OBJECTIVES: Immunization dose was considered as a late immunization dose if it was administered after the recommended age. The aims of this study are to determine the frequency and percent of this type of doses among child immunization schedule, and to determine the number of late immunization dose received by each child.  METHODS: Data was collected retrospectively from 528 children immunization cards in Iraq to obtain the immunization history of each individual child. This study was restricted the analyses to the vaccines administered before age 2 years. Each children must received seven doses at seven times, every dose consist of many types of vaccines.   RESULTS: More than 63% of late immunization doses were shown in the third dose (OPV+DTP) at fourth month of child life. Hundred and forty five children were immunized with four late immunization doses out of seven immunization doses, and 1.5% of children were immunized with 7 late immunization doses.  CONCLUSIONS: This study found that compliance with WHO immunization recommendations is low and inappropriate immunization doses were occur frequently, and leading to incomplete or partial immunization compliance. With an increase in parent’s knowledge of immunization guidelines against infectious agents, it is very important to implement strategies that will lead to improved and developed immunization practice and childhood immunization coverage in the future.
