Pfizer-BioNTech Vaccine Is Highly Effective After One Dose and Can Be Stored in Normal Freezers, Data Shows - WSJ wsj.com/articles/singl…
"The findings provide strong arguments in favor of delaying the second dose of the two-shot vaccine, as the U.K. has done. They could also have substantial implications on vaccine policy and distribution around the world, simplifying the logistics of distributing the vaccine."
"A single shot of the vaccine is 85% effective in preventing symptomatic disease 15 to 28 days after being administered, according to a peer-reviewed study conducted by the Israeli government-owned Sheba Medical Center and published in the Lancet medical journal."
"Preliminary data also suggest that the other widely used vaccine in the U.K. developed by AstraZeneca PLC and the University of Oxford could have a substantial effect after a first dose."
"Separately, the vaccine, which has been authorized in the U.S., the U.K., the EU and elsewhere, can be stored and transported at between minus 25 and minus 15 degrees Celsius, or minus 13 and 5 degrees Fahrenheit—similar to a consumer freezer—Pfizer and BioNTech said."
