US Freezers Aren’t Cold Enough to Store One Major Coronavirus Vaccine
Ultra-cold freezers are suddenly a hot commodity. One of the most advanced US coronavirus vaccines, created by Pfizer in partnership with BioNTech, has to be stored at -70° Celsius (-94° Fahrenheit), or around 30°C colder than the North Pole in winter. It’s far from certain that the vaccine will be approved for widespread distribution. But if it is, very few freezers go that cold.
