Objective: Immunizations are important to reduce vaccine-preventable diseases in children, and consistent control of vaccine-preventable diseases depends on fairly high immunization coverage. In order to provide effective immunization services, primary healthcare workers should have up-to-date information about immunization. This study examined the effectiveness of an intervention to increase knowledge of primary healthcare workers and vaccination coverage.
