CAMBRIDGE (CBS/AP) – The Food and Drug Administration has authorized two changes to Moderna’s COVID-19 vaccine that can provide extra doses from each vial.

The FDA has approved new vials from the Cambridge company that can contain up to 15 doses each, compared with the original vials designed to hold 10 doses. Additionally, regulators said providers can safely extract up to 11 doses from the original 10-dose vials. Those changes will be added to instructions for health care workers.
