| abstract |
An immunogen-specif ic adjuvant for a vaccine or inoculum is disclosed. The adjuvant is comprised of particulate recombinant protein body-like assemblies (RPBLAs) that contain a recombinant fusion protein that contains two portions peptide-linked together. A first portion is a protein body-inducing sequence (PBIS) and a second portion is a T-cell stimulating immunogenic polypeptide whose sequence is that of a pathogenic polypeptide sequence present in or induced by a vaccine or inoculum. The adjuvant, when used as an inoculum in a host animal without a prior priming vaccination or inoculation, does not induce production of antibodies or T cell activation to the pathogenic sequence. |
