About the National Immunization Survey (NIS-Flu)

The NIS-Flu combines flu vaccination responses collected from annual surveys conducted by the Centers for Disease Control and Prevention (CDC) including the NIS-Child, NIS-Teen, NIS-Childhood Influenza Module (NIS-CIM), and the Behavioral Risk Factor Surveillance System (BRFSS) for all age groups (Figure 1). NIS-Flu data are used to estimate annual flu vaccination coverage among children 6 months-17 years and adults 18 years and older at the national level, state level, selected local levels, and in some U.S. territories. These NIS-Flu estimates are based solely on parent or guardian reported data (for children) and self-reported data (for adults), in contrast to other modules of the NIS which are verified by provider data. The NIS-Flu also provides fewer local area estimates than the NIS-Child and NIS-Teen. The 2017-2018 survey assessed the self-reported immunization status of approximately 436,000 children and adults in the United States. The Texas sample consisted of 18,715 respondents.
