Childhood Vaccination Data Explorer
The data below show estimates of vaccination coverage (the percentage of people who are vaccinated) in New York City for children ages 6 months to 17 years, by vaccine type.
It includes trends over time and breakdowns by race and ethnicity, borough, and ZIP Code. The data can be downloaded from our GitHub repository.
Vaccines prevent disease and reduce the risk of hospitalization, health complications, and death. The higher the vaccine coverage in a community, the lower the risk that a vaccine-preventable disease will spread if the disease enters the community.
The data come from the NYC Health Department's Citywide Immunization Registry (CIR). The CIR keeps immunization records for NYC residents — children and adults — throughout their lifespan and has records for non-NYC residents vaccinated in the city. Vaccinations given to people ages 18 and younger are required to be reported to CIR. People can access CIR records for themselves and their children by visiting My Vaccine Record.

How Vaccine Coverage is Calculated
Coverage is calculated by dividing the number of vaccinated NYC residents (numerator) by the total population estimate (denominator), then multiplying by 100 to get a percentage.
How do we know the number of people who have been vaccinated?
When children are vaccinated in NYC, their records are reported to the NYC Health Department’s Citywide Immunization Registry (CIR). Healthcare providers in NYC can also enter their patients’ prior vaccination records into CIR, for example when someone moves to NYC.
How do we know the total population?
We use population estimates from the NYC Health Department, based on data from the U.S. Census Bureau and the NYC Department of City Planning. The NYC population is constantly changing, due to births, deaths, and people moving in and out of the city. For this reason, population estimates are updated regularly to best reflect who lived in the city at a given point in time.
Why do past coverage calculations change?
As population estimates are updated, we revise past vaccination coverage to ensure it reflects the most current, reliable information available. This means the coverage you see now may differ from coverage previously provided on this webpage and published elsewhere.
For more details, visit our GitHub page.
Data Update Schedule
The data on this page will be updated twice each year. Vaccination coverage is assessed as of June 30 and December 31 each year, and data is released a few months later. When new population estimates are released, vaccination coverage is adjusted accordingly using the same numerators and the new population estimates. Vaccination coverage using previous population estimates are then archived.
Note: Last updated on March 6, 2026 with data through December 31, 2025. Data for 2020-2025 were also revised to incorporate updated population estimates for this time period.Suggested Citation
