maintains an international listing of clinical research trials including trials on
infectious diseases and on malignant melanoma, for which there is much current hope that

The European Commission Database on European Vaccine Research, designed to facilitate the flow of information on vaccine research and development in Europe, is a well-thought-out website that should be of value to researchers around the world, as well as to practitioners interested in vaccine trials.
Ongoing NIH Clinical Research Studies can
be searched on a special
