D.C. will open a “high-capacity” vaccination site at Arena Stage this week, D.C. Mayor Muriel Bowser announced on Monday.

Starting on Friday, Arena Stage, in partnership with DC Health and Medstar Health, will launch a large-scale vaccination site for eligible District residents. The site will operate Thursdays through Sundays, from 9 a.m. to 5 p.m, and mark the first and only high capacity site located in Southwest D.C.

DC Health did not immediately return DCist’s request for comment on how many people will be vaccinated at the site each day, but the city’s first three high capacity sites at the Walter E. Washington Convention Center in Northwest, the Entertainment and Sports Arena in Southeast, and Providence Health Systems in Northeast vaccinated more than 700 people, each, on their first days of operation.

“Arena Stage is so happy to be asked to play this role for our community,” Arena Stage executive producer Edgar Dobie said in a press release about the new location. “We can promise everyone a warm and gracious greeting as these essential vaccines are administered by the talented folks at MedStar Health.”

Like the other three large-scale sites, the new Arena Stage location will likely offer the one-shot Johnson and Johnson vaccine, DC Health director LaQuandra Nesbitt said during a Monday press conference. Bowser also announced that a new Safeway partnership will boost supply at the Convention Center starting this week. According to Nesbitt, the additional doses coming to the convention center will likely be Pfizer vaccines, and appointment invitations will be sent out this Tuesday.

Appointments for the Arena Stage site, and all other high-capacity sites, are allocated through the city’s pre-registration system, which sends out notification of available appointments on Thursdays and Sundays. Remaining appointments for the week that have not been filled go out on Tuesdays. Currently, D.C. residents over age 16 with a qualifying medical condition, all residents over ages 65 and older, and residents that fall into a slew of essential worker categories are eligible to book a vaccine appointment at one of the high-capacity sites. The city plans to expand eligibility to all residents starting May 1.

The fourth mass vaccination site comes as the city continues to stress the need for more supply from the federal government. Last month Chris Rodriguez, the director of the city’s Homeland Security and Emergency Management Agency, said that D.C. had the personnel capacity to open more high-capacity sites, but lacked the necessary doses from the federal government.

While the Federal Emergency Management Agency has offered to help D.C. with the logistics of operating such sites, the agency denied building out a federally-supported mass vaccination site in D.C., which would use additional doses beyond D.C.’s allotments. One such FEMA-supported mass vaccination clinic is opening in Greenbelt, Md. this week — and is allowing D.C. residents ages 16 and older to pre-register for a vaccination there.

As of April 5, 23% of D.C. residents have received at least one dose of a vaccine — but disparities remain. Only 8% and 9% of Ward 8 and Ward 7 residents, respectively, are partially or fully vaccinated, compared to nearly double those percentages in the city’s wealthier, whiter, wards 3 and 4. Over the weekend, several nonprofit and community organizations partnered to stand up a vaccination site specifically for Ward 8 residents over age 16, with the goal of distributing 1,000 Johnson & Johnson vaccines in a day.

Arena Stage, meanwhile, first closed March 16, 2020, at the beginning of the coronavirus pandemic. The 200,000-square-foot campus has not hosted performances since last spring, though the creative team has produced films and virtual theater chats during the shutdown. (Also in her Monday press conference, Bowser announced that live entertainment venues could reopen to guests at 25% capacity, indoors or outdoors, starting on May 1.)
