Patent number: 12144855Abstract: A method is described for producing a pneumococcal capsular polysaccharide protein conjugate in which one or more activated pneumococcal polysaccharides of particular pneumococcal serotypes and carrier protein are separately lyophilized in the form of lyospheres of carrier protein and lyospheres of the one or more polysaccharides. A predetermined amount of carrier protein lyospheres and activated polysaccharide lyospheres are mixed together and the mixture reconstituted in an organic solvent to produce polysaccharide carrier protein conjugates. A plurality of conjugates, each comprising polysaccharides of a particular serotype, may be used to produce multivalent pneumococcal immunogenic compositions having a combination of conjugates for use in vaccines.Type: GrantFiled: April 25, 2019Date of Patent: November 19, 2024Assignee: Merck Sharp & Dohme LLCInventors: Patrick Leonard Ahl, Akhilesh Bhambhani, Christopher Jon Farrell, Patrick McHugh, Morrisa C. Jones, Daniel D. Roth, Jessica R. Sinacola, Justin Stanbro, Matthew P. Watson, Emily Wen, Michael A. Winters

Publication number: 20210048247Abstract: Methods for preparing dried pellets of biological materials are described.
