Oral poliovirus vaccine (OPV) contains live attenuated poliovirus (Sabin strain types 1, 2 and 3) and is intended for polio prophylaxis in infants 6-12 weeks of age, all unimmunized children up to 18 years of age, and high-risk adults. Adults, however, should receive the inactivated poliovirus vaccine (IPV).
Polio vaccine comes in two forms as mentioned above: oral which has live weakened virus and injectable which contains live killed virus. Both IPV and OPV offer almost 100% immunity to the recipient in industrialized countries. Regardless of the type of Polio Vaccine used, the dosing schedule is nearly the same. It is usually given in a series of 4 doses at 2 months, 4 months, 6-18 months and again between 4-6 years of age. In endemic countries, a dose is also given at birth.
