...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...
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...

...trivial disease-totally different from ordinary measles (rubeola). 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...
...Step Further. Even before Cleveland began to gulp down the live-virus oral Sabin vaccine, killed-virus Salk vaccine had compiled an enviable record in suppressing polio. In the last seven years, Salk vaccine has cut Cleveland's polio to a total of 417 cases, compared with 3,338 in the previous seven years. But, says Dr. Howard H. Hopwood of the Academy of Medicine, the Sabin method has important advantages over Salk in mass vaccination campaigns. The live virus can be given by mouth, rather than by needle. It not only builds up polio-fighting antibodies...
