"The Department of Health and Human Services has responded vigorously to emerging infectious diseases, including West Nile Virus, and we aim for the earliest and best possible protection for Americans," says HHS Secretary Tommy G. Thompson. "We will continue aggressive research and development steps, and we will continue to work with our public health partners toward preventing mosquito-borne disease and ensuring effective prevention and treatment."
"West Nile is one of the emerging infectious diseases for which we are developing novel preventive and therapeutic tactics," says NIAID Director Anthony S. Fauci, M.D. "Because our researchers have more than a decade of experience working with this class of virus, they could respond very quickly to the urgent public health need for a promising West Nile virus vaccine."
