Polio vaccine Two polio vaccines are used throughout the world to provide immunity to the virus that causes poliomyelitis (or polio). The first was developed by Jonas Salk through the use of HeLa cells and first tested in 1952.Announced to the world by Dr Thomas Francis Jr. on 12 April 1955, it consists of an injected dose of inactivated (dead) poliovirus. An oral vaccine was developed by Albert Sabin using attenuated or weakened poliovirus.ral polio vaccines were developed by several groups, one of which was led by Albert Sabin. Other groups, led by Hilary Koprowski and H.R. Cox, developed their own attenuated vaccine strains. In 1958, the National Institutes of Health created a special committee on live polio vaccines.

IPV Inactivated polio vaccine (IPV). Inactivated polio vaccine (IPV) was developed in 1955 by Dr Jonas Salk. Also called the “Salk vaccine”, IPV consists of inactivated (killed) poliovirus strains of all three poliovirus types.IPV is given by intramuscular injection and needs to be administered by a trained health worker.DC/Judy Schmidt. The inactivated polio vaccine produces antibodies in the blood to all three types of poliovirus. In the event of infection, these antibodies prevent the spread of the virus to the central nervous system and protect against paralysis.

The last cases of paralytic poliomyelitis caused by endemic transmission of wild virus in the United States occurred in 1979, with an outbreak among the Amish in several Midwest states.

Salk announces polio vaccine In 1954, clinical trials using the Salk vaccine and a placebo began on nearly two million American schoolchildren. In April 1955, it was announced that the vaccine was effective and safe, and a nationwide inoculation campaign began.

In 1962, an oral vaccine developed by Polish-American researcher Albert Sabin became available, greatly facilitating distribution of the polio vaccine.
