Industrial freezers first created to ship perishable foods like fresh tuna to Japan have been retrofitted to ship the newly-approved Pfizer COVID-19 vaccine.
The doses can be transported in freezers like those from Thermo King, which have been proven to keep supermarket- and restaurant-grade tuna at -76 degrees Fahrenheit as it travels overseas, CNN reported.
The vaccine has to stay ice-cold to remain effective, since it uses a new kind of immunization technology called mRNA, or messenger RNA.
Thermo King, an industrial refrigeration company that s created shippable freezers for sending temperature-sensitive fresh tuna fish to Japan, has found a new use for its food-safety technology: COVID-19 vaccine shipments.
