Clinical Trial 8317

Silver Spring, MD 20910

Study Summary:

The purpose of this study is to test the safety and effectiveness of a new malaria vaccine, called VMP001. The study is specifically looking at a vaccine against Plasmodium vivax, the most common form of malaria in Asia. This is the first time the VMP001 vaccine will be given to humans.

Background: Malaria is a parasitic disease transmitted by mosquitoes. Approximately 40% of the world’s population is at risk for malaria caused by Plasmodium vivax. This parasite causes 132 - 391 million infections around the world each year. It is a significant cause of death and disability in tropical areas of Africa, Asia, Oceania (Pacific islands) and Latin America. Humans become infected when they are bitten by infected mosquitoes. People don’t feel well with this disease – its effects are similar to the flu, with symptoms such as fever, headache, body aches, upset stomach and diarrhea. Therefore, this disease impacts people and communities due to lost time in the home, at work and school. In some parts of the world, P. vivax has become resistant to drugs used in the past, and a vaccine against this disease would therefore help people living in, or traveling to areas where it is commonly found. The U.S. Army is at the forefront of malaria vaccine research and development because soldiers are deployed to areas with malaria.
