polio Vaccine Question #2:

How effective is the vaccine?

The vaccine is close to 100% effective when all doses are administered.

IPV-containing vaccines produce immunity to all three types of poliovirus in over 95% of vaccinees following three doses of vaccine, and in close to 100% following a booster dose. Seroconversion rates are lower if the minimum age and minimum intervals for vaccine administration are used in infants less than 6 months of age.
