EVM assessments are created and delivered using a sophisticated yet practical set of online and offline tools. Each country in the world has a secure web portal to manage its EVM environment and create and deliver assessments. Data collection is conducted using the EVM Assessor mobile app, which also contains a library of supply chain resources and tools, including the VVM Guide. This tool provides guidance to users on how to read a Vaccine Vial Monitor (VVM) and use this information to estimate vaccine discard times.
