Pfizer and BioNTech asked the Food and Drug Administration Friday for full approval of the companies’ Covid-19 vaccine. If approved, it would be the first Covid-19 vaccine in the United States to hold that distinction.
The vaccine was the first to be granted an emergency use authorization, or EUA, in December, for use in the U.S.
Vaccines can only be authorized in this manner during public health emergencies — in this case, the Covid-19 pandemic. Indeed, all Covid-19 vaccines currently in use in the U.S. are being administered through EUAs.
