What are the vaccination coverage estimates for my local area?
The NIS estimates vaccination coverage for the 50 states, six urban areas that receive federal immunization grant funding (Chicago, IL; Houston, TX; New York City, NY; Philadelphia, PA; San Antonio, TX; Washington, D.C.), and other selected city and county areas designated by state immunization programs.. Due to sampling methods and sample size constraints of the NIS, coverage for smaller geographical areas can not be estimated.
