Detailed explanation-1: -However, the poliovirus is on the verge of global eradication today – an astounding achievement of modern medicine. Jonas Salk played a pivotal role in achieving this success by being the first to devise and implement a safe and effective vaccine against polio.
Detailed explanation-2: -The results were amazing–60-70 percent prevention–and Salk was praised to the skies. But suddenly, some 200 cases of the disease were caused by the vaccine and 11 people died.
Detailed explanation-3: -The results were announced on 12 April 1955, and Salk’s inactivated polio vaccine (IPV) was licensed on the same day.
Detailed explanation-4: -Salk was new to polio research. His wartime work on influenza virus used “killed virus”. For polio, he used this same approach, applying tissue culture methods, recently developed. By 1954 it proved effective against all three strains of poliovirus.
