Tell your doctor if you have any severe allergies. People who have had a severe reaction or developed a severe allergic reaction to a previous dose of JE-Vax® or IXIARO® should not be revaccinated.
Pregnant women should generally not receive JE vaccine. Check with your doctor since it could be recommended under certain circumstances.
If you will be traveling for fewer than 30 days, especially if you will be staying in major urban areas, tell your doctor. You may be at lower risk and not need the vaccine.
Anyone who has a life-threatening allergy to any component of IXIARO® should not get the vaccine. IXIARO® contains protamine sulfate, known to cause hypersensitivity reactions in some individuals. Safety and effectiveness of IXIARO® has not yet been established in pregnant women or nursing mothers.
You should tell your health care provider if you:
People with multiple allergies, especially those with a history of allergic urticaria (hives), are at higher risk for allergic complications after JE immunization. Under normal circumstances, those immunized should not travel internationally within 10 days of immunization because of the possibility of delayed allergic reactions that may require medical attention. At this time no other precautions are recommended for IXIARO®.
