion (and predation around that confusion).
