William H. Foege was the former Director of the U.S. Centers for Disease Control and a founder of the Task Force for Child Survival and Development. His best known work with the Centers for Disease Control and Prevention (CDC) led to the strategy that eradicated smallpox worldwide in the late 1970s.
While faced with a shortage of vaccine and outbreaks of smallpox in Nigeria, he created the concept of targeted containment vaccination - the idea of identifying the circle of individuals who have been in contact with someone with the disease and immunizing them immediately - that proved instrumental to break the cycle of transmission of the disease, ultimately everywhere in the world.
Anthony S. Fauci is the Director of the National Institute of Allergy and Infectious Diseases (NIAID).As a researcher and government agency director, Dr. Fauci has been at the forefront of US efforts to conquer HIV/AIDS and other infectious disease in this country and around the world for more than 20 years. Under his leadership since 1984, NIAID has grown from the sixth-largest to the second-largest institute within the National Institutes of Health.
His research on the role that the body's own activated immune system plays in HIV and research demonstrating that HIV is never latent in the body or fully cleared by drugs helped to change the course of HIV/AIDS research and treatment. He has made seminal contributions to the understanding of how the AIDS virus destroys the body's defences, making the body susceptible to deadly infections. He has also been instrumental in developing strategies for treating and rebuilding the immune systems of patients with AIDS, as well as for devising strategies to create vaccines to prevent HIV infection.
