  • Patent number: 11992521
    Abstract: 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, the separately lyophilized polysaccharides and carrier protein are separately reconstituted in an organic solvent, and the reconstituted polysaccharide and carrier protein are then combined together by Tee-mixing and conjugated together 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.

  • Publication number: 20210048247
    Abstract: Methods for preparing dried pellets of biological materials are described. The pellets can have a substantially spherical shape and are prepared by freezing droplets of a liquid composition of a desired biological material on a solid surface followed by microwave vacuum drying the frozen droplets. These methods are useful for preparing dried pellets having a high concentration of a desired biological material, in particular a therapeutic protein or vaccine, and which have a faster reconstitution time than lyophilized powder cakes prepared in vials.
