About New York State MMR Vaccination Rates
This report is based on data as of January 1, 2026 from the New York State Immunization Information System (NYSIIS). The rates below are calculated based on data of children who have received 1 MMR (Measles, Mumps, Rubella) immunization by 2 years of age, reported their residency as the State of New York, provided their New York State county of residence, and have at least one immunization or have a New York State birth record outside of New York City. According to CDC, children should receive the first dose of MMR vaccine routinely at age 12 through 15 months of age.
Data Notes
- As of January 8, 2008, all health care providers in New York State, outside of New York City, are required to report all immunizations administered to people less than 19 years of age, along with the person's immunization histories, to the Department using NYSIIS.
- Calculated rates are based on where the individual resides, based on the most recent resident information reported through NYSIIS.
- The New York City Department of Health and Mental Hygiene (NYCDOHMH) maintains non-COVID-19 immunization records for New York City residents through the Citywide Immunization Registry (CIR).
- Some entities that are not under the regulatory authority of the State of New York (e.g., federal entities such as federal military facilities, first nations, and jurisdictions outside of New York State), may not report this data to New York State, and would therefore not have their data included in Department rates.
- ZIP codes that straddle more than one county are included in each county's map and table based on the open data page here and in consultation with local county health departments. The rate for the entire ZIP code is shown. The county overall rate includes only those children who report the given county of residence. This can lead to some discrepancies between the ZIP code rates and the county rates in the table below.
- Data are not included for ZIP codes where there are less than 20 residents in the eligible age range.
