PORTLAND, Maine (AP) Residents of long-term care facilities in Maine are scheduled to begin receiving the new coronavirus vaccine on Monday.

The Maine Center for Disease Control and Prevention has said more than 4,400 people have been administered the vaccine in the state. However, the state has focused on front-line health care workers until now.

The Moderna vaccine was rolled out in Maine Monday. The first doses are going to hospitals and health care facilities around the state. It follows last week’s rollout of the Pfizer vaccine.

Maine is perennially among the states with the highest median age, and public health authorities have said the effort to vaccinate nursing home residents is a key piece of the state’s fight against the virus.
