Introduction: CDC estimates that influenza resulted in 9–41 million illnesses, 140,000–710,000 hospitalizations, and 12,000–52,000 deaths annually during 2010–2020. Persons from some racial and ethnic minority groups have historically experienced higher rates of severe influenza and had lower influenza vaccination coverage compared with non-Hispanic White (White) persons. This report examines influenza hospitalization and vaccination rates by race and ethnicity during a 12–13-year period (through the 2021–22 influenza season).

Methods: Data from population-based surveillance for laboratory-confirmed influenza-associated hospitalizations in selected states participating in the Influenza-Associated Hospitalization Surveillance Network (FluSurv-NET) from the 2009–10 through 2021–22 influenza seasons (excluding 2020–21) and influenza vaccination coverage data from the Behavioral Risk Factor Surveillance System (BRFSS) from the 2010–11 through 2021–22 influenza seasons were analyzed by race and ethnicity.

Results: From 2009–10 through 2021–22, age-adjusted influenza hospitalization rates (hospitalizations per 100,000 population) were higher among non-Hispanic Black (Black)(rate ratio [RR]= 1.8), American Indian or Alaska Native (AI/AN; RR= 1.3), and Hispanic (RR= 1.2) adults, compared with the rate among White adults. During the 2021–22 season, influenza vaccination coverage was lower among Hispanic (37.9%), AI/AN (40.9%), Black (42.0%), and other/multiple race (42.6%) adults compared with that among White (53.9%) and non-Hispanic Asian (Asian)(54.2%) adults; coverage has been consistently higher …
