Moderna proposes filling vials with additional doses of COVID-19 vaccine

“The company is proposing filling vials with additional doses of vaccine, up to 15 doses versus the current 10 doses,” Moderna said in an emailed statement.

“Moderna would need to have further discussions with the FDA to assure the agency’s comfort with this approach before implementing,” the company said, referring to the U.S. Food and Drug Administration.

Moderna’s president, Stephen Hoge, said in the statement that the additional doses would help address capacity constraints, noting that “beyond the amount of drug product available, is how many vials you can fill in a given period of time.”

CNBC reported on Friday that Moderna had asked the FDA for permission to fill its COVID-19 vaccine vials with up to five additional doses.
