"Our plan is to be able to ship vaccines to the immunization sites within 24 hours of approval" by the US Food and Drug Administration, Moncef Slaoui told CNN.

"So I expect maybe on Day Two of the approval, on the 11th or the 12th of December."

FDA vaccine advisors reportedly will meet December 8 to 10 to discuss approving vaccines which Pfizer and Moderna say are at least 95 percent effective.
