Conjugate Vaccine
Definition 1
A category of vaccines created by covalently attaching an antigen from an organism to a carrier protein from the same organism to aid in the delivery of the immunogen. (NCI Thesaurus)
Definition 2
Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognized by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection.
