People can get the Johnson & Johnson vaccine without an appointment on Sunday at a mobile clinic in Biddeford, the Maine Center for Disease Control and Prevention announced Saturday night.

Maine residents age 18 or over can get the single-dose coronavirus vaccine from 8:30 a.m. to 3:30 p.m. at the mobile vaccination clinic at Biddeford High School at 20 Maplewood Ave.

“Sunday’s no-appointment availability of the Johnson & Johnson vaccine provides an opportunity for Maine people who prefer a one-shot vaccine to get vaccinated on the weekend and without the need to schedule in advance,” Dr. Nirav Shah, director of the Maine CDC, said in a statement. “This is part of our ongoing effort to expand vaccination options for Maine people.”

A spokesman for the Federal Emergency Management Agency, which opened the Biddeford clinic, said Saturday night that the mobile vaccination clinic at the high school will also be open from 8:30 a.m. to 4:30 p.m. on Monday, Tuesday and Wednesday, and that Maine residents age 18 and older can get the Johnson & Johnson vaccine without an appointment.

Maine resumed use of the J&J vaccine after the U.S. Centers for Disease Control and Prevention and the Food and Drug Administration on Friday evening announced the lifting of an 11-day pause on the use of the vaccine after an expert panel reviewed scientific information about extremely rare blot clots that a small number of patients experienced after receiving the vaccine.

The mobile vaccination clinic, which had switched to the Moderna vaccine during the pause, has resumed offering the one-dose Johnson & Johnson vaccine at its location in Biddeford.

Individuals who receive the J&J vaccine are considered fully vaccinated 14 days after getting their shots.
