Overview: from the horse experimentation by Prof. Akira Fujinami to paramyosin.
Professor Akira Fujinami demonstrated for the first time in the world that acquired immunity might be induced against macroparasites such as schistosomes. Since then, vaccination models have been developed using various species of animals, among which the attenuated vaccine model in the mouse has been utilized mostly to clarify immune effector mechanisms and define candidate vaccine molecules. However, further studies are necessary on immune responses to defined parasite molecules in humans, because some discrepancies in immune responses still exist between animals and humans, and apparently genetic influence should be taken into consideration in such studies on defined molecules. Despite of some limitations, vaccine trials in livestock against Schistosoma japonicum may provide useful information for development of vaccines against the other human infections caused by S. mansoni or S. haematobium. In this overview, studies carried out mainly by Japanese investigators towards vaccine development will be described.
