From basic principles to clinical applications on transcutaneous vaccine

Abstract

The recent vigorous transnational migration of people and materials reflecting the development of transportation facilities, changes in social structure, and war disasters has increased the global spread of emerging and re-emerging infectious diseases. Vaccine, which is the major fundamental prophylaxis against infectious diseases, has greatly contributed to the maintenance and improvement of human health worldwide. However, the disadvantages of conventional injection systems hamper the speedy mass-vaccination and the global distribution of vaccines. Transcutaneous immunization systems, which are easy-to-use and low-invasive methods of vaccination, have the potential to overcome certain issues associated with injectable vaccinations. In this review, we provide an outline of recent trends in the development of techniques for the transcutaneous delivery of vaccine antigens. We also introduce basic and clinical research involving our transcutaneous immunization systems that incorporate self-dissolving microneedle patch. © 2013 The Pharmaceutical Society of Japan.
