PORTLAND, Maine (AP) — Gov. Janet Mills said Wednesday the number of doses of the new coronavirus vaccine that the state could receive later this month is disappointingly low.

Mills, a Democrat, said the state is slated to get about 12,600 doses of a vaccine by the middle of December. The vaccine requires two doses, which means the shipment could allow the state to vaccinate some 6,300 people.

The people at the front of the line for the new vaccine would be health care workers. Mills called the number of doses “far less than what is needed.” She said the state hoped for closer to 36,000 doses in the initial shipment.

Maine Center for Disease Control and Prevention Director Dr. Nirav Shah has said the number of vaccine doses the federal government could ship to Maine is a preliminary number that could change.
