Persistence of Antibodies and Kinetics of B Cell Response in Healthy Children After Vaccination With MCC Vaccine
A Phase IV, Single Centre, Open-label Study to Investigate the Kinetics of the B Cell Response to the C Saccharide Component of Chiron's Meningococcal C Conjugate Vaccine Administered to Healthy Children at Least 12 Months of Age After Priming With a Commercially Available Men ACWY Conjugate Vaccine at 2, 3 and 4 Months of Age

Outcome Measures
Primary Outcomes (1)
Persistence of memory B cells in the blood at least one year after primary immunisation with MenC Vaccine at 2, 3 and 4 months of age, as determined by meningococcal C specific B-cell ELISPot assay or limiting dilution
Secondary Outcomes (2)
Immune Response measured 4 weeks after the booster immunisation.
establish at which day CRM -197 specific B cells are detectable in the blood after booster immunisation, as determined by meningococcal C specific B-cell ELISpot assay or limiting dilution.
