  Purpose

This study has 2 phases, a vaccination phase and a long-term follow-up phase. In the vaccination phase of this study, the new meningococcal vaccine 134612 will be evaluated in children using Mencevax™ ACWY (in children above 2 years) or Meningitec™ (in children below 2 years) as controls. In the long-term follow-up phase of the study, the long-term protection offered by the vaccines will be assessed up to 5 years after vaccination.

Subjects will be randomized in the primary vaccination phase of the study; no new subjects will be enrolled during the long-term follow-up phase of the study.

Primary Outcome Measures:
  • Vaccine response to meningococcal antigens for subjects of 2 years and above [ Time Frame: One month post vaccination ] [ Designated as safety issue: No ]
  • Meningococcal rSBA titres for subjects below two years of age [ Time Frame: Prior to and one month after vaccination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Meningococcal rSBA titres in all evaluable subjects [ Time Frame: Prior to, one month and 1, 2, 3, 4, & 5 years after vaccination. ] [ Designated as safety issue: No ]
  • Anti-meningococcal polysaccharide concentrations in all evaluable subjects [ Time Frame: Prior to, one month and 1, 2, 3, 4, & 5 years after vaccination. ] [ Designated as safety issue: No ]
  • Anti-tetanus toxoid seroprotection and antibody concentrations [ Time Frame: Prior to and one month after vaccination ] [ Designated as safety issue: No ]
  • Meningococcal hSBA titres in subjects below two years of age [ Time Frame: Prior to and one month after vaccination and 1, 2, 3, 4, and 5 years after vaccination ] [ Designated as safety issue: No ]
  • Occurrence of solicited local and general symptoms [ Time Frame: During the 4-day follow-up period after vaccination ] [ Designated as safety issue: No ]
  • Occurrence of unsolicited symptoms [ Time Frame: Up to one month after vaccination ] [ Designated as safety issue: No ]
  • Occurrence of serious adverse events (including meningococcal diseases) [ Time Frame: Up to six months after vaccination ] [ Designated as safety issue: No ]
  • 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 and any events related to lack of vaccine efficacy [ Time Frame: Up to six months after vaccination ] [ Designated as safety issue: No ]
  • Occurrence of serious adverse events related to vaccination and any event related to lack of vaccine efficacy (i.e. meningococcal disease) [ Time Frame: From 6 months up to five years after vaccination ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Group A
All subjects received GSK Biolgicals' meningococcal vaccine 134612.
Biological: meningococcal vaccine 134612
One intramuscular dose.
Active Comparator: Group B
Subjects including and above two years of age received Mencevax™ ACWY, subjects below two years of age received Meningitec™.

Detailed Description:

Subjects will be enrolled in 3 age strata. Subjects including and above two years of age will receive either GSK Biologicals meningococcal vaccine 134612 or Mencevax™ ACWY, subjects below two years of age will receive either GSK Biologicals meningococcal vaccine 134612 or Meningitec™. All subjects will have 7 blood samples taken: prior and one month after vaccination and one, two, three, four and five years after vaccination.
