FDA Pertussis Vaccine Study Shatters Illusion of Vaccine-Induced Immunity

A baboon study conducted by Food and Drug Administration (FDA) researchers revealed that DPT and DTaP vaccines can protect against developing whooping cough symptoms, but neither vaccine prevents infection or the ability to transmit infection. At two, four and six months of age infant baboons were given either acellular (DTaP) or a whole-cell (DPT) pertussis vaccine. The baboons had high antibody levels after getting vaccinated, but when exposed to B. pertussis at seven months old, they colonized B. pertussis and were able to infect other baboons even though they didn't get sick themselves.
NVIC president and cofounder Barbara Loe Fisher said, "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 disease-such as paroxysmal coughing-they do not prevent colonization of B. pertussis bacteria and transmission of the infection to others."
