MULTIVALENT PNEUMOCOCCAL POLYSACCHARIDE-PROTEIN CONJUGATE COMPOSITIONS AND METHODS OF USING THE SAME

Abstract:

Provided are multivalent pneumococcal conjugate compositions comprising 22-27 different pneumococcal capsular polysaccharide-protein conjugates, wherein each pneumococcal capsular polysaccharide-protein conjugate comprises a protein carrier conjugated to a capsular polysaccharide from a different serotype of Streptococcus pneumoniae, wherein the Streptococcus pneumoniae CA serotypes are selected from 1, 3, 4, 5, 6A, 6B, 7F, 8, 9N, 9V, 10 A, 11 A, 12F, 14, 15A, 15B, 15C, 18C, 19A, 19F, 22F, 23 A, 23B, 23F, 24F, 33F, and 35B. Also provided are methods of producing the multivalent pneumococcal conjugate compositions and methods of using the same for prophylaxis against Streptococcus pneumoniae infection or disease in a subject. Also provided are immunogenic compositions comprising at least one polysaccharide-protein conjugate wherein the polysaccharide is a capsular polysaccharide from CN Streptococcus pneumoniae serotype 15A, 15C, 23 A, 23B, 24F, and/or 35B and methods of preparing the same.
