Abstract

Compositions and methods for enhancing antigen-specific immunity in a subject are provided. Pharmaceutical compositions including an effective amount of an immuno-stimulatory cardiolipin as an adjuvant in combination with an antigen and methods of use thereof for stimulating protective immunity to the antigen in a subject are provided. Administration of the combination of the antigen and cardiolipin adjuvant is effective to enhance antigen-specific immunity in a subject to a greater degree than administering to the subject the same amount of the antigen alone. The active agents can be administered together or separately. In preferred forms the cardiolipin is cardiolipin species (C18:2)4. In preferred forms the antigen is formulated as a vaccine, such as an influenza vaccine. A preferred amount by weight of each reagent is about 10-40% cardiolipin to about 90-60% antigen(s), inclusive.
