Moderna announced early Monday that its experimental coronavirus vaccine was 94.5% effective at protecting people from the novel illness.
Following Pfizer Inc.’s announcement last week that its vaccine candidate was testing at rates of 90% efficacy, Moderna’s vaccine becomes the second prospective vaccine that could be available to a limited portion of the American populous by year’s end.
“It’s extremely good news. If you look at the data, the numbers speak for themselves,” said Dr. Anthony Fauci, the director of the National Institutes of Allergy and Infectious Disease and the public face of the government’s coronavirus response effort. “I said certainly a 90-plus-percent effective vaccine is possible, but I wasn’t counting on it.”
