Disclosed is an immunogenic composition having 13 different polysaccharide-protein conjugates. Each conjugate contains a capsular polysaccharide which is prepared from different serotypes of streptococcus pneumonia conjugated to a carrier protein, in particular 12 serotypes selected from the group consisting of serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F, and serotypes 22F or 33F. The immunogenic composition formulated as a vaccine having an aluminum-based adjuvant increases coverage against pneumococcal disease in infants and young children. |
