Abstract
A transdermal liposome system delivers antigen to immune cells without perforation of the skin, and induces an immune response in an animal or human. The system uses liposomes to deliver a variety of antigens which can elicit an antigen-specific immune response (e.g., humoral and/or cellular effectors) after topical application of a formulation containing liposomes and antigen to intact skin of the animal or human.
