Japanese Encephalitis

Japanese Encephalitis (JE) affects thousands each year across Asia and the Western Pacific, with India among the countries most at risk. The virus spreads through the bite of infected Culex mosquitoes that breed in rice fields and rural water bodies. While most infections cause mild or no symptoms, severe cases can result in brain inflammation, high fever, seizures, or paralysis, particularly in children.

Vaccination remains the most effective and evidence-based prevention strategy. The JE vaccine helps the body build long-lasting immunity against the virus, preventing complications and reducing community transmission.

The Japanese Encephalitis Vaccine helps protect against:

• Infection with Japanese Encephalitis Virus (JEV)
• Neurological complications such as encephalitis and seizures
• Long-term cognitive or motor impairments resulting from brain inflammation

It provides immunity against the Japanese Encephalitis Virus (Flavivirus JEV), reducing the risk of severe illness and death in both children and adults.

• Shields against life-threatening brain infection and complications
• Provides long-term protection, endorsed by WHO and CDC guidelines
• Safe and approved for use under India’s Universal Immunisation Programme (UIP)
• Strongly advised before travelling or living in rural or endemic areas
• Helps build herd immunity and reduces community-wide transmission
• Prevents emotional and financial stress linked with prolonged illness or hospitalisation

The Japanese Encephalitis Vaccine has an excellent safety profile. Any side effects are usually mild and short-lived:

Follow these safety precautions before receiving the JE vaccine:

• Inform your doctor about allergies or prior vaccine reactions
• Postpone vaccination if you have a high fever or severe illness
• Minor colds or mild fever are not a contraindication
• Eat lightly and stay hydrated before your appointment
• Wear short-sleeved or loose clothing for easier access to the upper arm
• Remain at the clinic for 15 minutes after vaccination for observation
