Abstract
A composition as disclosed is comprised of a plurality of particles and a pharmaceutically acceptable carrier. The particles are comprised of (1) an adjuvant; (2) a biocompatible polymer which maybe a co-polymer such as PLGA, and (3) a peptide of a sequence of interest, e.g. a sequence which corresponds to a sequence presented on a surface of a cell infected with a virus. The carrier includes an adjuvant such as a monophosphoryl lipid A (MPL) different from the adjuvant in the particles. The particles may be sized such that they are sufficiently large so as to prevent more than the contents of a single particle from being presented to a single immune system cell.
