JE vaccine protects against the virus that causes Japanese encephalitis infection.
Vaccines can provide protection against a single disease or can be made to provide protection against more than one disease. Vaccines that provide protections against more than one disease are called combined vaccines.
The JE vaccine is only available as a single vaccine format.
Travellers 18 years of age and older who:
- will be traveling to high-risk areas for more than 30 days
- will be traveling to high-risk areas for less than 30 days but are planning to spend a lot of time outdoors
- will be close to rice culture or pig farming
This vaccine is considered a travel vaccine, and is not offered routinely as part of the Ontario Immunization Schedule.
- People who have had serious allergic reaction to any ingredient in the vaccine or to a previous dose of the vaccine itself should not receive the JE vaccine.
Your health care provider will ask you questions about your health before giving you any vaccine. This will help them identify allergies you might have and safely manage potential allergic reactions.
You could have mild side effects after being vaccinated, but they usually go away in one to two days. Some people can be allergic to the vaccine, just like they might have a food or medication allergy.
