Health workers' knowledge on Immunization Service Delivery

Immunization is one of the most cost-effective public health interventions and has been shown to avert more than two million deaths annually. Newer vaccines have been added to the initial six antigens that were available at the launch of Expanded Programme on Immunization in 1974. Nigeria adopted a phased introduction of the pentavalent vaccine in 2012 and as part of the pre-introduction activities health workers workers’ knowledge on service delivery were refreshed by the training on the pentavalent vaccine. The study showed that the training had positive influence on knowledge of health workers on service delivery and refresher trainings were recommended for the health workers to build their capacity.
