Determinants of trust in the flu vaccine for African Americans and Whites

Trust is thought to be a major factor in vaccine decisions, but few studies have empirically tested the role of trust in adult immunization. Utilizing a 2015 national survey of African American and White adults (n = 1630), we explore multiple dimensions of trust related to influenza immunization, including generalized trust, trust in the flu vaccine, and trust in the vaccine production process. We find African Americans report lower trust than Whites across all trust measures. When considering demographic, racial, and ideological predictors, generalized trust shows statistically significant effects on both trust in the flu vaccine and trust in the vaccine process. When controlling for demographic, racial, and ideological variables, higher generalized trust was significantly associated with higher trust in the flu vaccine and the vaccine process. When controlling for generalized trust, in addition to the baseline covariates, psychosocial predictors (i.e. risk perception, social norms, knowledge) are significant predictors of trust in flu vaccine and trust in the vaccine process, with significant differences by race. These findings suggest that trust in vaccination is complex, and that significant differences in trust between White and African American adults may be contributing to disparities in influenza immunization.
