Although not all States participate in the HCUP database, the Nationwide Inpatient Sample is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.

Percent of high-risk persons (e.g., COPD) age 18-64 who ever received a pneumococcal vaccination. Percent of persons age 65 and over who received an influenza vaccination in the past 12 months.
