Adult Vaccination Coverage Estimates By State And Year

Estimate (%) data from the Behavioral Risk Factor Surveillance System tracks adult immunization rates for vaccines like Pneumococcal, Tdap, and Shingles. Coverage metrics are provided at national, regional, and state levels, broken down by age groups and other dimensions. The data is published by data.cdc.gov and was last updated in March 2026.

Use Cases

• Analyze trends in Vaccine coverage by Survey Year and Geography to identify areas with declining immunization rates.
• Compare Estimate (%) and 95% CI (%) for different Dose recommendations (e.g., Pneumococcal vs. Shingles) across age-based Dimension groups.
• Assess geographic disparities by joining on FIPS codes to map vaccination coverage by state or region.
• Evaluate survey representativeness by examining Sample Size across different Geography and Dimension Type combinations.

Strengths

• Data includes multiple geographic levels (national, regional, state) via the Geography column.
• Provides confidence intervals (95% CI (%)) for each coverage estimate.
• Covers multiple Vaccine types including Pneumococcal, Td, Tdap, and Shingles.

Limitations

• Sample Size and row count are unknown, limiting assessment of statistical power.
• Specific temporal coverage (Survey Year range) is not provided in the input.
