I thought the vaccine needed to be transported at super cold temperatures. I remember that was a reason why this was considered such a complex operation. Now it seems like they are shipped the same as commercial samples. Has something changed or are the stringent shipping requirements still in place?

The vaccine, which was developed with German drugmaker BioNTech, currently needs to be stored in ultra-cold freezers that keep it between minus 112 and minus 76 degrees Fahrenheit, according to the FDA. Pfizer said it submitted new data to the U.S. agency that shows the vaccine is stable between minus 13 and 5 degrees Fahrenheit.
