WASHINGTON, Nov. 30 (CNA) - The first two vaccines against the COVID-19 could be available to Americans before Christmas, Health Secretary Alex Azar said on Monday (Nov 30), after Moderna became the second vaccine maker likely to receive US emergency authorisation.

The Food and Drug Administration's outside advisers will meet on Dec 10 to consider authorising Pfizer's COVID-19 vaccine. That vaccine could be approved and shipped within days, with Moderna's following one week behind that, Azar said.

"So we could be seeing both of these vaccines out and getting into people's arms before Christmas," Azar said on CBS' This Morning programme.

The federal government will ship the vaccines through its normal vaccine distribution system, with state governors determining where they should go first, Azar said.

"They will be determining which groups to be prioritised. I would hope that the science and the evidence will be clear enough that our governors will follow the recommendations that we will make to them," Azar said.

He said he and Vice President Mike Pence will speak to all the nation's governors later on Monday to discuss the vaccines and which groups of people should be prioritised to get them first.
