Broadly Protective Protein-Based Pneumococcal Vaccine Composed of Pneumolysin Toxoid-CbpA Peptide Recombinant Fusion Protein
Pneumococcus, meningococcus and Haemophilus influenzae cause a similar spectrum of infections in the ear, lung, blood, and brain. They share cross-reactive antigens that bind to the laminin receptor of the blood-brain barrier as a molecular basis for neurotropism, and this step in pathogenesis was addressed in vaccine design. This article, published in the Journal of Infectious Diseases, reports results from a study where biologically active peptides derived from choline-binding protein A (CbpA) of pneumococcus were identified and then genetically fused to L460D pneumolysoid. The fusion construct was tested for vaccine efficacy in mouse models and results showed that the CbpA peptide-L460D pneumolysoid fusion was more broadly immunogenic than pneumolysoid alone and antibodies were active in vitro against all three bacteria.
