Inactivated Polio Vaccine
Polio vaccination is highly effective in producing immunity to poliovirus and protection from paralytic poliomyelitis. Approximately 90 percent or more of polio vaccination recipients develop protective antibodies to all three poliovirus types after two doses, and at least 99 percent are immune following three doses.
Most people who get the polio vaccination develop no side effects. However, a vaccination, like any medicine, can cause side effects.
Most polio vaccination side effects are minor, meaning that the symptoms improve on their own or are easily treated by the healthcare provider. In rare cases, polio vaccination side effects can be more serious. Very rarely, they can cause severe harm or death. Getting polio vaccination is much safer than getting polio.

No wild polio has been reported in the United States for over 20 years. But the disease is still common in some parts of the world. It would only take one case of polio from another country to bring the disease back if we were not protected by polio vaccination.
If the effort to eliminate the disease from the world is successful, some day we won't need polio vaccination. Until then, we need to keep getting our children vaccinated.
