Cold storage bag for transporting coronavirus vaccines

Validated. Refrigerated transport bag for coronavirus vaccine. Keeps refrigerated (below 8°C) for 24 hours, frozen for 15 hours (below -15°C).

On March 12, 2021, at a municipal briefing held by the Health Bureau's Vaccination Division of the Ministry of Health, Labour and Welfare, it was announced that the time for transporting COVID-19 vaccines from basic vaccination facilities to satellite or collaborative vaccination facilities has been expanded to within 24 hours under frozen temperature conditions (-15 to -25°C), in addition to the existing refrigerated temperature range (2 to 8°C) within 3 hours. Particularly in rural areas, it is anticipated that transport times will exceed 3 hours, making the development of insulated bags capable of maintaining long-term frozen temperatures urgent. This product allows for dual use of refrigerated and frozen transport simply by changing the ice packs, maintaining refrigerated conditions (2 to 8°C) for 24 hours and frozen conditions (-15 to -25°C) for 15 hours in an external temperature environment of 35°C. By using this product for frozen transport and then storing the vaccines frozen at the vaccination facility, the shelf life of the vaccines, which was previously only 5 days, can be extended up to a maximum of 14 days, thereby reducing the risk of waste of valuable vaccines. It comes with a dedicated holder that can store 50 vials, cushioning material to suppress internal transport vibrations, and specialized ice packs. The exterior is made of waterproof plastic panels.
