Operation Warp Speed leader says he expects coronavirus vaccine to be highly effective, 'in the 90%' range (cnn.com)
(CNN) The head of the government's effort to develop a vaccine against Covid-19 says he expects the vaccine to have efficacy rates "in the 90%" range -- but that there might not be enough vaccine available for all Americans until the end of next year.
"I think it will be a very effective vaccine. That's my prediction," said Moncef Slaoui, chief adviser of Operation Warp Speed. "My personal opinion based on my experience and the biology of this virus, I think this vaccine is going to be highly efficacious. I wouldn't be surprised if it's in the 90% [range]."
