At the Rockefeller Institute for Medical Research in New York, Simon Flexner, MD (1863-1946), showed that “germicidal substances” were present in the blood of monkeys that had survived polio. Other researchers reported similar results with humans. These substances were neutralizing antibodies to polio. Researchers took this finding to indicate that a vaccine might be used to induce antibody production to fight the virus.
