Tick-borne encephalitis vaccine helps to form a stable immunity to the virus and is an encephalitis virus that is inactivated by formalin.
For the initial course of vaccination, it is enough to make three injections of this drug. The first two injections are carried out approximately in November-December with an interval between them of at least two weeks, but not later than a month later. The third injection is given three months after the last vaccination, but it cannot be given later than two weeks before visiting the site of possible infection.
If there are cases of emergency prophylaxis, then the tick-borne encephalitis vaccine is administered twice a month or two, and in the future it is sufficient to administer the indicated drug once a year.
Tick-borne encephalitis vaccine can be administered from the age of six to 1 ml of the drug in each dose, and for children who are four to six years old, 0.5 ml of the drug. The vaccine is administered exclusively subcutaneously in the region of the lower angle of the scapula. In other parts and tissues of the body, the introduction of a vaccine is prohibited.
Tick-borne encephalitis vaccine can be given together with inactivated as well as live vaccines. If it is necessary to introduce immunoglobulin against tick-borne encephalitis, then the interval between its administration and this vaccine should be at least a month.
Possible side effects
If the patient has hypersensitivity to chicken protein or other components of the tick-borne encephalitis vaccine, such negative effects as headache and a slight increase in body temperature, which disappear after two days, may occur.
During the first 5 days, local reactions may appear in the form of a burning sensation at the injection site, soreness, development of infiltrate and redness.
Encephalitis vaccine - indications for use
The specified tool is administered for routine preventive immunization in places where the risk of damage is increased and for people who visit foci of tick-borne encephalitis. Also, the drug is administered as an emergency if there is a suspicion of a tick bite in people living in regions endemic for tick-borne encephalitis.
Encephalitis vaccine - contraindications
This vaccine should not be administered if a person has a febrile condition, if there are progressive or hereditary diseases of the central nervous system. Contraindications to use are food allergies, epilepsy with frequent seizures, collagenoses, cerebrovascular accident, bronchial asthma, chronic heart failure, as well as liver, kidney, diabetes, malignant neoplasms, thyrotoxicosis, pregnancy and blood diseases.
After the patient has suffered a febrile state, the vaccine is allowed to be administered no earlier than a month after its full recovery. For people who have had a meningococcal infection or viral hepatitis, the drug can be administered no earlier than six months after their full recovery. After delivery, after two weeks, you can do the vaccination.
If there is a real possibility of infection, the vaccine can be administered to children under the age of one year.
When vaccinating, avoid that the drug gets inside the vessels.
After a course of three vaccinations is completed, most people have immunity for at least 3 years. After this period, a single injection of the drug is carried out.
If you missed two revaccinations, you must start the entire course from the very beginning. For people who live and work in endemic regions, doctors recommend that re- vaccination against tick-borne encephalitis be carried out annually.
