Elfreda Buffong had tried to get a booster shot for Covid-19 at a pharmacy chain only to be told it wasn’t currently available. But on Tuesday morning, the 63-year-old Dorchester resident was able to get her third dose of the BioNTech, Pfizer vaccine, thanks to the “Family Vaccination Clinic” at the Codman Square Health Center.

“I’m just hoping that people will take the vaccine,” she said. “It just makes me feel safe.”

After getting her shot, Buffong was escorted to a nearby waiting room and told about the health center’s vaccination incentives — a free boxed lunch and a chance to enter a lottery for prizes that include Apple Airpods, MacBook Pro, and $500 Visa gift cards.

The Tuesday clinic (with a second scheduled for next Tuesday (Dec. 28), was part of an effort by some of Boston’s community health centers and the Boston Public Health Commission to increase protection from the virus and the expected onslaught of the highly contagious Omicron variant.

“Our family vaccine clinics are another way Codman can care for our community. People are scared, and for good reason. Omicron is rising and hospitals are filling,” said Dr. Renee Crichlow, the health center’s chief medical officer.

“In this season of love, the best gift you can give your family, your community, and yourself is to protect them against serious Covid,” Crichlow added. “We know that vaccines protect against serious infection. Masking and vaccines spread love and stop the spread of serious illness.”

The health center also provides community testing at the Russell Auditorium, at 70 Talbot Avenue. Walk-ins are accepted, but appointments are recommended to save time. For an appointment, call 617 822-8271.

The center has appointment information on its website at codman.org/blog/come-on-down-to-the- covid-19-family-vaccine-clinic.
