Update: D.C. will receive 13,650 Pfizer coronavirus vaccines (including 8,775 doses from Virginia) and 20,600 Moderna vaccines (including 8,000 doses from Maryland) during the second week of shipments.

Original: Maryland has agreed to provide D.C. with an additional 8,000 COVID-19 vaccine doses, according to a Maryland Health Department letter addressed to DC Health. The news was initially reported by the Washington City Paper.

This is to help vaccinate frontline healthcare workers who work in the District but reside in Maryland.

D.C. was set to receive fewer than 7,000 doses as an initial allotment from the federal government, a number based on overall population. However, this would cover less than a tenth of the city’s 85,000 health care employees, many of which (perhaps as many as 75%) live outside of the District and in Maryland and Virginia.

That means the 8,000 doses that Maryland is giving D.C. is more than what the federal government was set to initially provide the District.

Virginia, too, promised to provide the city with 8,000 doses for front line health care workers.

These additional doses will allow the District to move forward faster on vaccinating its second priority group, long-term care residents.

Since the federal government’s plan was made public last month, D.C. Mayor Muriel Bowser has consistently advocated for the District to receive more doses. This includes a letter she sent earlier this month to Operation Warp Speed asking that the vaccine to be disseminated based on workforce population as opposed to residential population.

Maryland is set to get 155,000 vaccine doses within the next two weeks, provided the Moderna vaccine receives FDA emergency authorization later this week. Of that total, 55,700 doses will be the vaccine made by Pfizer and 104,300 doses will be the Moderna vaccine, the Maryland Health Department tells DCist/WAMU.

The 8,000 doses are expected to be from this allotment, representing only about 5% of Maryland’s initial allotment of doses. The doses are expected to arrive end of this week or early next, according to DC Health. They’ll all be from Moderna, per the Maryland Department of Health.

In both the District and Maryland, frontline health care workers started receiving the vaccine earlier this week.

Tuesday, Maryland Governor Larry Hogan said the state should expect to receive up to 300,00 doses by the end of the month, though Deputy health secretary Dr. Jinlene Chan cautioned that availability from the federal government could change “even on a daily basis.” The Maryland National Guard will also be assisting in the distribution of the vaccine in the state.

The story was updated with information that the doses sent to D.C. will be the Moderna vaccine and when they are expected to arrive.
