I.The Federal State Autonomous Educational Institution of Higher Education “The Patrice Lumumba Peoples' Friendship University of Russia” of Minobrnauka of Russia (RUDN University), 117198, Moscow, Russia281020233151021102705082025Copyright © 2023,2023Nigeria, with its low routine immunization coverage and wild poliovirus reservoir, significantly contributes to overall regional burden of vaccine preventable diseases. Since introduction of the EPI in 1974 (which later became the National Program of Immunization), Nigeria’s immunization program suffered from declining coverage. The poor quality of immunization affects service utilization, even where they are provided for free, just as immunization services are. The quality assessment will provide both notion of degree of satisfaction of clients with services and framework for revision of program priorities, strategies and components Purpose of the study is to evaluate quality of immunization services provided to children in primary health centers in Oron, Akwa Ibom State, Nigeria. The study targets to identify strengths and weaknesses of immunization services, to evaluate level of compliance with national and international standards of immunization and to develop corresponding recommendations. The study seeks to contribute to body of knowledge about quality of children immunization services in Nigeria, particularly in context of primary health centers. The study may help to improve delivery of immunization services in the region and to ensure that more children will be vaccinated and protected against vaccine preventable diseases.immunizationprimary health carevaccine preventable diseasehealth managementcommunity healthpreventionиммунизацияпервичная медико санитарная помощьболезни, предотвращаемые с помощью вакцинуправление здравоохранениемобщественное здравоохранениепрофилактика1.Perin J., Mulick A., Yeung D., Villavicencio F., Lopez G., Strong K.
