Overcoming envelope metastability is crucial to trimer-based HIV-1 vaccine design. Here, we present a coherent vaccine strategy by minimizing metastability. For 10 strains across five clades, we demonstrate that the gp41 ectodomain (gp41<sub>ECTO</sub>) is the main source of envelope metastability by replacing wild-type gp41<sub>ECTO</sub> with BG505 gp41<sub>ECTO</sub> of the uncleaved prefusion-optimized (UFO) design. These gp41<sub>ECTO</sub>-swapped trimers can be produced in CHO cells with ...[more]
