Vaccine (About this – PubMed Health)
Uses of This Medicine
Japanese encephalitis virus vaccine, inactivated adsorbed (IXIARO®) is used to prevent infection caused by the Japanese encephalitis virus. It works by causing your body to produce its own protection (antibodies) against the virus.
Japanese encephalitis is caused by the bite of a mosquito that lives in certain parts of Asia. It is a serious infection that can cause flu-like symptoms (eg, fever, chills, tiredness, headache, nausea, and vomiting), confusion, agitation, brain damage, and possibly death. This vaccine does not protect against encephalitis caused by other viruses.
This vaccine is only available from your doctor or other authorized health care professional.
