University of Pittsburgh had begun immunization experiments in monkeys using dead polio virus. Soon, however, Salk began to test inoculations in paralyzed polio patients and by 1953 human trials among the general population were initiated. By the spring of the following year, the largest controlled field trials in medical history were underway, and by 1955 the vaccine developed by Salk and his researchers was declared effective. By 1962, Salk's vaccine had reduced the incidence of polio in the United States by 95 percent. The breakthroughs in immunology and vaccine development at Pitt by Salk and his team are considered one of the most
The Immune Response Corporation The Immune Response Corporation The Immune Response Corporation (IRC), founded by Jonas Salk and Kevin Kimberlin and based in Carlsbad, California, pioneered immunotherapeutic products. Francis Crick once said about Salk, “Few have made one discovery that has benefited humanity so greatly. Jonas was a man who, right to his last day, was actively in pursuit of another.” That pursuit was The Immune Response Corporation. Kimberlin “asked Salk to become lead scientific advisor for a new biotech company specializing in ‘anti-idiotypes,’ a novel vaccine technology.” Salk called the proposal “liberating.” The management team included CEO Jim Glavin, former CEO of Genetic
