Experimental leishmaniasis vaccine could overcome challenge of multiple species

Most of the 12 million people currently infected with leishmaniasis worldwide are also afflicted with poverty. The ‘black fever’ is caused by a single-cell parasite that gets passed from one person to another by the bite of a tiny sand fly and produces disfiguring skin lesions, severe mouth and throat ulcers, or swollen internal organs. In 2005, the ministers of India, Bangladesh, and Nepal committed to a ten-year plan to eliminate infections of Leishmania in their region. Two years later, the World Health Organization (WHO) adopted a resolution to take control of the disease.
