Jonas Salk worked on the polio vaccine for about eight years, from 1947 to 1955. His research began after he joined the University of Pittsburgh, and he focused on developing an effective and safe vaccine to combat the polio epidemic. Salk's efforts culminated in the successful testing and eventual widespread use of the inactivated polio vaccine in 1955.

How many people survived polio?
Polio was one of the most dreaded childhood diseases of the 20th Century in the United States. There were usually about 13,000 to 20,000 cases of paralytic polio reported each year in the US before the introduction of Salk inactivated polio vaccine (IPV) in 1955. Polio peaked in 1952 when there were more than 21,000 reported cases. The number of cases of polio decreased dramatically following introduction of the vaccine and the development of a national vaccination program. In 1965, only 61 cases of paralytic polio were reported compared to 2,525 cases reported cases just five years earlier in 1960.

How many people did the polio vaccine kill?
There are no exact figures, but, as the most common serious side effect is due to a allergic reaction to the vaccine, and that reaction occurs less than 1 time per million doses administered, the number of fatalities directly due to the vaccine itself is extremely small. The OPV (activated polio virus) causes polio just over 2 in a million times. The IPV (inactivated polio virus) does not cause polio at all. IPV is now the standard vaccine given in countries where polio is no longer present - OPV is the standard where polio is still endemic (as it is a bit more effective than the IPV in promoting resistance). Overall, in the 50+ year history of the various polio vaccines, I would estimate that the total number of deaths linked to the vaccine number in the low hundreds, almost all of them due to uncontrolled allergic reactions. Which is a very low risk, considering that upwards of 20 billion vaccines have been given.
