New York City Health Department Launches Childhood Vaccination Data Explorer

The Data Explorer Provides Detailed Vaccination Data for NYC Children — Revealing Gaps and Inequities Across the City

June 23, 2025 — Today, the New York City Health Department (NYC Health Department) launched the NYC Childhood Vaccination Data Explorer. The new data visualizations show the percentage of NYC children who are vaccinated for certain recommended vaccines and breaks down the data by race and ethnicity, borough, and ZIP code. The NYC Health Department uses vaccination coverage data to identify inequities that guide programming, including community and provider education and outreach.

“Vaccines are one of the greatest achievements in public health history,” said Acting Health Commissioner Dr. Michelle Morse. “Before vaccines, infectious diseases were the most common cause of death and disability in the United States. The NYC Health Department’s work is grounded in science and equity. We are committed to providing New Yorkers with accurate, evidence-based information to help them make decisions about life-saving vaccinations.”

High vaccination coverage protects our communities, including children too young to be vaccinated and people who have compromised immune systems. We urge parents to talk to their children’s health care provider to stay informed about vaccines and ensure their children have all the vaccines they need to stay protected. This new resource aims to empower health care providers, community partners, public health advocates, and New Yorkers to protect all communities from vaccine-preventable diseases. The Health Department will update the data explorer twice a year and include data for the following vaccines and age groups:

• Combined 7-vaccine series (a summary measure to assess overall coverage that includes 7 separate vaccines: DTaP, Poliovirus, MMR, Hib, HepB, Varicella, and PCV): 2-year-olds
• DTaP (diphtheria, tetanus, acellular pertussis): 2-year-olds
• Poliovirus (polio): 2-year-olds
• MMR (measles, mumps, rubella): 2-year-olds
• Hib (Haemophilus influenzae type b): 2-year-olds
• HepB (hepatitis B): 2-year-olds
• Varicella (chickenpox): 2-year-olds
• PCV (Pneumococcus): 2-year-olds
• HPV (human papillomavirus): 13- to 17-year-olds
• Flu (influenza): 6-month- to 17-year-olds

NYC's childhood vaccination coverage data show striking differences by neighborhood, race and ethnicity, and vaccine type. As of December 31, 2024, only 65 percent of 2-year-olds had received all recommended doses of 7 childhood vaccines, called the combined 7-vaccine series, by their 2nd birthday. For the combined 7-vaccine series, coverage ranged from 53 percent in Staten Island to 73 percent in Manhattan and Queens. Asian non-Hispanic children had the highest vaccination coverage at 92 percent, while white non-Hispanic children had the lowest at 49 percent.

Overall vaccination coverage for MMR among two-year-olds has increased from 88 percent in 2022 to 95 percent in 2024, though geographical differences persist, with coverage in some ZIP codes as low as 54 percent. Outbreaks of vaccine-preventable diseases, including measles, mumps, and pertussis, still occur in the United States and globally. If an exposure to these diseases occurs in a community with lower vaccination coverage, there is an increased risk of disease spreading in that community.

All children must receive certain vaccinations, including DTaP, Poliovirus, MMR, Varicella, HepB, Hib, PCV, and Flu, to attend school, day care, and summer camp in NYC. Families should speak with their child’s pediatrician on necessary vaccinations before any summer travel, which may include early or extra doses of a vaccine. Health care providers should discuss with parents the importance of vaccinating their child on time to ensure the best protection against serious preventable illness.

Talk to your child’s doctor about recommended vaccines. Most primary care providers offer childhood vaccines at low to no cost, including NYC Health and Hospitals. The NYC Health Department Immunization Clinic also offers low to no cost vaccination for people ages 4 years and older.

The information in the Childhood Vaccination Data Explorer comes from the NYC Health Department’s Citywide Immunization Registry, which contains immunization records for NYC residents, including all children ages 18 and younger vaccinated in NYC. While the webpage features data from the last 5 years, data since 2017 are available for download here. New Yorkers can access individual vaccine records for themselves and their children at My Vaccine Record.
