How Effective is the Japanese Encephalitis Vaccine?

Japanese Encephalitis (JE) is a virus that is contracted through bites from infected mosquitos found in the Pacific Islands, the Far East, and rural areas of southeast Asia. Those most at risk of getting JE in these regions are people who spend a lot of time outside, are travelling during seasons when mosquitoes are most common, or are spending a significant amount of time in areas where Japanese Encephalitis is prevalent. 

Symptoms of Japanese Encephalitis
Japanese Encephalitis is a viral infection that targets the brain. Most people who get JE will experience mild symptoms or no symptoms at all. Because of this, JE is often mistaken as the flu. For those who do experience more severe symptoms, the disease will eventually spread to the brain and may culminate in death.

Severe Symptoms of Japanese Encephalitis Include:

  • Confusion
  • Tremors
  • Stiff neck
  • Muscle weakness or paralysis
  • Seizures (more common in children)
  • Muscle weakness or paralysis
  • The inability to speak

Of those who have more severe symptoms, a third of them will succumb to the disease. For the other two thirds, it can take months or years for symptoms to subside. Up to half of those who survive will have permanent and serious neurological damage such as paralysis, brain damage, and changes in personality.

Precautions Against Japanese Encephalitis
There is no cure for JE and because of the serious impacts it can have on your central nervous system, the best way to prevent it is through getting a Japanese Encephalitis vaccine. The JE vaccine is an injection that is given over 28 days in 2 doses. If you will be at risk of exposure for 12 months or more, it is recommended you get a booster shot. Other recommended additional precautions against Japanese Encephalitis are:

  • Use insect repellent
  • Wear long-sleeved shirts and long pants
  • Treat clothing and gear with permethrin (an insecticide)
  • Sleep under a mosquito net
  • Ensure any open windows have screens
