...January, 1955, Albert B. Sabin inoculated 30 volunteers at Ohio's Chillicothe Reformatory, with a weakened strain of live polio virus. Just three months later, Jonas E. Salk announced that he had successfully tested his dead polio virus vaccine on 440,000 elementary school students, and the United States Public Health Service (PHS) licensed six companies to produce the Salk vaccine. Since then U.S. polio cases, both paralytic and non-paralytic, have fallen from 28,985, in 1955, to 650 reported...
...vaccine has been an object of medical interest and debate for over a decade. While the United States began to eradicate poliomyelitis in 1955, Dr. Sabin went on with his studies, sending his virus strains for field trials abroad where they would not interfere with the results of the Salk program. At the end of 1959, almost half the U.S. population had received a Salk shot, and already the occurrence of polio had dropped 80%. By the same time, Merck, Sharp, and Dohme Research Laboratories had shipped Sabin's live virus doses to Mexico, Czechoslovakia, Poland, Malaya, Singapore...
Farnsworth urged those who have already had Salk vaccine to have the Sabin vaccine, too. The double vaccination will give the "greatest possible immunity to polio...

The elusive virus now isolated cannot be generally used as a readymade vaccine because of the danger that children might transmit the infection to pregnant women. So scientists are trying to make it safe, by killing the virus (as in Salk polio shots) or weakening it (as in Sabin oral vaccine...
