From the article:
Prashant Yadav, who studies health care supply chains with the Center for Global Development in Washington, said Moderna might be able to “relatively quickly” make more of its vaccine if it received the green light to add doses to each vial.
But he said it would not be an instant change. “I don’t think Moderna has a surplus sitting around,” he said.
Mr. Yadav said the finish-and-fill process is intensely automated, devoted to warding off contamination and precise to the microgram. At top speed, as many as 1,000 vials of vaccine can be filled per minute, he said.
He said a 15-dose vial carries a trade-off: It could lead to more wasted doses if the health care professional runs out of people to get inoculated and has to throw out the rest of the doses. But in the midst of a raging pandemic, experts said, that may well be a risk that federal health officials would be willing to take.
