Abstract From the Canadian patent

The present invention relates to novel T-cell epitopes of bacterial products. The epitopes of the invention may be employed in the preparation of conjugates between the epitopes and medically useful antigens haptens, or antigenic determinants. These conjugates are capable of eliciting antibody responses similar to conjugates of antigens covalently coupled to carrier proteins, and in a vaccine composition provide a, safe and more economic conjugate vaccines.
