Polio vaccines are vaccines used to prevent poliomyelitis (polio). One type uses inactivated poliovirus and is given by injection (IPV), while the other type uses weakened poliovirus and is given by mouth (OPV). The World Health Organization recommends all children be vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases each year from an estimated 350,000 in 1988 to 359 in 2014.
The inactivated polio vaccines are very safe. Mild redness or pain may occur at the site of injection. Oral polio vaccines result in vaccine-associated paralytic poliomyelitis in about three per million doses. Both are generally safe to give during pregnancy and in those who have HIV/AIDS but are otherwise well.
The first polio vaccine was the inactivated polio vaccine. It was developed by Jonas Salk and came into use in 1955. The oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961. They are on the World Health Organization's List of Essential Medicines, the most important medication needed in a basic health system. The wholesale cost in the developing world is about 0.25 USD per dose for the oral form as of 2014. In the United States it costs between 25 and 50 USD for the inactivated form.
