The first successful demonstration of a polio vaccine was by Hilary Koprowski in 1950, with a live attenuated virus which people drank. [10] The vaccine was not approved for use in the United States, but was used successfully elsewhere. [10] The success of an inactivated (killed) polio vaccine, developed by Jonas Salk, was announced in 1955.
The history of polio (poliomyelitis) infections began during prehistory. Although major polio epidemics were unknown before the 20th century, [1] the disease has caused paralysis and death for much of human history. Over millennia, polio survived quietly as an endemic pathogen until the 1900s when major epidemics began to occur in Europe. [1]
Both the Sabin vaccine (oral, live virus) and the Salk vaccine (injectable, killed virus) were affected; the technique used to inactivate the polio virus in the Salk vaccine, by means of formaldehyde, did not reliably kill SV40. The contaminated vaccine continued to be distributed to the public through 1963. [2] [3]
The recent New York patient was infected with vaccine-derived polio, a strain linked to live virus from an oral polio vaccine not administered in the U.S. It marks the first U.S. of vaccine ...
The Sabin, Koprowski and Cox vaccines were clinically tested in millions of individuals and found to be safe and effective. Because monkey trials found fewer side effects with the Sabin vaccine, in the early 1960s, the Sabin vaccine was licensed in the US and its use supported by the World Health Organization. [8]
It may cause some mild side effects, such as pain in your arm, and he suggests planning to rest for a day or two after the shot. Research shows that the vaccine is most effective in the first year ...

Polio: An American Story by David M. Oshinsky, professor of history at the University of Texas at Austin, documents the polio epidemic in the United States during the 1940s and 1950s and the race to develop a vaccine, which led to 2 different types of polio vaccine: inactivated poliovirus vaccine, developed by a team led by Jonas Salk, and oral poliovirus vaccine, developed by a team led by ...
