Formulations
Pertussis vaccine is a component of the DPT vaccine.
Older versions of pertussis vaccine involved inactivated cells. Newer versions are acellular, and are less likely to provoke a febrile state.
In 2005, two new vaccine products were licensed for use in adolescents and adults that combine the tetanus and diphtheria toxoids with acellular pertussis (Tdap) vaccine. These vaccines are the first acellular pertussis-containing vaccines that make it possible to vaccinate adolescents and adults against pertussis.
