While most scientists believed that effective vaccines could only be developed with live viruses, Salk developed a “killed-virus” vaccine by growing samples of the virus and then deactivating them by adding formaldehyde so that they could no longer reproduce.

Who did Jonas Salk work for?

There in 1938 he began working with microbiologist Thomas Francis, Jr., who was looking for an influenza vaccine. They developed one that was used in the armed forces during World War II. In 1947 Salk became the head of the Virus Research Lab at the University of Pittsburgh.
