Late Friday, the F.D.A. approved the Moderna vaccine, meaning that millions of doses will soon be available. This is the second vaccine to be approved, following the Pfizer one.
Dr. Anthony S. Fauci, the nation’s top infectious disease expert, called the advent of two vaccines “an historic moment.”
“This to me is a triumph of multiyear investment in biomedical research that culminated in something that was not only done in record time, in the sense of never before has anybody even imagined you would get vaccines to people in less than a year from the time that the sequence was made known,” Dr. Fauci said.
Shipments could begin as soon as next week.
