what vaccination protects against polio?
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.
