Fauci made the comments on a conference call Monday morning.

“The results of this trial are truly striking,” he said.

“I said I would be satisfied with a 70-75% efficacy and that something like a 95% was very aspirational. Well our aspirations have been met and that is very good news,” Fauci added.

Pfizer reported last week that its vaccine was more than 90% effective.

“It is absolutely unprecedented to have two vaccines with highly promising data from Phase 3 trials less than a year after the global emergence of a novel pathogen,” said Sec. of Health and Human Services Alex Azar.

President Donald Trump tweeted following Moderna’s announcement.

In a pair of tweets, president-elect Joe Biden said that Moderna’s results provide “further reason to feel hopeful,” but added “we are still months away. Until then, Americans need to continue to practice social-distancing and mask-wearing to get the virus under control.”
