Adult Vaccination Coverage from BRFSS Across U.S. States

Data from the Behavioral Risk Factor Surveillance System (BRFSS) tracks adult vaccination coverage. It provides national, regional, and state-level estimates for the general population aged 18 and over. The dataset includes metrics for vaccines such as Pneumococcal, Zoster, Td, and Tdap.

Use Cases

• Analyze Pneumococcal vaccination coverage disparities across state and age groups.
• Model trends in Zoster (shingles) vaccine uptake at national and regional levels.
• Compare Td and Tdap immunization rates among different adult demographics.
• Assess geographic patterns in vaccination coverage using state-level data.

Strengths

• Data sourced from the authoritative Behavioral Risk Factor Surveillance System (BRFSS).
• Provides geographic granularity with national, regional, and state-level estimates.
• Covers multiple key adult vaccines including Pneumococcal, Zoster, Td, and Tdap.
• Last updated in March 2026, indicating recent data.

Limitations

• Unknown row count and specific column structure limit precise analytical planning.
• Data format includes XML and RDF, which may require specialized parsing tools.
• Coverage is limited to the U.S., with no international comparisons.
