Abstract excerpt
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne viral disease with high case-fatality rates in East Asia, yet no licensed vaccines are currently available. Here, we generated attenuated severe fever with thrombocytopenia syndrome virus (SFTSV) strains through serial passage in Huh-7 cells and evaluated their pathogenicity, immunogenicity, and protective efficacy. Attenuation...
