What is the study measuring?

Primary Outcome Measures

Outcome Measure
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 Outcome Measures

Outcome Measure
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.
