This document is essential and timely to help countries ensure that all COVID-19 vaccine doses are optimally utilized, and wastage is minimised. Due to the short shelf-life, several countries have faced challenges with utilizing all available doses of vaccines before the expiry date. It is of utmost importance that countries ensure the utilization of all available vaccine doses. This document enables countries to : (1) closely monitor vaccine utilization with respect to the expiry dates; and (2) proposes options for accelerating vaccine utilization, thereby mitigating the risks of closed-vial wastage. 

This was developed through a consultative process that included all the six WHO Regional Offices as well as Partner agencies supporting the rollout of COVID-19 vaccination.
