Mechanism of action

Adacel contains inactivated toxoids of diphtheria and tetanus, acellular pertussis antigens, and inactivated poliovirus particles. When administered, these antigens trigger both humoral and cellular immune responses, leading to the production of protective antibodies and memory immune cells against these four pathogens. This provides active immunization and protection against these infectious diseases.
