European Tick-borne Encephalitis Vaccine

Protection

This vaccine protects against European tick-borne encephalitis and its complications. It is only recommended for certain travellers who will be spending time in a region with a medium to high risk of infection, and engaging in outdoor activities for extended periods (several weeks) in grassy or wooded areas.

Vaccine

Vaccination is one of the ways to protect against European tick-borne encephalitis. To ensure the best protection possible, three doses of the vaccine are recommended. A booster dose may be administered 3 years later if the risk is ongoing.

The European tick-borne encephalitis vaccine is safe. Most reactions are harmless and do not last long. Symptoms experienced after vaccination are not necessarily caused by the vaccine.

Reactions

Possible reactions to the vaccine:	What to do:
Pain at the injection site (10-49%)	Apply a cold, damp compress to the injection site
Joint and muscle pain, headache, fatigue or malaise (1-9%)	Take acetaminophen or ibuprofen for temperature of 38.5°C or higher See a doctor if symptoms are severe

As with any drug or biological product, an allergic reaction may occur. If a severe allergic reaction occurs, it begins within minutes and the person administering the vaccine will be able to treat it. That is why you are advised to remain at the clinic for at least 15 minutes after the vaccine is administered.

If you have any questions, ask the person administering the vaccine or contact Info-Santé (8-1-1) or your doctor.
