Stimulating composition of the immune response that includes nanoparticles based on a copylimer of methyl vinyl eter and maleic anhydride.

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