Definition of Polio immunization

Polio immunization: One of the two polio vaccines that are available: oral polio vaccine (OPV) and inactivated polio vaccine (IPV). OPV was formerly recommended for children in the US but was shown to actually cause polio in extremely rare cases and is no longer recommended. IPV is given as a shot in the arm or leg.
