Abstract

Each year, billions of dollars of vaccines are stored in refrigerators at the facilities of a variety of medical providers. Many vaccines must be maintained in the range 2 °C to 8 °C to retain product potency. As an extension to our study of household and pharmaceutical-grade refrigerator models used for this purpose [1,2], we have evaluated the performance of a small, under-the-counter pharmaceutical refrigerator model for vaccine storage use. This unit [capacity = 0.138 m3 (4.9 cu ft)] proved fully adequate at maintaining vial temperatures within the desired 2 °C to 8 °C range, independent of how the refrigerator was loaded and under variable use and environmental conditions.
