These three women are responsible for orchestrating an incredible breakthrough: functionally curing a newborn of AIDS. By giving the infant, who contracted HIV from its mother, anti-HIV drugs within hours of birth, Gay, a pediatrician at the University of Mississippi; Luzuriaga, an immunologist from the University of Massachusetts; and Persaud, a virologist at Johns Hopkins Children’s Center, managed to battle back the virus so the child, now 21⁄2 years old, no longer needs medications and shows no signs of HIV.
