Primary Health-Care Staff Barriers to Immunization.

Background: Missed opportunities for immunization (MOI) is considered as the most important preventable reason for underimmunization. Health-care workers stand beyond more than half the children's missed opportunities due to gaps in their knowledge, attitudes, and practices (KAP) regarding immunization.

Objectives: This study assessed immunization staff at primary health-care centers in Baghdad/Al-Karkh for KAP that may lead to MOI.
