Proper Vaccine Refrigeration Vital to Putting Disease on Ice (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption According to a NIST study, vaccines that have not been removed from their packaging (most often a cardboard box), retain their temperature longer than those that have been unpacked and placed in trays. Moreover, the standard-sized refrigerators' ability to maintain proper temperature was unaffected by how much vaccine the researchers stored in the refrigerator, a characteristic that was not shared by the dormitory style refrigerators.
