Exclusion Criteria:

  • Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the booster dose of study vaccine, or planned use during the study period.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the booster dose.
  • Administration of a vaccine not foreseen by the study protocol within 30 days prior to booster vaccination or planned administration during the active study period.
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product.
  • Previous booster vaccination against tetanus, diphtheria or pertussis since the last dose received in study 263855/004.
  • History of documented diphtheria, tetanus, or pertussis diseases.
  • Any confirmed or suspected immunosuppressive or immunodeficiency condition, based on medical history and physical examination.
