"Four reasons for encouragement based on Pfizer’s Covid-19 vaccine results"

This is at the end of the report:

quote Pfizer’s vaccine will almost certainly be the first to be authorized by the FDA. But it’s also going to be the hardest one to use. The vaccine has to be shipped and stored at ultra-cold temperatures, -94 Fahrenheit (-70 Celsius). That requirement will limit where the vaccine can be used. Moderna’s mRNA vaccine must be stored at -4 F (-20 C), which is not ideal, but not quite as challenging. Still, a vaccine that might be 90% efficacious becomes more attractive — regardless of distribution challenges. Moncef Slaoui, co-chair of Operation Warp Speed, told STAT last week that the storage requirements have been a topic of discussion between the U.S. government and Pfizer. The Pfizer vaccine is not being developed as part of Operation Warp Speed, but the U.S. has pre-purchased 100 million doses of it, with an option to buy an additional 500 million more. “There were tradeoffs in their case between the speed with which vaccine would be available and identifying the right formulation that would be stable,” Slaoui said. “Both [Pfizer and Moderna] are working on improving the stability, the cold chain requirements to at least 2 C to 8 C degrees,” he said, referring to standard refrigerator temperature in Celsius. “And I am confident they will find solutions.”
