INDICATION & USAGE
IXIARO is a vaccine indicated for the prevention of disease caused by Japanese encephalitis virus, approved for use in individuals 2 months of age and older.
Important Safety Information
Severe allergic reaction after a previous dose of IXIARO, any other Japanese encephalitis vaccine, or any component of IXIARO, including protamine sulfate ─ a compound known to cause hypersensitivity reactions in some individuals ─ is a contraindication to administration of IXIARO. Individuals with a history of severe allergic reaction to another Japanese encephalitis vaccine may be referred to an allergist for evaluation if immunization with IXIARO is considered.
Vaccination with IXIARO may not protect all individuals. Individuals with a weakened immune system may have a diminished immune response to IXIARO. Fainting may occur when receiving any injection, including IXIARO. Tell your healthcare practitioner if you have a history of fainting from injections.
The most common (>10%) adverse reactions were: fever, irritability, diarrhea, and injection site redness in infants 2 months to <1 year of age; fever in children 1 to <12 years of age; pain and tenderness in adolescents 12 to <18 years of age; and, headache, muscle pain, and injection site pain and tenderness in adults.
You are encouraged to report negative side effects of vaccines to the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC). Visit www.vaers.hhs.gov or call 1-800-822-7967. You should ask your healthcare practitioner for medical advice about adverse events.
For more information, please see the physician’s Prescribing Information and ask your healthcare practitioner about the risk and benefits of IXIARO.

There’s also no treatment beyond basic, supportive care:
People who experience mild, flu-like symptoms can take standard remedies to help reduce discomfort, like fever and ache reducers.
People who suffer a severe infection will be treated with immediate life-support measures. Up to 30% of those will die.
Up to half of survivors of severe infection may suffer from persistent neurological problems such as paralysis, recurring seizures, or the inability to speak. The treatment for these issues is typically long-term rehabilitation.
Thankfully, it’s rare to suffer serious consequences. Still, it’s a good idea to reduce your exposure and protect yourself:
PROTECT YOURSELF
BARRIER PROTECTION
Use insect repellent on both skin and clothes, and wear clothes that cover exposed skin.
ENVIRONMENTAL PROTECTION
Stay in places with air-conditioned or screened rooms or use bed nets and aerosol spray room insecticides.
Reduced exposure
Keep your outdoor activities to a minimum, especially during peak biting hours, such as from dusk to dawn.
VACCINATION
See a travel health professional before your trip to see if vaccination is right for you.
In fact, JE vaccination is routine and often mandatory across the regional parts of Asia and the western Pacific. It’s what the locals do.
Even if you’ve taken every precaution against being bitten, mosquitoes are a crafty bunch. If any of the following is true about your upcoming trip, vaccination might be the way to go:
- Do you travel frequently to Asia, are you planning a long trip (e.g., a month), or will you be taking up residence?
- Is it possible you might participate in unplanned excursions and/or activities (i.e., something you would learn about once you’re there)?
- Will you be spending time outdoors (day or night) sight-seeing, exploring, hiking, fishing, biking, camping, etc.?
- Is there a chance you’ll be staying in accommodations without air conditioning, screens or bed nets?
The good news is, there’s a vaccine that’s safe and effective.
