Compositions and methods for treating or preventing pneumococcal infection

摘要

The invention provides polypeptides, polysaccharide-polypeptide conjugates, and expression vectors for treating or preventing pneumococcal infection. The compositions induce an anti-pneumococcal immune response when administered to a mammal. The compositions can be used prophylactically to vaccinate an individual and/or therapeutically to induce a therapeutic immune response in an infected individual.
