Vaccinal preparations comprising an antigen such as tumor-associated antigens and viral antigens, together with a hydrophobized polysaccharide as adjuvant, e.g., hydrophobized polysaccharides containing a saccharide unit whose primary hydroxyl group is represented by the following formula: -O-(CH2)mCONH(CH2)nNH-CO-O-R wherein R represents an alkyl group or a sterol residue; m represents 0 or 1; and n represents an arbitrary positive integer, at a ratio of one to five units per 100 saccharide units that constitute the polysaccharide, preferably comprising an antigen encapsulated in microparticles of aggregated hydrophobized polysaccharide.
