Abstract

challenge. Furthermore, rAd-Rv1471 acted as an effective heterologous booster, enhancing protection in BCG-primed mice. Our findings establish rAd-Rv1471 as a synergistic mucosal vaccine candidate that concurrently induces trained immunity in AMs and polyfunctional T-cell responses, highlighting a promising dual-targeting strategy for next-generation TB vaccines.
