The development of effective vaccines to prevent paralytic polio was one of the major medical breakthroughs of the 20th century. Two different kinds of vaccine are available, an inactivated (killed) polio vaccine (IPV) and a live attenuated oral polio vaccine (OPV). The presence of neutralizing antibody against polioviruses is considered a reliable correlate of protection against poliomyelitis.
Polio affects the central nervous system and spinal cord. It can cause muscle weakness and paralysis. Polio is a life threatening condition because it can paralyze the muscles that help you breathe. The polio vaccine is used to help prevent these diseases in children and adults. This vaccine works by exposing you to a small dose of the virus, which causes the body to develop immunity to the disease.
