Abstract:

Immunization is a cornerstone of public health policy and is demonstrably highly cost-effective when used to protect child health. Vaccines have transformed today’s public health system. The potency and effectiveness of vaccines lie primarily in their handling and cold chain management systems. The success of national immunization programmes depends largely on effective logistics management of the vaccine cold chain system. The novelty of this study is to thoroughly explore the Vaccine Cold Chain management practices among Routine Immunization service providers in Sokoto State and find interrelationships between the determinants. A descriptive cross-sectional study design was employed and 230 equipped health facilities were sampled, where facility-based, mixed self-reported and actual practice evaluations were made; Analysis of the results by Chi-square test revealed the level of education, years of experience, Attendance of Vaccine Cold chain management related trainings, supportive supervision of RI Service provider determined their Vaccine cold chain management practices. According to the study, Routine Immunization Service providers need to be re-trained periodically in Vaccine cold chain management to keep them in tune with the most recent information for optimal service delivery, The health facility in charge provides the needed oversight on Routine Immunization service providers; and Supportive supervision to be prioritized and owned by the State.
