Each year in the United States, influenza (flu) results in more than 200,000 hospitalizations and 36,000 deaths, many of which are avoidable with a proper vaccination. To estimate flu vaccination coverage for the 2016-2017 flu season, the CDC assessed data from the National Immunization Survey-Flu (NIS-Flu) for children aged six months through 17 years, and the Behavioral Risk Factor Surveillance System (BRFSS) for adults 18 and older. During this period, the influenza vaccination rate nationally was 46.8%; by state, Rhode Island (55.4%) had the highest vaccination rate, and Nevada had the lowest (36.1%). Specifically, the cohort that represents the greatest opportunity for improvement in Nevada is children aged six months to four years, given that the Nevada vaccination rate among this population (44.0%) was nearly 16 percentage points lower than the national benchmark (59.9%).

Flu vaccination coverage is estimated from two surveys, Behavioral Risk Factor Surveillance System (BRFSS; current as of September 2017) and National Immunization Survey-Flu (NIS-Flu; current as of October 2017), and cover July 2016 through May 2017.
