Reducing the loss of vaccines from accidental freezing in the cold chain: the experience of continuous temperature monitoring in Tunisia.

Lloyd J, Lydon P, Ouhichi R, Zaffran M - Vaccine (2014)

Bottom Line: Lastly, the solutions implemented reduced risk of freezing during transport from 13.8% to 1.7%.Although the solution implemented is not optimal in the longer term because domestic refrigerators are used extensively in district stores and health centers, the risk of accidental freezing is significantly reduced by introducing the practice of continuous temperature monitoring as a standard.The management of the cold chain equipment was strengthened as a result which helps protect the potency of vaccines to the areas of most difficult access.

Mentions: Following the steps of distribution in (see Fig. 1), transport of vaccines in Tunisia is traditionally done in domestically produced picnic cooler boxes filled with frozen-water packs to keep the temperatures in the correct ranges. Given that compliance for conditioning ice-packs and adequately packing vaccines is limited vaccines are often placed right next to, or on-top of a frozen water pack. This practice increases the risk of vaccine freezing during transport.
