Schistosomiasis: forty years' war on the worm.
Schistosome vaccine candidates are now entering phase I clinical trials. In an attempt to illustrate the progress made towards control, and the definition of potential vaccines against schistosomiasis, André Capron reviews some of the major findings and observations that have led to a significant evolution of our concepts, together with the production of novel and promising tools. It is obvious that our most important advances have proceeded from the successful integration of convergent knowledge in biology, epidemiology and biotechnology. At this stage, nobody can predict what will be the outcome of the current trials, but an important step has certainly been made towards immunointervention in human schistosomiasis.
