DC's Vaccination Success Story: How the District Hit 93% MMR Coverage

Four years ago, only 79% of District kindergarteners had received the two doses of MMR vaccine required for school enrollment. Today, that figure stands at 92.7%—matching the national average and representing one of the most significant public health turnarounds in the city's recent history. The improvement came not from a single initiative, but from a sustained, citywide campaign that DC Health launched to close immunization gaps that had left vulnerable populations at risk for outbreaks of vaccine-preventable diseases.

DC Health's strategy centered on removing barriers and building trust. The agency partnered with the Office of the State Superintendent of Education (OSSE), DC Public Schools, charter schools, and community providers to align vaccination efforts around critical school transitions—kindergarten entry at age 5, 7th grade, and 11th grade. Weekly coordination calls ensured consistency across systems, while hands-on training for school staff and real-time family support made navigation of vaccination requirements less burdensome. Mobile health units, urgent care clinics, pharmacies, and school-based clinics expanded vaccine availability across neighborhoods, ensuring families had accessible options regardless of zip code.

But the data also reveals persistent disparities. While kindergarten vaccination rates in public and public charter schools reached 93-94%, private and parochial schools lagged at 81-84%. Ward 2 showed notably lower coverage at 80% compared to the citywide average, and Black and African American children had rates of 84%—highlighting communities where continued outreach remains essential. DC Health strengthened its data infrastructure, including the District of Columbia Immunization Information System (DOCIIS), allowing real-time coordination between schools and providers while tracking coverage by neighborhood and demographic group.

Public messaging campaigns, including robocalls, mailings, and town halls, helped shift perceptions about vaccine safety and necessity. The investments were powered in part by federal pandemic recovery dollars, underscoring how temporary funding can catalyze permanent infrastructure improvements. As measles resurges in parts of the country, DC Health continues working with healthcare providers and families to maintain high coverage and prevent outbreaks. The District's experience offers a template: when local public health is properly resourced and communities are engaged as partners rather than targets, vaccination rates climb.

DC Health remains committed to the full immunization schedule recommended by the American Academy of Pediatrics and the American Academy of Family Physicians—a stance the agency reaffirmed in February when the CDC adjusted its national childhood vaccine recommendations. All vaccines on the District's schedule continue to be covered by public and private insurers at no out-of-pocket cost to families.
