Mechanism of action

The vaccine contains chemically inactivated toxins produced by Clostridium tetani and Corynebacterium diphtheriae. These toxoids are unable to cause disease but retain immunogenicity, triggering B and T cell responses that generate protective antibodies (antitoxins) against the respective bacterial toxins. Upon exposure to the actual pathogens, these pre-formed antibodies neutralize the toxins and prevent disease.
