Japanese Encephalitis Vaccine

What is Japanese Encephalitis and where can it be found?

Japanese Encephalitis is a very rare viral brain infection found in pigs and birds. When a mosquito bites the infected animal, they can then pass the virus onto humans. Japanese Encephalitis is most common in rural parts of the Far East, Pacific Islands and Southeast Asia.

It is very rare for travellers to contract this virus, less than 1 in a million travellers a year are known to get it. The people at highest risk are those staying for longer periods of time in rural areas, in particular pig farms and rice fields, however it has also been found in urban areas. 75% of cases are reported in children under 15 years of age.

Symptoms of Japanese Encephalitis can include:

  • High temperature
  • Stiff neck
  • Difficulty with speech
  • Tremors/shaking of body parts
  • Weakness of muscles / unable to move
  • Seizures

If you are planning a long stay (usually at least a month) in a country where you are at risk of contracting the virus, it is recommended to have the Japanese Encephalitis Vaccination.

Japanese Encephalitis Vaccination:

The Japanese encephalitis vaccine consists of 2 injections, with the second dose usually given 28 days after the first. You will need to have the second dose a week before you travel. Booster doses are also required for those at ongoing risk. The vaccine is said to protect 9 out of 10 people.

The Japanese Encephalitis vaccine can be given to adults and children over 2 months.
