IPV: Inactivated polio vaccine. The polio virus in IPV has been inactivated (killed). The inactivated polio vaccine (IPV) is also called the Salk vaccine after the late American physician-virologist Jonas Salk.
IPV (inactivated polio vaccine) is given as a shot in the arm or leg.
OPV (oral polio vaccine) is the preferred vaccine for most children. As its name suggests, it is given by mouth. Infants and children should be given four doses of OPV. The doses are given at 2 months, 4 months, 6-18 months and 4-6 years of age.
Persons allergic to eggs or the drugs neomycin or streptomycin should receive OPV, not the injectable IPV. Conversely, IPV should be given if the vaccine recipient is on long-term steroid (cortisone) therapy, has cancer, or is on chemotherapy or if a household member has AIDS or there is an unimmunized adult in the house.
