The Moderna vaccine is 94.5% effective against coronavirus, according to early data released Monday by the company, making it the second vaccine in the United States to have a stunningly high success rate.
"These are obviously very exciting results," said Dr. Anthony Fauci, the nation's top infectious disease doctor. "It's just as good as it gets -- 94.5% is truly outstanding."
Moderna heard its results on a call Sunday afternoon with members of the Data Safety and Monitoring Board, an independent panel analyzing Moderna's clinical trial data.
"It was one of the greatest moments in my life and my career. It is absolutely amazing to be able to develop this vaccine and see the ability to prevent symptomatic disease with such high efficacy," said Dr. Tal Zacks, Moderna's chief medical officer.
Vaccinations could begin in the second half of December, Fauci said. Vaccinations are expected to begin with high-risk groups and to be available for the rest of the population next spring.
