What is Japanese Encephalitis?
Japanese Encephalitis (JE) is a viral infection which is transmitted to humans through the bite of infected mosquitoes. It is most common in rural and agricultural areas of Asia and the Western Pacific. While many cases are mild or asymptomatic, severe cases can lead to inflammation of the brain, causing neurological complications, coma, or even death.

Who Needs the Japanese Encephalitis Vaccine?
The Japanese encephalitis vaccine is recommended for:

Travelers spending extended time (e.g., a month or more) in rural or agricultural areas where JE is endemic
Short-term travelers visiting JE-endemic areas during the transmission season (e.g., monsoon or post-monsoon periods) if they plan to engage in high-risk activities such as hiking, camping, or staying in rural accommodations
Residents or expatriates in JE-endemic areas
Laboratory workers handling the Japanese encephalitis virus
Children traveling to high-risk areas, as they are more susceptible to severe outcomes

The JE vaccine is typically administered as two doses:

First Dose: At any given time

Is There an Accelerated Course for Travel?
An accelerated schedule may be available in some cases, depending on the vaccine brand, for travelers needing faster protection.

How Long Does the Japanese Encephalitis Vaccine Last?

Protection lasts for up to 12–24 months following the full vaccination course.
