A Randomized, Double-blind, Controlled, Active Comparator, Phase II Study to Assess the Tolerance and Immunogenicity of Conjugate Meningococcal C (MnCC) Vaccine in Infants When Administered in Conjunction With Primary DTP/Hib Vaccination at 2, 3, and 4 Months of Age.
A Randomized, Double-blind, Controlled, Active Comparator, Phase II Study to Assess the Tolerance and Immunogenicity of Conjugate Meningococcal C (MnCC) Vaccine in Infants When Administered in Conjunction With Primary DTP/Hib Vaccination at 2, 3, and 4 Months of Age.
Infant phase: To determine the safety of and production of antibodies by a group C meningococcal conjugate vaccine (MnCC), when given at 2, 3, and 4 months of age with routine vaccines.
Booster phase: To compare the safety of and production of antibodies by MnCC with and without MMR and to compare the antibody response to that produced by a low dose of plain polysaccharide vaccine as a way of investigating immune memory
