EnceVir vaccine is a concentrated sterile purified suspension of the TBE virus strain 205, obtained by its reproduction in a primary weighed culture of chicken embryo cells and sorbed on aluminum hydroxide. The virus is inactivated with formalin.
When the vaccine is administered in the body, the production of specific antibodies to the TBE virus is stimulated. EnceVir protects against strains of the Far Eastern and European genotypes of this virus.
Indications for use

- vaccination of donors in order to obtain a specific immunoglobulin.
Contraindications

- a history of severe allergic reactions to foods (especially chicken protein) and drugs;
- bronchial asthma;
- systemic connective tissue diseases;
- a strong reaction or complications to the previous vaccination: an increase in body temperature above 40 ° C, hyperemia at the injection site with a diameter of more than 8 cm, edema;
- epileptic diseases with frequent seizures;
- somatic diseases in the stage of subcompensation and decompensation;
- endocrine system diseases, including diabetes, thyrotoxicosis;
- blood diseases;
- malignant neoplasms;
- pregnancy;
- age up to 18 years.
Care should be taken to vaccinate persons with a history of hypersensitivity to the chicken embryo protein, as well as with a history of cerebral disorders.

Instructions for use of EnceVir: method and dosage
The EnceVir vaccine is injected into the deltoid muscle of the shoulder (preferably the left one) in 1 dose (0.5 ml).
Before opening the ampoule, it should be visually inspected. Immediately before inoculation, the ampoule is warmed to room temperature, stirred by shaking to a homogeneous suspension, the neck of the ampoule is treated with alcohol. The vaccine is administered immediately after opening the ampoule. It is necessary to use an individual disposable syringe for each patient.

It is advisable to carry out both injections during the period from autumn to spring. But if necessary, vaccination can be carried out at any time of the year, including the epidemic season (summer period). A visit to the territory of the natural focus of TBE is possible not earlier than two weeks after the second vaccination;
- emergency vaccination: two injections of 1 dose (0.5 ml) of EnceVir.

It is recommended to visit the territory of the natural focus of TBE not earlier than two weeks after the second vaccination;
- revaccination: with both schemes, the first revaccination is carried out once in 1 dose (0.5 ml) of EnceVir 1 year after the course of primary vaccination, all subsequent revaccinations are performed once, 1 dose (0.5 ml) every 3 years.
