Fauci spoke after Pfizer Inc. and BioNTech SE reported earlier this week that the vaccine they’re developing is more than 90% effective, according to preliminary results of a broad study. Findings from the trial of a similar shot, developed by Moderna Inc., are expected soon.
Covid won’t be a pandemic for “a lot longer” thanks to rapid progress in vaccine development, according to Anthony Fauci, the top U.S. infectious disease official.
The coronavirus could nonetheless circulate for years, and people need to recommit to inexpensive public health measures like wearing masks, washing hands and social distancing as cases surge, the director of the U.S. National Institute of Allergy and Infectious Diseases said at an event organized by Chatham House, a U.K. think tank.
