Cold room temperature mapping studies

A cold room temperature mapping study establishes the temperature distribution in cold rooms – the largest vaccine storage equipment within a country’s cold chain, generally used at central or subnational levels to store large quantities of vaccines. This evidence brief provides supply chain managers in low- and middle-income countries with examples of results of temperature mapping studies conducted in an existing cold room to control compliance, and in two newly-installed cold rooms where performance gaps were identified and addressed before vaccine was stored.
