Weekly Adult COVID-19 Vaccination Coverage by Jurisdiction and Season

Weekly estimates from 2023-24 to 2025-26 seasons track COVID-19 vaccination coverage and intent among adults 18 years and older. The data is produced by the CDC using the National Immunization Surveys-Fall Respiratory Virus Module, a random-digit-dial cellular telephone survey. It provides jurisdiction-level comparisons of current and past season vaccination rates.

Use Cases

• Analyze weekly vaccination coverage trends (Curr_est) across different jurisdictions (Geography_name) and demographic groups (Demographic_Level).
• Compare vaccination coverage between the 2025-26 season (Curr_season) and previous seasons (Past_season) using the Difference_estimate column.
• Assess the statistical significance (Significance) of observed differences in vaccination rates between seasons.
• Model the relationship between demographic factors (Demographic_Name, Demographic_Level) and vaccination intent or coverage.
• Visualize geographic disparities in vaccination coverage (Geography_name) over time using weekly ending dates (Current_season_Week_Ending, past_week_ending).

Strengths

• Provides weekly temporal granularity for tracking vaccination dynamics.
• Includes confidence intervals (Curr_CI_95, Past_CI_95) for statistical reliability of estimates.
• Enables direct season-over-season comparisons (2023-24, 2024-25, 2025-26) through dedicated columns.

Limitations

• All vaccination data is self-reported, which may introduce recall or social desirability bias.
• Sample sizes and row counts are unknown, limiting assessment of statistical power for smaller jurisdictions or demographics.
• Comparisons between seasons require careful interpretation due to differing vaccine availability dates, as noted in the description.
