Conditions
Brief summary
This is Phase IV, Open label, Multicenter study. Subject's parents and/or legal guardian will be provided information about the trial. If interested and if eligible, they will then be asked to provide signed informed consent. The initial study visit can occur immediately after signed informed consent has been obtained. Approximately 135 subjects will be enrolled to receive 4 doses of intramuscular MenACWY vaccine at 2, 4, 6 and 12 months of age.
Interventions
Four Intramuscular doses of MenACWY vaccine at 2, 4, 6 and 12 months of age followed by two blood samples at 13 and 24 months of age.
