Every year, millions of Americans receive a flu vaccine (also commonly called a “flu shot”) to protect against strains of the influenza virus during flu season, which typically lasts from October to May. While not mandatory for many Americans, the flu shot can be a life-saving vaccine for people at higher risk of severe complications from influenza, such as adults age 65 and older and individuals with chronic health conditions or diseases (e.g., asthma, diabetes, cancer). Tracking flu vaccination rates in the United States can help detect gaps in vaccination coverage across different demographic groups and identify populations that are under-vaccinated against influenza.
State Health Compare provides state-level data on adult flu vaccination rates, which can be broken down by nine sub-categories: age group, chronic disease status, type of insurance, education level, household income, metropolitan status, personal doctor status, race/ethnicity, and sex. The data are based on public use files from the Behavioral Risk Factor Surveillance System (BRFSS) survey.
