Crimean-Congo hemorrhagic fever virus (CCHFV) is the most widespread tick-borne zoonotic virus, with a 30% case fatality rate in humans. Structural information on the CCHFV membrane fusion glycoprotein Gc–the main target of the host neutralizing antibody response–and on antibody-mediated neutralization mechanisms are lacking. Here we describe the structure of pre-fusion Gc bound to the antigen-binding fragments of two neutralizing antibodies displaying synergy when combined, as well as the structure of trimeric, post-fusion Gc. The structures show the two Fabs acting in concert to block membrane fusion: one targeting the fusion loops and the other blocking Gc trimer formation. The structures also revealed the neutralization mechanism of previously reported anti-CCHFV antibodies, providing the molecular underpinnings essential for developing CCHFV-specific medical countermeasures for epidemic preparedness. The elucidation of antibody neutralization mechanisms of a highly pathogenic virus provides a foundation for epidemic preparedness.
