When Do You Need To Get the Japanese Encephalitis Vaccination

Japanese Encephalitis (JE) is a viral infection found in parts of Asia, the Middle East, and the western Pacific. It is spread through the bites of infected mosquitos.The risk for contracting JE is relatively low and depends on the duration and location of travel, the time of year, and the types of activities undertaken. It is most commonly found outdoors in rural areas, especially during the rainy seasons.

How Will I Know If I Contracted JE?

Most people who get infected with JE will only have mild flu-like symptoms if they have any at all. However, others may end up developing life-threatening symptoms like inflammation of the brain (encephalitis).

Symptoms of Japanese Encephalitis include:

  • High fever
  • Sudden, intense headaches
  • Seizures and tremors
  • Confusion and delirium
  • Coma

It is estimated that at least 20% of people who contract JE will die, but many of those who do not die will be left with chronic, life-altering symptoms. Up to 50% of Japanese Encephalitis survivors will experience persistent cognitive, neurological, and psychiatric symptoms long after the infection is gone.

Treatment and Prevention
There is no treatment for Japanese Encephalitis other than palliative care. Once infected and symptomatic, all doctors can do is monitor patients and try to ease any symptoms. 

The only way to prevent JE is through precautionary measures and vaccination. In fact, Japanese Encephalitis is the number one cause of vaccine preventable encephalitis in the western Pacific and Asia.

It is important to take safety measures in addition to vaccination. For longer periods of travel in endemic regions, preventing mosquito bites is very important. Minimise outdoor exposure, wear long sleeves and trousers, use mosquito repellent, and sleep under a mosquito net.

Precautions and Contraindications of the Vaccine
The vaccine is safe to receive, but it may not be suitable for some people. Allergic reactions to one of its compounds, protamine sulfate, have been reported. There have also been no tests done on those who are pregnant, but it is still recommended to be given to pregnant women who are at risk of the virus as the infection’s potentially devastating effects outweigh any vaccination risks.
