  • Occurrence of solicited local and general symptoms [ Time Frame: During the 4-day follow-up period after vaccination ] [ Designated as safety issue: Yes ]
  • Occurrence of unsolicited symptoms [ Time Frame: Up to one month after vaccination ] [ Designated as safety issue: Yes ]
  • Occurrence of serious adverse events [ Time Frame: Up to six months after vaccination ] [ Designated as safety issue: Yes ]
  • Occurrence of specific adverse events of rash, new onset of chronic illness(es) and conditions prompting emergency room visits and physician office visits not related to common illnesses [ Time Frame: Up to six months after vaccination ] [ Designated as safety issue: Yes ]

Ages Eligible for Study:   11 Years to 17 Years   (Child)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Written informed assent/consent obtained from the subject/ from the parent or guardian of the subject.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.
  • Previously completed routine childhood vaccinations to the best of the subject's/the subject's parent's/guardian's knowledge.
  • If the subject is female, she must be of non-childbearing potential, or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for two months after vaccination.

Exclusion Criteria:

  • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.

  • Previous vaccination with tetanus toxoid within the last month.
  • History of meningococcal disease.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition (congenital or secondary), including human immunodeficiency virus (HIV) infection, based on medical history and physical examination.
  • A family history of congenital or hereditary immunodeficiency, until the immune competence of the potential vaccine recipient is demonstrated.
  • History of reactions or allergic disease likely to be exacerbated by any component of the vaccine(s).
  • Major congenital defects or serious chronic illness.
  • Acute disease at the time of enrolment.
