Abstract:
A method of making an intradermal injection into the skin of an animal to obtain systemic delivery or an immune response comprising the steps of:providing a drug delivery device including a needle cannula having a forward needle tip and said needle cannula being in fluid communication with a substance contained in said drug delivery device and including a limiter portion surrounding said needle cannula and said limiter portion including a skin engaging surface, with said needle tip of said needle cannula extending from said limiter portion beyond said skin engaging surface a distance equal to approximately 0.5 mm to approximately 3.0 mm and said needle cannula having a fixed angle of orientation relative to a plane of the skin engaging surface of the limiter portion; inserting said needle tip into the skin of an animal and engaging the surface of the skin with said skin engaging surface of said limiter portion such that the skin engaging surface of the limiter portion limits penetration of the needle tip into the dermis layer of the skin of the animal; and expelling the substance from said drug delivery device through the needle tip into the skin of the animal to expose the injected substance to the microcirculatory blood vasculature and the lymphatic plexuses.
