MeningitisMeningococcal Infection

The purpose of this study is to assess the immunogenicity and safety of Menactra® vaccine given as a two-dose series in infants and toddlers. Primary Objectives: To assess the seroprotection rate (percentage of subjects with a serum bactericidal assay using human complement [SBA-HC] titer ≥ 1:8) 28 days after the second of 2 doses of Menactra® administered 3 to 6 months apart. Secondary Objectives: To assess the immune responses to meningococcal antigens (serogroups A, C, Y, and W-135) 28 days following the second vaccination with Menactra® using SBA-HC and SBA-BR titers. To assess the safety profile of Menactra® after each and any vaccination.

Meningococcal MeningitisMeningococcal Infections

The purpose of this study is to evaluate the safety of a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, compared to the safety of a similar, licensed meningococcal A/C/Y/W-135-DT conjugate vaccine. The investigators will also evaluate the production of antibodies to of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine, as a measure of vaccine effectiveness.

Dose-finding and Safety of 2 Intradermal MEN-ACYW135-conjugate Vaccines

Meningococcal Disease

Invasive meningococcal disease is a worldwide problem with serious repercussions for those affected. Vaccination is recognized as the best way to combat it. The cost of vaccination is prohibitive in many low-resource settings at home and abroad. By harnessing the special immunologic properties of the skin, a dose reduction may be achieved by intradermal administration of the vaccine. The cost savings associated with dose reduction will increase availability of the vaccine.

InfectionsMeningococcal

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.
