This open label randomised controlled study will evaluate the induction of immunity following varying schedules of vaccination with glyco-conjugate Neisseria meningitidis serogroup C (MenC) vaccines in infancy. 498 infants will be enrolled in this multi-centre trial. Participants will receive either 0, 1, or 2 priming doses of a MenC-CRM197 conjugate vaccine or 1 priming dose of a MenC-TT conjugate vaccine in the first year of life, with all groups receiving a dose of a combination Hib-MenC-TT vaccine at 12 months, as well as all other concurrent routine vaccinations. All groups will also be further divided into 2 groups to receive their routine vaccines in either consistent or alternating limbs to assess the immune response to the concurrent infant routine immunisations administered in consistent versus alternating limbs. Immune responses will be assessed at 5, 12, 12months +6 days, 13 and 24 months of age.
