Study design this study was restricted the analysis to types of vaccines administered before 2 years of age. A cohort study of 528 pediatrics born between 1st January 2003 and 31st Jun 2008 was selected. Immunization history of pediatric was collected retrospectively from pediatric immunization card.

Results: Less than half of pediatric were considered as partial immunization with noncompliance. 3696 immunization doses must receive by 528 pediatric, 25.3% of doses were normal doses, 8.3% as an early doses, 13.6% as a missed doses, 47.5% of doses were late doses, and 5.3% as an extra doses.
