POLYSACCHARIDIC FRAGMENTS OF STREOTOCOCCUS TYPE II AND TYPE III FROM ANTIGENIC GROUP B PROCESSING TERMINAL STRUCTURE OF 2,5-ANHYDRO-D-MANNOSE AND CONJUGATED CAVVINE MADE ON THEIR BASIS

摘要

The process for depolymerizing Group B Types II and III Streptococcal Polysaccharide is disclosed which results in polysaccharide fragments having a reducing end suitable for conjugating to protein. Conjugate molecules, vaccines and their use to immunize mammals including humans are also disclosed.
