Childhood Vaccination Coverage Estimates Across U.S. Jurisdictions

National Immunization Survey-Child data provides vaccination coverage estimates for children aged 0-35 months across national, regional, state, and selected local areas. Estimates are organized by birth year and birth year cohorts. The U.S. Department of Health & Human Services maintains this data, which was last updated in April 2026.

Use Cases

• Analyze state-level disparities in DTaP vaccination coverage by birth year cohort.
• Track national trends for MMR vaccine uptake over time using birth year estimates.
• Compare regional Hepatitis B vaccination rates against national benchmarks.
• Model local area coverage for Rotavirus vaccine based on demographic and geographic factors.
• Assess Polio and Varicella immunization progress across different birth cohorts.

Strengths

• Coverage estimates span national, regional, state, and selected local area levels.
• Data includes multiple birth year cohorts for longitudinal analysis.
• Managed by the authoritative U.S. Department of Health & Human Services.

Limitations

• Specific row counts, column names, and sample sizes are not provided.
• Geographic detail may be inconsistent across all local areas.
