VACCINE AGAINST GROUP B STREPTOCOCCUS COMPRISING A GROUP B STREPTOCOCCUS POLYSACCHARIDE CONJUGATED TO A FUNCTIONAL DERIVATIVE OF GROUP B STREPTOCOCCUS C PROTEIN ALPHA ANTIGEN

摘要

A vaccine capable of protecting a recipient from infection caused by group B Streptococcus. The vaccine provides polysaccharide-protein moieties and contain (a) a group B Streptococcus polysaccharide conjugated to (b) a functional derivative of a group B Streptococcus C protein alpha antigen that retains the ability to elicit protective antibodies against group B Streptococcus. The vaccine may contain only one type of such polysaccharide-protein unit or may contain a mixture of more than one type of unit.
