Safety and efficacy of transcutaneous vaccination using a patch with the live-attenuated measles vaccine in humans

Transcutaneous immunisation (TCI) using a skin patch is a non-invasive vaccination route relevant to mass vaccination against infectious diseases. This phase I/II clinical study, documents that TCI of human adult volunteers with the live-attenuated measles vaccine ROUVAX((R)) is safe and poorly reactogenic. It promotes induction of measles-specific salivary IgA and a tendency to increased frequency of NIV-specific IFN-gamma-producing T cells. However, in contrast to the subcutaneous route, TCI failed to evoke neutralising NIV-specific serum antibodies. Thus, alternative delivery methods and/or devices providing optimal uptake by skin DC should be considered for live-attenuated virus vaccines, such as the measles vaccine. (C) 2007 Elsevier Ltd.
