  • Patent number: 9011870
    Abstract: The invention relates to the areas of immunology and vaccine delivery. More specifically, it relates to a bacterial vaccine delivery technology with built-in immunostimulatory properties which allows the immobilization of any antigen of interest, without prior antigen modification. Provided is an antigen-loaded immunogenic carrier complex comprising at least one bifunctional polypeptide attached to an immunogenic carrier, said bifunctional polypeptide comprising a peptidoglycan binding domain (PBD) through which the polypeptide is attached to said carrier, fused to an antigen binding domain (ABD) to which at least one antigen of interest is bound.
