title: Influence of immunization schedule on immunization coverage.
abstract: The infant immunization coverage for triple antigen (DPT) from 1968 and trivalent oral polio vaccine (TOPV) from 1972 to 1985 for Peninsular Malaysia are presented. It shows that immunization coverage improved when the recommended age for first dose of DPT was changed from the fourth to the second month of life in 1972 and declined when the recommended age for the first dose of DPT and TOPV was revised again from the second to the third month of life in 1980. The advantages of immunizing children early in life are discussed.
