The National Immunization Survey-Flu (NIS-Flu) data are used to assess annual flu vaccination coverage among children 6 months-17 years at the national level, state level, selected local levels, and some in U.S. territories.
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 flu 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 vaccinations and questions related to place of flu vaccination every third year.
The Pregnancy Risk Assessment Monitoring System (PRAMS) monitors major health issues before, during, and shortly after pregnancy and includes questions about flu 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 vaccinations.
This is an online probability-based survey of adult members ages 18 or older of KnowledgePanel, an online panel recruited using address-based sampling methodology and representative of the adult U.S. population.
Online survey of adult members of the NORC AmeriSpeak Panel, an online panel representative of the entire U.S. population. The AmeriSpeak panel uses area probability sampling and includes additional coverage of hard-to-survey population segments such as rural and low-income households that are underrepresented in surveys relying on address-based sampling.
