Why is vaccination recommended for children?

The polio vaccine causes the body to create antibodies, which helps people establish immunity to the poliovirus infection.

This prevents sickness caused by the pathogen.

OPV (Oral Polio Vaccine) produces antibodies in the blood ('humoral' or serum immunity) for all types of polioviruses, and in the event of infection, this protects the individual against polio paralysis by preventing the spread of poliovirus to the nervous system.
