LONDON/NEW YORK/TOKYO -- As coronavirus vaccines start to come on the market, countries are rushing to tackle the unique logistical challenges presented by worldwide distribution at the ultralow temperatures needed to keep them stable, with developing Asian countries facing some of the most difficult issues.
The vaccine from Pfizer and BioNTech is being transported via planes and trucks from a Pfizer production facility in Belgium to the rest of the world. Specially built boxes can store 1,000 to 5,000 doses at the necessary temperature of minus 70 C for up to 10 days, and can be tracked via GPS. Meanwhile, the vaccine developed by Moderna also must be stored at subzero temperatures, but at minus 20 C.
