Japanese Encephalitis Vaccine Information Sheet (VIS)


What is Japanese Encephalitis?

This condition, which is often just called JE is a serious infection that results from a virus. It occurs (mostly) in rural parts of Asia.

Encephalitis refers to brain swelling and it is acquired through the bite of infected mosquitoes which carry the virus. This form of encephalitis is not able to be spread from one person to another.

If a person contracts this virus, it can cause a number of medical problems including:

  • Headaches, fever and difficulty thinking.
  • Severe infections may even result in death.

Who needs the Japanese Encephalitis vaccination? When?

Anyone who lives in or is traveling to certain rural areas of Asia for extended periods should receive the vaccine. Also, any lab workers who are at risk of being exposed to the JE virus need to receive the vaccination.

The vaccine is given in two doses that should be spaced 28 days apart. The second dose should also be given about 10 days prior to arriving in the risk area to assure full protective immunity. Booster (a third) doses will be needed after two years but only if continued exposure to the JE virus exists.

What are the risks of the Japanese Encephalitis vaccine?

The mild symptoms of this vaccine include fever, muscle pain, headache, abdominal pain, chills, rash, dizziness, vomiting, and nausea.

There are some serious allergic reactions that may very rarely occur as well, including hives and swelling of the lips, face, feet, and hands, as well as difficulty breathing. These usually occur in just minutes after receiving the vaccination is given and may require special treatment.
