Maryland’s new coronavirus vaccination data portal provides glimpse into early vaccination efforts

With the rollout of Moderna and Pfizer’s COVID-19 vaccines in Maryland to nursing homes and front-line health care workers beginning in recent days, Maryland has launched a new data portal on coronavirus vaccinations.

According to the data as of Wednesday afternoon, 10,497 people in the state have been administered vaccines. That means 0.17% of the state has been vaccinated, according to the state’s data.


Maryland is in the very early stages of its vaccination distribution plan, with some of its first vaccinations coming early last week. More than 100,000 doses of Moderna’s vaccine began coming to Maryland this week, bringing the state to 191,075 doses of Pfizer and Moderna vaccines, enough to vaccinate 90% of the state’s front-line health care workers. Maryland health care workers began receiving some of the first doses statewide of Pfizer’s vaccine last week.

Maryland is in Phase 1A of its vaccine distribution. Health care workers and long-term care facility residents and staff are at the front of the line for vaccines. The Pfizer and Moderna vaccines have both shown better than 94% efficacy.


The Baltimore metropolitan area — which the state defines as Anne Arundel, Baltimore, Carroll, Harford and Howard counties as well as Baltimore City — has seen the most vaccinations so far, with 6,322 vaccines given. That means 0.23% of the region’s population has been vaccinated.

The “National Capital” area — which comprises Charles, Frederick, Montgomery and Prince George’s County — has seen 1,509 people vaccinated, or 0.06% of the population. Western Maryland (Allegany, Garrett and Washington counties)has seen 451 people vaccinated, or 0.18% of those counties’ populations.

With 1,325 vaccinations, Maryland’s Eastern Shore has seen the highest percentage of its population vaccinated at 0.29%. Southern Maryland (Calvert and St. Mary’s counties) has seen 75 people vaccinated, the lowest population share vaccinated among the state’s regions at 0.04%.

The state’s data, which can be found at, also tracks the number of vaccines given by race, age, gender and ethnicity.

Through Wednesday’s early data, about 66% of people vaccinated have been women, and 69% have been white and 11% have been black. About 3% of people vaccinated have been Hispanic or Latino, and about 9% have been Asian.
