After nine grueling months of fear, fumbling, devastation and death, the last 24 hours have been the most hopeful of the entire pandemic.
On Tuesday, a 90-year-old Briton became the first person in the world to receive a clinically authorized, fully tested coronavirus vaccine. A few hours later, the U.S. Food and Drug Administration confirmed that the same vaccine, made by Pfizer and BioNTech, is safe and 95 percent effective. On Thursday the FDA’s vaccine advisory group will almost certainly approve the Pfizer vaccine, and by week’s end the first Americans should be getting inoculated. Other vaccines, starting with Moderna’s 90-percent-effective formulation, will soon follow.
