EnceVir (Tick-borne encephalitis vaccine, Russia)

What is tick-borne encephalitis (TBE)?

Tick-borne encephalitis (TBE) is an illness caused by a virus spread through tick bites. You can also get TBE by eating or drinking unpasteurized dairy products (such as milk and cheese) from infected goats, sheep, or cows.

Symptoms include fever, achiness, loss of appetite, headache, nausea, and vomiting. Swelling of the brain and/or spinal cord, confusion, and sensory disturbances occur in 20-30% of people with TBE. One percent of people die from this infection.

Currently there are four licensed TBE vaccines, two in Europe and two in Russia. These vaccines are all quite similar formalin-inactivated virus vaccines but the each use a different virus strain for production.

EnceVir (Russia) helps with specific prevention of tick-borne encephalitis in persons 18 years old and above. Three doses are administered at intervals of 1–7 months between the first and second, and 12 months between the second and third doses.
