How to use this data
These plots show estimates of childhood immunization rates, broken down by state, age, urban vs. rural residence, and insurance status. You can choose which vaccine and age group to view. The data come from two sources: the CDC’s National Immunization Survey (NIS) and Epic Cosmos. NIS is based on household survey responses and provides state-level estimates. Epic Cosmos reflects data from children who have had recent primary care visits at facilities using Epic’s electronic health record system.
Each dataset has its limitations. NIS may miss individuals who don’t respond to surveys, while Epic Cosmos only includes those regularly accessing care at specific health systems. Because of this, both sources may overestimate vaccine coverage compared to the broader population. Triangulating between them helps provide a clearer picture.
