We don't all agree on this. Getting a diagnosis of pertussis is influenced by a lot of factors, one of which seems to be whether one has been vaccinated. It does look like vaccinated people have milder symptoms--but it's not clear that they actually don't get pertussis, so it's plausible that they still spread it just as much.
The AAP's journal had a really helpful (to me anyway) article on pertussis--the jist of it was that even doctors expecting to see pertussis had a very, very difficult time distinguishing coughs caused by pertussis from coughs due to other reasons--and since most doctors in this US, until this past year, haven't considered pertussis much, well, it really puts the officially reported CDC numbers in question.

There have been a lot of thoughtful, well-researched threads on this board on the topic of pertussis exploring what we know and what we don't. It's not as simple as "unvaccinated kids/adults are spreading all this illness putting everyone else at risk."
