Abstract
The present invention pertains generally to novel Neisseria meningitidis serogroup B glycoconjugates. More particularly, the invention pertains to glycoconjugates formed from a Neisseria meningitidis serogroup B capsular oligosaccharide derivative (MenB OS derivative) in which sialic acid residue N-acetyl groups are replaced with N-acyl groups. The invention also pertains to vaccine formulations containing the glycoconjugates, methods of making the vaccine formulations, and methods of using the vaccine formulations to treat or prevent Neisseria meningitidis serogroup B or E. coli K1 disease in a mammalian subject.
