Dr. Jonas Salk,the medical pioneer who developed the first polio vaccine, died of heart failure in La Jolla, Calif. this afternoon. Salk became a hero to millions of Americans in the 1950s when he ignored scientific doubters and used killed virus to develop the polio vaccine. Similarly, he ignored skeptics later in life when he tried to devise a vaccine-like treatment for AIDS.
