In-silico design of envelope based multi-epitope vaccine candidate against Kyasanur forest disease virus

Abstract Kyasanur forest disease virus (KFDV) causing tick-borne hemorrhagic fever which was earlier endemic to western Ghats, southern India, it is now encroaching into new geographic regions, but there is no approved medicine or effective vaccine against this deadly disease. In this study, we did...
