COVID-19 Vaccination Coverage, Overall and by Selected Demographics and Jurisdiction, Amon

Weekly estimates of COVID-19 vaccination coverage and intent among adults 18 years and older are calculated using data from the National Immunization Surveys (NIS)-Fall Respiratory Virus Module. The data includes coverage by demographic characteristics and jurisdiction for the 2023–24, 2024–25, and 2025–26 seasons. It is sourced from data.cdc.gov and was last updated on March 4, 2026.

Use Cases

• Analyze vaccination trends over time using Month_Week, Week_ending, and COVID_season columns.
• Compare vaccination coverage across demographic groups using Demographic Name and Demographic Level columns.
• Assess geographic variation in vaccination rates using Geographic Name and Geographic Level columns.
• Evaluate statistical reliability of estimates using Unweighted Sample Size and CI_Half_width_95pct columns.
• Track specific vaccine uptake by season using the Vaccine and indicator_label columns.

Strengths

• Data is sourced from the CDC's National Immunization Surveys, a recognized public health surveillance tool.
• Includes multiple seasons (2023–24, 2024–25, 2025–26) for longitudinal comparison.
• Provides granular weekly estimates (Month_Week) and demographic breakdowns (Demographic Level, Demographic Name).
• Contains statistical quality indicators like CI_Half_width_95pct and suppression_flag.

Limitations

• All estimates are based on self-reported vaccination data, which may be subject to recall or social desirability bias.
• Row count and total sample size are unknown, which may limit suitability assessment for large-scale modeling.
• Data lags a few days behind the primary CDC Respiratory Illnesses Data Channel due to review processes.
