Estimating the term…
The present invention relates to new immunogenic compositions comprising conjugated Streptococcus pneumoniae capsular saccharide antigens (glycoconjugates) and uses thereof. Immunogenic compositions of the present invention will typically comprise at least one glycoconjugate from a S. pneumoniae serotype not found in PREVNAR®, SYNFLORIX® and/or PREVNAR 13®. The invention also relates to vaccination of human subjects, in particular infants and elderly, against pneumococcal infections using said novel immunogenic compositions.
A 21-valent immunogenic composition comprising glycoconjugates of capsular polysaccharide from Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F and 33F individually conjugated to a carrier protein, wherein the carrier protein of the glycoconjugates respectively comprising capsular polysaccharide of serotypes 8, 10A, 11A, 12F and 33F is CRM197, and wherein the carrier protein of the glycoconjugates respectively comprising capsular saccharide of serotypes 15B and 22F is tetanus toxoid.
