No. Many of the vax for which vpds are no longer around are much more effective than the pertussis vaccine. Pertussis is still around because the vax is so ineffective.
The first CHOP page implies transmission goes unvaxed kid - unvaxed kid - unvaxed kid, and infecting unvaxed infants along the way.
Second CHOP page says adults and teens (most previously vaxed) get pertussis and spread it around.
