In particular, as the mRNA vaccine becomes a major preventive vaccine in the case of COVID-19, the transportation method is being studied to meet global demand. For example, recently developed as a COVID-19 vaccine, Pfizer vaccines should be stored in the temperature range of -70℃, and similar vaccines should also be stored a -30 ℃ or below. However, existing cold storage systems are too high cost to apply storage systems below -30 ℃ and are difficult to apply in transportation. In this study, storage of direct injection using liquid nitrogen was manufactured and maintaining temperature of demanded target. In addition, vaccine storage containers were designed with considering thermal insulation, manufactured, and performance evaluations were implemented.
