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:
- have had an allergic reaction after a previous dose of JE-Vax® or IXIARO®.
- Have a bleeding disorder or a reduction in blood platelets, which increases risk of bleeding or bruising (thrombocytopenia) and cannot receive injections in the arm.
- have a weakened immune system, for example, due to a genetic defect or HIV infection.
- are or may be pregnant, or are breast feeding.
- currently have any illness with a fever of more than 100°F (37.8°C).
- take any medicines, even those you can buy over the counter.
