An NIST study in 2009 determined that dormitory type refrigerators are completely inadequate for vaccine storage. The study which used 19 data loggers to record temperature in these small refrigerators concluded that: “ From these results, it is clear that the dormitory-style refrigerator can not be relied on to maintain vaccine storage temperatures, regardless of the packing density or storage containers used. The dormitory-style refrigerator’s performance was consistently unacceptable, regardless of vaccine storage location within the refrigerator”.
The study which can be seen in its entirety here proved conclusively that although there were some conditions where they might maintain the proper storage temperature for brief periods of time they were not adequate to store vaccines. Any changes made by clinic personal affecting the vaccine locations inside the refrigerator, placement of temperature recording devices, or the use of water bottles were not effective in protecting vaccines that had to be maintained at between 2°C and 8°C.
