The action of oral polio vaccine (OPV) is two-pronged.

Can you get polio twice?

Does past infection with polio make a person immune? There are three types of polio virus. Lifelong immunity usually depends on which type of virus a person contracts. Second attacks are rare and result from infection with a polio virus of a different type than the first attack.

Is polio vaccine active or passive immunity?

What is vaccine-derived polio? Oral polio vaccine (OPV) contains an attenuated (weakened) vaccine-virus, activating an immune response in the body. When a child is immunized with OPV, the weakened vaccine-virus replicates in the intestine for a limited period, thereby developing immunity by building up antibodies.

Why polio vaccine is given again and again?

The oral polio vaccine is effective as it not only protects the children from contracting the virus, but also prevents them from carrying the virus in their intestines. Several doses need to be given spaced apart to build sufficient immunity, especially in areas where poor nutrition can weaken immune systems.
