Abstract
A conjugate, which is the reductive amination product of an immunogenic capsular polymer fragment, having a reducing end and derived from the capsular polymer of a bacterial pathogen, and the non-toxic polypeptide binding subunit of the heat-labile enterotoxin of Escherichia coli (LT-BNT). Also disclosed, are methods for the preparation of the conjugates and for the preparation of vaccines containing the conjugates which elicits an effective level of antibodies in humans. By administering an immunogenic amount of the conjugates, active immunization against systematic infection in young mammals caused by bacterial pathogens can be induced.
