It was last updated by the U.S. Department of Health & Human Services in August 2025.

Use Cases

• Analyze state-level trends in MMR or DTaP vaccination coverage to identify regions with declining immunization rates.
• Compare rates of medical and non-medical exemptions across different states to study policy impacts.
• Model the correlation between varicella or polio vaccination coverage and reported exemption rates.
• Assess national trends in hepatitis B immunization among kindergartners over time.
