ChAdOx1.5Ag/MVA.5Ag
ChAdOx1.5Ag is a recombinant, replication deficient chimpanzee adenovirus, expressing the four antigens of the mycobacterium Esx-5a system (PPE15, PE8, EsxI, EsxJ), along with Ag85A. In mice, ChAdOx1.5Ag improved the efficacy of BCG in the lung and spleen, and a further boost with MVA.5Ag further improved efficacy in the spleen. ChAdOx1.5Ag/MVA.5Ag was also promising in non-human…
