New study shows Pfizer coronavirus vaccine 85% effective after single dose

A single dose of Pfizer's coronavirus vaccine was found to be 85% effective 15-28 days after being administered according to an Israeli study published in the peer-reviewed medical journal The Lancet (source). A two-dose regimen of the vaccine was found to be 95% effective in clinical trials last year, but some countries (including the UK) have experimented with delaying the second dose in an effort to provide at least one shot to a higher volume of people.

Extra: Meanwhile, Pfizer submitted data to the FDA yesterday showing that its coronavirus vaccine can be stored at standard freezer temperatures for two weeks (as opposed to “ultra-cold” temperatures between -76 and -112 degrees Fahrenheit).
