Antigenic Chimeric Tick-Borne Encephalitis Virus/Dengue Virus Type 4 Recombinant Viruses
The tick-borne encephalitis virus (TBEV) complex is a group of viruses that can cause severe neutrotropic disease and up to thirty percent (30%) mortality. While these viruses can be found in many parts of the world, the largest impact of the disease occurs in Europe and Russia, where approximately fourteen thousand (14,000) hospitalized TBEV cases occur annually. TBEV is in the family Flaviviridae, genus flavivirus and is composed of a positive-sense single stranded RNA genome that contains 5' and 3' non-coding regions and a single open reading frame encoding ten (10) proteins.
