description The present invention relates to an immunogenic composition including multivalent pneumococcal polysaccharide-protein conjugates. Each conjugate includes capsular polysaccharides of different pneumococcus serotypes conjugated to a carrier protein. More concretely, the present invention is a multivalent immunogenic composition including polysaccharide-protein conjugates. Each of the polysaccharide-protein conjugates includes Streptococcus pneumoniae-derived capsular polysaccharides of different serotypes conjugated to a carrier protein. The capsular polysaccharides include a) capsular polysaccharides of one or more serotypes selected from the group consisting of serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, and b) capsular polysaccharides of one or more serotypes selected from the group consisting of serotypes 10A, 11A, 12F, 15B, 22F, 23A, and 35B. The multivalent immunogenic composition according to the present invention is capable of inducing an immune reaction against a wider variety of serotypes than the conventional Prevenar 13. In particular, the conventional Prevenar 13 is designed mainly for serotypes frequently appearing in Europe and North America, but the immunogenic composition of the present invention is an immunogenic composition having high coverage not only in Europe and North America but also throughout Asia. Therefore, the multivalent immunogenic composition according to the present invention is capable of being beneficially used to prevent diseases caused by pneumococcus in infants, children, and adults.
