Immunogenic compositions are described herein which comprise microparticles that further comprise a biodegradable polymer. The microparticle compositions also comprise a cationic polysaccharide and an immunological species selected from an antigen, an immunological adjuvant and a combination thereof. Also described are methods of making such compositions and methods of administering such compositions. Methods of modulating the release rate of immunological species from microparticles are also described. These methods comprise varying the ratio of the cationic polysaccharide relative to the biodegradable polymer within the microparticles.

La présente invention concerne des compositions immunogènes qui comprennent des microparticules elles-mêmes constituées d'un polymère biodégradable. Les compositions de microparticules comprennent également un polysaccharide cationique et une espèce immunologique sélectionnée parmi un antigène, un adjuvant immunologique et une combinaison de ces substances. La présente invention concerne également des méthodes de fabrication de telles compositions et des méthodes d'administration de telles compositions. La présente invention concerne en outre des méthodes de modulation de la vitesse de libération de l'espèce immunologique par les microparticules. Ces méthodes comprennent la modification du rapport du polysaccharide cationique sur le polymère biodégradable au sein des microparticules.
