U.S. Adult Influenza Vaccination Coverage with Demographic and Temporal Comparisons

Cumulative influenza vaccination coverage data for adults 18 years and older in the United States, collected via the National Immunization Survey-Adult COVID Module (NIS-ACM) launched in April 2021. The dataset includes estimates, confidence intervals, and comparisons across demographic groups and time periods. It was last updated on data.cdc.gov on 2023-04-28.

Use Cases

• Analyze vaccination coverage trends over time using Current_Season, Month, and Current_Week_Ending_Date.
• Compare demographic disparities in vaccination rates using Race_Ethnicity_Sort_Order, Age_Group, and Urbanicity.
• Assess statistical significance of coverage differences using Current_Season_Estimate, Current_Season_95_CI, and Difference_Indicator.
• Model geographic variation in vaccination uptake using Geographic_Level, Parent_Geography_Name, and Geography_Name.

Strengths

• Includes confidence intervals (Current_Season_95_CI) and sample sizes (Weighted_Sample_Size, Unweighted_Sample_Size) for statistical rigor.
• Provides temporal granularity with columns for month (Month), week (Current_Week_Ending_Date), and season (Current_Season).
• Offers multiple data formats (CSV, JSON, XML, RDF) for interoperability.

Limitations

• Row count is unknown, which may limit suitability assessment.
