Vaccination is the best protection against Japanese encephalitis and its complications. Several doses of vaccine are required to obtain the best possible protection.
Some symptoms may be caused by the vaccine (e.g. redness at the injection site). Other problems may occur by chance and are not related to the vaccine (e.g. cold, gastro, headache).
Japanese encephalitis vaccine is safe. In most cases, it does not cause any reaction.
|Frequency||Possible reactions to the vaccine||What to do|
(less than 50% of people)
(less than 10% of people)
We recommend that you stay at the clinic for at least 15 minutes after vaccination because allergic reactions may occur. If an allergic reaction occurs, the symptoms will appear a few minutes after the vaccination. The person giving the vaccine will be able to treat this reaction immediately.
For any questions, contact the person giving the vaccine, or Info-Santé 811 or your doctor.
