The National Health Interview Survey (NHIS) monitors the nation’s health by conducting in-person household interviews on a broad range of health topics, including vaccinations received by adults.


The Behavioral Risk Factor Surveillance System (BRFSS) monitors major behavioral risks among adults at the state level and includes questions on health factors related to vaccinations, including yearly questions on flu and pneumococcal vaccinations and questions related to flu, tetanus, and shingles vaccines on alternating years.


The Pregnancy Risk Assessment Monitoring System (PRAMS) monitors major health issues before, during, and shortly after pregnancy and includes questions about flu and tetanus vaccinations.

Minimum Data Set

The Centers for Medicare & Medicaid Services (CMS) Minimum Data Set provides a screening and assessment tool for the comprehensive assessment of all residents in Medicare and Medicaid-certified long-term care facilities.

Internet Panel Surveys

CDC uses Internet panel surveys to monitor health issues of special populations, including pregnant women and healthcare personnel. Internet panel surveys include questions related to attitudes about vaccination, health factors related to vaccinations, and flu and tetanus vaccinations.
