Weekly Cumulative COVID-19 Vaccination Estimates for Adults by Age Group and Setting

Weekly cumulative estimates of COVID-19 vaccine doses administered to adults aged 18 and older in U.S. retail pharmacies and physician medical offices, segmented by age group and season. The data is sourced from IQVIA's Longitudinal Prescription Claims and Medical Claims, provided by data.cdc.gov, and was last updated in March 2026. It covers multiple COVID-19 vaccination seasons, with the 2023-24 season starting in mid-September 2023.

Use Cases

• Analyze trends in Cumulative_Doses by Age_Group and Setting (e.g., 'Retail Pharmacy') across different COVID-19_Season values.
• Compare weekly vaccination progress using MMWR_Week and MMWR_Year to assess rollout speed between seasons.
• Model the relationship between Doses administered per week and the Week_ID or MMWR_Day for forecasting supply needs.
• Assess demographic coverage by calculating the proportion of total doses administered to specific Age_Group categories like '18-49 years'.

Strengths

• Provides weekly granularity (MMWR_Week) for tracking temporal dynamics.
• Contains data for multiple COVID-19 vaccination seasons, enabling seasonal comparison.
• Disaggregates estimates by two key healthcare settings (Setting) and multiple Age_Group categories.

Limitations

• Excludes vaccinations from workplaces, community locations, and long-term care settings, creating an incomplete picture of total administration.
• Estimates are projections based on claims data, not direct counts, which may introduce measurement error.
• The specific row count and sample size underlying the estimates are unknown.
