The volume starts with a basic overview of murine and human skin dendritic cell network, respectively, and their role in immunity, as well as an extensive description of the immunobiology of the skin. The next chapter describes the state-of-the-art on delivery systems especially designed for intradermal vaccination. The remaining chapters highlight the effectiveness of intradermal immunization in experimental animal models or in clinical practice, all supporting the view that intradermal immunization is at least as good as other immunization routes.
