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 vaccines are vaccines used to prevent poliomyelitis (polio). There are two types: one that uses inactivated poliovirus and is given by injection (IPV), and one that uses weakened poliovirus and is given by mouth (OPV). The World Health Organization recommends all children be fully vaccinated against polio.
