A systematic review of vaccine availability at the national, district, and health facility level in the WHO African Region.

Countries within the WHO African region continue to face the challenge of vaccine stock-outs at national, district, and health facility levels and this impacts on the delivery of immunization services. The frequency and the proportion of stock-outs vary between countries and between regions within a country. Countries need to put more efforts toward finding lasting solutions to vaccine shortages. We look forward to having more countries reporting vaccine stock-outs especially at the health facility level. Furthermore, countries are currently exploring different approaches for improving vaccine stock management. It is expected that in half a decade from now, more well-designed studies will be available that will inform decision-making.
