Bordetella pertussis vaccine. It is highly infectious in unvaccinated people. Acellular pertussiscontaining vaccine is recommended for. In this study we show nonhuman primates vaccinated with aP were protected from severe symptoms but not infection and readily transmitted Bordetella pertussis to contacts.
The DTaP vaccination replaced the previously used DTP shot which protected against the same three diseases but used a whole-cell preparation in the pertussis componentthat is it contained inactivated but complete Bordetella pertussis bacteria. Until the beginning of the 1990s it was used as a part of the DTwP vaccine for the immunization of children. Jules Bordet and Octave Gengou isolated Bordetella pertussis a causative agent for whooping cough in Paris more than 100 years ago which created an excellent opportunity to invent a vaccine.

Although vaccination has been effective Bordetella pertussis is increasingly causing epidemics especially in industrialized countries using acellular vaccines aPs.
They are being replaced by acellular vaccines composed of purified surface antigens mainly fimbriae filamentous haemaglutinin pertactin and pertussis toxin.
