Vaccine composition

摘要

The invention concerns a vaccine composition comprising at least an antigen, a cationic lipid and an immunostimulatory oligonucleotide. Said vaccine composition is particularly designed to induce an immune response of the Th1 type and a cytotoxic T response when administered by parenteral delivery, and to induce a Th2 type immune response when delivered through the mucous system. Said composition is of particular interest when the cationic lipid is DC chol.
