Weekly Cumulative Influenza Vaccinations in US Pharmacies and Medical Offices

IQVIA-sourced data estimates 92% of national influenza vaccinations in retail pharmacies and 82% in physician medical offices for adults 18 years and older. Weekly cumulative counts are provided by setting (pharmacy or medical office), influenza season, and MMWR week. The dataset supports tracking vaccination campaign progress and coverage disparities across different healthcare delivery settings.

Use Cases

• Tracking weekly vaccination progress by setting (Setting) and influenza season (Influenza_Season).
• Analyzing cumulative vaccination trends over time using MMWR_Week and Cumulative_Doses.
• Comparing vaccination volumes between pharmacy and medical office settings using the Doses column.
• Aligning vaccination data with public health reporting calendars using Week_ID and Current_Season_Week_Ending_Label.

Strengths

• Data coverage is high, with sampled pharmacies representing approximately 92% of national influenza vaccinations and medical offices representing 82%.
• Provides weekly granularity (MMWR_Week) for tracking vaccination campaign progress in near real-time.
• Cross-platform presence on Socrata and Dataverse indicates established use and importance for public health data sharing.

Limitations

• Metadata conflicts exist: the author is listed as 'United States Department of Health and Human Services. Centers for Disease Control and Prevention' on some platforms and 'None' on others.
• Excludes vaccinations administered in other settings such as workplaces and community clinics.
• Key metadata like row count, dataset size, and explicit license information is missing from all provided sources.
