Summary

The Covid-19 pandemic has accelerated research to develop vaccines against the SARS-CoV-2 virus. All heat-sensitive vaccines have storage temperature managed by using available active or passive refrigeration means, but the first Covid-19 vaccine developed must be stored and transported between -90 °C and -60 °C. The eutectic solutions traditionally used for -25/-15 °C range cannot meet this need, because they do not offer melting temperatures close to -70 °C. With a sublimation enthalpy of 573 kJ.kg-1 at -78.5 °C, dry ice is the best way to secure the cold chain of these vaccines. In this article, we analyse standalone solutions of insulated boxes using dry ice, allowing to transport safety the vaccines between -90 °C and -60 °C. The performance of the solution and the necessary amount of dry ice depend on the quality of the thermal insulation, the size of the box, the required cooling duration (autonomy) and the ambient temperature.
