Abstract
An immunogenic conjugate comprising a modified group C meningococcal polysaccharide (GCMP) coupled to a carrier molecule. The GCMP is modified by O-deacetylation to a varying extent. This modified GCMP conjugate stimulates a strong immunogenic response. The antiserum, produced by immunization with this conjugate, is cross-reactive with the native polysaccharide. In addition, these antisera elicit a class of antibodies that have patent bactericidal activity.
