The article I posted has a quote and video of the director of the CDC explicitly saying in March of last year that vaccinated people "do not carry the virus" and were 90% protected __against infection__.

That's a direct quote from the head of the CDC, it does not get more official or more of a primary source than that IMHO.

It actually does get more official than a director's spoken words, but moot point. You are writing as if in the year since that largely pre-Delta point in time that the CDC's official guidance was that you won't carry the virus and are protected from infection — and it was never updated.
