"When reading the temperature loggers that were enclosed in the cool boxes, doubts arose about the compliance with the cold chain requirements," the district of Lichtenfels in the north of Germany's largest state Bavaria said in a statement. Once out of ultra-low temperature storage, the vaccine must be kept at 2C to 8C to remain effective for up to five days. The cool boxes designed by Pfizer are fitted with GPS trackers so the companies can deal with potential storage issues en route. "Vaccination against the coronavirus is not about who vaccinates the fastest or who does the most doses. Safety and conscientious work for the benefit of the population has the highest priority," said Oliver Baer, district administrator in Hof.
