ANNAPOLIS, Md. — Maryland is authorizing COVID-19 booster shots for all residents 65 and older who live in congregate care settings.

Gov. Larry Hogan says residents in nursing homes, assisted-living facilities, residential drug treatment centers and developmentally disabled group homes are eligible.

Hogan told a news conference Wednesday that “boosters can now be immediately administered.”

While the federal government has yet to say when most people should get booster shots, Hogan said the U.S. Centers for Disease Control and Prevention has approved them for people who are immunocompromised, and a Maryland study indicates many in those facilities are immunocompromised.

He said the state is “following CDC guidance but broadening the definition.”
