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).
These antibodies protect you from illness should you become infected with the polio virus. The vaccine is safe to be given if you are pregnant or breast-feeding. Before 2004, the polio vaccine was given as drops into the mouth. It is now always given as an injection. If you have previously started a course of polio immunisation with oral vaccine you can finish off the course with polio injections. You do not need to start again. Polio immunisation timetable
