The National Immunization Survey (NIS) is a set of national surveys conducted annually by Centers for Disease Control and Prevention to assess immunization levels. The NIS-Child assesses immunization coverage among preschool children at 24 months of age. The NIS-Teen assesses immunization levels for adolescents 13-17 years of age. The NIS is the only population-based survey to provide national, state, local area, and territorial estimates of vaccination coverage among preschool-aged children and adolescents 13-17 years in the United States.

The NIS-Flu assesses influenza immunization coverage levels annually by combining data from other surveys including other NIS modules and the Behavioral Risk Factor Surveillance System (BRFSS). The NIS-Flu provides national, state, local area, and territorial estimates of influenza vaccination coverage among children and adults in the United States.
