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 SchoolVaxView and the CDC’s National Immunization Survey (NIS). SchoolVaxView is based on questionnaires sent by states to most schools and provides state-level estimates; NIS is based on household survey responses and provides state-level estimates.
SchoolVaxView and National Immunization Survey (NIS) are complementary data sources, and using them together gives a fuller picture of vaccination coverage. Here’s how:
- NIS shows whether children are up to date at ages up to 3 years (well before school entry). SchoolVaxView shows if children are up to date when they reach kindergarten (around age 5).
- NIS data includes data on uptake based on urbanicity (whether children live in a rural area or a small/large city), and by insurance status. This helps identify access- and equity-related gaps that may emerge before school age.
- SchoolVaxView is dependent on accurate reporting of immunization rates by schools to the state. However, this may miss individuals that are outside the school system (such as homeschooled students). In addition, reporting methods vary by state. See SchoolVaxView for more information on data notes and exceptions. NIS may miss individuals who don’t respond to surveys and may overestimate coverage compared to the broader population because they only capture people who respond to surveys.
- States/localities can use NIS to identify at-risk groups before school age, while SchoolVaxView helps ensure school entry requirements are working.
In short: Each dataset has limitations, but together they provide a fuller picture of vaccination coverage in the US. Use NIS to monitor early childhood trends and disparities, and SchoolVaxView to measure coverage at the key checkpoint of school entry.
