Patent ID: 8398983

Claim:
An immunogenic composition comprising: (a) a Haemophilis influenza type b (Hib) saccharide conjugate, (b) an N. meningitidis capsular saccharide conjugate derived from a strain selected from the group consisting of serogroups A, B, C, W135 and Y, (c) whole cell pertussis, and (d) hepatitis B surface antigen, wherein the saccharide dose of the Hib saccharide conjugate is less than 5 μg and the saccharide dose of the N. meningitidis capsular saccharide conjugate is less than 5 μg, and wherein the Geometric Mean Concentration (GMC) for whole cell pertussis or hepatitis B achieved with said immunogenic composition is higher than the GMC achieved after immunisation with said immunogenic composition containing a 5 μg saccharide dose of Hib saccharide conjugate and a 5 μg dose of N. meningitidis capsular saccharide conjugate.
