As with all injectable vaccines, appropriate medical treatment and supervision should always be available to treat rare cases of anaphylactic reactions following the administration of the vaccine.

  • IXIARO* must never be injected into a vein or any blood vessel.
  • As with any other vaccine, vaccination with IXIARO* may not result in protection in all cases.
  • IXIARO* will not protect against encephalitis caused by other organisms.
  • Like other intramuscular injections, this vaccine should not be administered intramuscularly to persons with thrombocytopenia, hemophilia or other bleeding disorders.
  • If your immune system does not work properly (immunodeficiency) or you are taking medicines affecting your immune system (such as a medicine called cortisone or cancer medicine), protection may not be as expected.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you get IXIARO*. Talk about any health conditions or problems you may have, including if:

  • you have a bleeding disorder (a disease that makes you bleed more than normal) or a reduction in blood platelets, which increases risk of bleeding or bruising (thrombocytopenia).

  • you have any known allergies.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
