After decades of mystery, scientists have uncovered how the NIAID-supported delta inulin vaccine adjuvant works, lowering the hurdle to regulatory approval for vaccine candidates that contain it.

NIAID has funded the discovery and development of the delta inulin adjuvant for many years, currently through a tuberculosis vaccine adjuvant research program.
