The United States begins the distribution of the Covid-19 Pfizer vaccine, the first to be approved by the FDA. The first doses of the vaccine were packaged in cardboard boxes with dry ice at temperatures below zero to be distributed to the different states.
The first doses of the COVID-19 vaccine packaged in cardboard boxes at below-zero temperatures are directed to distribution sites throughout the United States.
Residents of nursing homes and health workers are expected to be the first to be vaccinated.
Rapid movement is key for the vaccine, mainly because it should be stored at temperatures below -70° (94 degrees Fahrenheit below zero).
Pfizer workers didn't waste time packing. The ampoules contain the long-awaited vaccine, but the handling process in the packaging cannot allow the temperature to rise. To this end, Pfizer technicians used corrugated cardboard boxes of various litters, a very efficient thermal insulation, recyclable and with a low enough price not to impact on the final price of the vaccine.
As images show on television, the Pfizer opted for a simple and efficient process, with self-assembly boxes of corrugated cardboard a triple layer, on which a dry ice bottom was placed.
The distribution of vaccines cooled with dry ice, which must be kept at subarctic temperatures, began on Sunday and is part of a first batch with 2.9 million doses.
