A pilot study in Uganda showed a significant improvement in vaccine delivery efficiency and quality through implementing an informed push model. The specific goals of the pilot were to improve vaccine lead time, standardize cold chain management during transportation, and evaluate the costs of implementing the informed push model in Gomba district, Uganda.
The findings showed that the average lead-time for vaccine delivery reduced from 14 days at baseline to 5 days at endline, and timely vaccine receipt at health facilities increased from 37% to 100%. The proportion of facilities experiencing stock-outs more than halved from 79% to 37%. Monthly distribution costs decreased from $494.8 ($0.07 per child) to $445.9 ($0.06 per child). The informed push model was found to be a cost-effective strategy for improving last-mile vaccine delivery by reducing lead times, enhancing cold chain management, and decreasing stock-outs. Integration into the national immunization program is recommended for broader adoption in Uganda.
