A convoy of trucks loaded with suitcase-sized containers containing the Covid-19 vaccine set off Sunday morning from Pfizer’s manufacturing complex in Kalamazoo, Michigan, at the start of the largest and toughest vaccine distribution project in the United States.
On Friday evening, the relevant US authorities approved the use of the vaccine produced by Pfizer and Biontech, and security officers will accompany the shipments since leaving the factory until it reaches its final destination.
Each container cooled with dry ice contains up to 4,875 doses of the vaccine and will be transported to planes near the factory that will in turn transport them to United Parcel Service and FedEx air cargo centers in Louisville, Kentucky, and Memphis, Tennessee.
From there, it will be transported by trucks or planes for distribution to the 145 sites designated by the United States to receive the first doses.
It was decided that health care workers and the elderly residing in nursing homes would be the first batch to be immunized with the vaccine.
Pfizer requires keeping the vaccine at minus 70 degrees Celsius.
