MaineHealth will open its COVID-19 vaccination clinic located at 409 Old County Road in Rockland to walk-in patients on Wednesday, May 5, and will open the Belfast clinic in the former MBNA complex in Belfast to walk-ins on Tuesday, May 4, from 8 a.m. to 3 p.m.

Walk-in slots are limited; they are available on a first-come, first-served basis to any Maine resident 18 and older. Walk-ins should be prepared for the possibility that all slots will have been filled before their arrival.

“Expanding vaccination opportunities is the best way out of the pandemic,” Dr. Cheryl Liechty, an infectious disease specialist at Pen Bay Medical Center, said in a news release. “We want to do everything we can to work toward a return to a more normal life as soon as possible.”

In addition to accepting walk-ins, both clinics will also continue to schedule appointments. To make an appointment, visit mainehealth.org/vaccine or call (877) 780-7545. Those under age 18 must make an appointment to ensure that they are matched to a vaccine that has been approved for their age group.

Both clinic locations follow the guidance of the Maine Center for Disease Control. There is assistance available at both clinics for those wtih mobility concerns. Everyone entering the clinic will be screened for symptoms of COVID-19 and will be required to wear a mask, maintain social distancing and sanitize their hands.

“To date, the two clinics have combined to administer more than 31,000 total doses in Knox and Waldo counties,” Liechty said.
