Patent ID: 8003112

Claim:
An immunogenic composition comprising isolated capsular polysaccharide from serogroup C Neisseria meningitidis , wherein the capsular polysaccharide is conjugated to purified pneumococcal surface antigen A (PsaA), the PsaA being 309 amino acid residues in length, wherein the immunogenic composition generates a murine serum IgG response to both the serogroup C Neisseria meningitidis and the PsaA when administered to mice in an immunogenically effective amount, the murine serum IgG response generated to the serogroup C Neisseria meningitidis and the PsaA being greater than murine serum IgG immune response generated by each of the serogroup C Neisseria meningitidis and the PsaA in a non-conjugated form.
