Pfizer vaccines only 20 days life difficult to transport and store
Pfizer vaccines only 20 days life difficult to transport and store. Pfizer vaccines have a shelf life of 20 days, making it difficult to transport, store, and distribute vaccines.
According to CCTV Finance, the United States plans to distribute tens of millions of doses of Pfizer’s COVID-19 vaccine within this year, but there are still many difficulties in the actual transportation, storage, and distribution. First, the vaccine needs to be stored in an ultra-low temperature -70°C, sealed, dry ice-wrapped incubator environment, during which dry ice needs to be added several times. The shelf life of the vaccine in these special “incubators” is 15 days, and after being placed in an ordinary refrigerator, the shelf life of Pfizer vaccine is only 5 days. Therefore, before and after the vaccine, the shelf life totals only 20 days.
At present, multiple freighters and passenger planes of United Airlines and National Airways have been put into the delivery of vaccines. According to the agreement, what Pfizer needs to do is to deliver the vaccine to a designated receiving point in each state according to the order quantity, and the next work needs to be completed by the state governments. Last Tuesday, President-elect Biden’s COVID-19 task force member Bright said that many states are facing huge financial and technical obstacles. It is quite difficult for the state government to successfully complete the “last mile” of vaccine delivery and final vaccination. .
