Infants should be given three doses, the first at 2 months of age, followed by two more doses at 8-week intervals. A fourth dose should be given at age 18 months unless poliomyelitis is endemic in the area, in which case the fourth dose is given 6 to 12 months after the third. Additional doses are recommended prior to school entry and then every 5 years until age 18.
