"Acellular pertussis vaccines protect against disease but fail to prevent infection and transmission in a nonhuman primate model"
The study concluded that infant baboons given Sanofi DTaP (Daptacel) vaccine at two, four, and six months of age were protected against developing outward clinical symptoms of pertussis after being exposed to B. pertussis at seven months of age, but they were still able colonize and transmit B. pertussis to other baboons.

or as lay person but respected researcher Barbara Loe Fisher has stated with regards to the above study:
(Fisher has served as one of the Fed government's vaccine panel board members, which is not easy for a lay person to do,unless they are accepted by a large community)
"In my opinion, this study in infant baboons suggests that pertussis vaccine-acquired immunity has been an illusion. Although the vaccines may protect against severe B. pertussis clinical symptoms of the diseasesuch as paroxysmal coughingthey do not prevent colonization of B. pertussis bacteria and transmission of the infection to others."
Fisher migh be a little bit hard to folow, but what she is saying is that after a baboon has been infected with the WC anti bodies, the B. pertussis bacteria is then found in the lining of the throat. In a human being, the throat would perhaps be irritated and perhaps sore, but most significantly this person can then infect others with whooping cough.
