Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
The vaccine also prevents almost all severe cases of the disease. About 25–30% of the people who develop chickenpox after vaccination will experience a case that is as severe as those of unvaccinated people. [42] Side effects of the vaccine can include: soreness, redness and/or rash at the injection site (1 in 5 children) fever (1 in 10 or fewer)
Polio-like syndrome is a general description of a group of symptoms which mimic polio, including rarely permanent paralysis.

[1] [2] These are suspected in many cases of acute flaccid myelitis.

Poliovirus, the causative agent of polio (also known as poliomyelitis), is a serotype of the species Enterovirus C, in the family of Picornaviridae. [1] There are three poliovirus serotypes, numbered 1, 2, and 3. Poliovirus is composed of an RNA genome and a protein capsid.
Oral polio vaccines were developed in the late 1950s by several groups, including those led by Albert Sabin, Hilary Koprowski and H. R. Cox. [8] A poliovirus type 1 strain called SM was reported in 1954. A less virulent version of the SM strain was reported by Koprowski in 1957.
