The Pfizer / BioNTech vaccine needs to be stored at about minus 75 degrees Celsius – much colder than any vaccine currently used in the US.
Pfizer announced the possibility that the first shipment of the anti-COVID-19 vaccine would start moving from its Michigan facility on Sunday morning, according to the Vietnam News Agency correspondent in the US.
