Composition stimulatory immune response comprising nanoparticles based on a copolymer of methyl vinyl ether and maleic anhydride.

stimulating composition comprising nanoparticles immune response based on a vinyl methyl ether and maleic anhydride. The stimulating composition immune response in a subject comprising nanoparticles based on a copolymer of methyl vinyl ether and maleic anhydride. Said nanoparticles may further contain an allergen or an antigen and / or an immunostimulating agent, which may be contained inside said nanoparticles and / or at least partially coating the surface of said nanoparticles, and optionally a crosslinking agent . The stimulating composition is useful as immune response adjuvant in immunotherapy and vaccines.
