Background: Racial/ethnic differences in adult vaccination have been documented, yet the determinants of low coverage among minority groups remain poorly understood.
Objectives: To quantify racial/ethnic disparities in adult influenza vaccination in the United States and to explain the underlying factors that account for these differences.
Methods: The 1998 National Health Interview Survey was analyzed to examine vaccination coverage rates by race/ethnicity for 3 high risk groups: adults 18 to 64 years old with chronic conditions (ACC), adults 65 years and older (elderly), and health care workers (HCW). Andersen’s Behavioral Model was used as a framework to model access to care indicators. Logistic regression was used to assess the relationship between access to care and vaccine coverage. Analyses were conducted in SUDAAN to account for the complex survey design.
Results: Significant racial/ethnic disparities were observed in vaccination coverage for elderly and HCW groups but not for the ACC group. Access to care explains much of disparity between Hispanics and Whites, in particular, predisposing and enabling health care access factors were important determinants. These factors were not related to disparities between Whites and Blacks.
Conclusions: The determinants of vaccination coverage differ by racial/ethnic groups. Further studies are needed to fully explain these disparities, particularly among Blacks. Effective strategies to increase vaccination coverage and decrease the racial/ethnic disparity should be targeted differently to each of these minority groups.
