What is acellular pertussis?
Acellular Pertussis Vaccines. Acellular pertussis vaccines contain inactivated pertussis toxin (PT) and may contain one or more other bacterial components (e.g., filamentous hemagglutinin {FHA}, a 69-kilodalton outer-membrane protein — pertactin {Pn}, and fimbriae {Fim} types 2 and 3).
What is acellular pertussis vaccine used for?

In wound prophylaxis for patients =>7 years, it is advisable to use tetanus/diphtheria (Td ) instead of tetanus toxoid alone in order to maintain adequate levels of diphtheria immunity.
