What is Japanese Encephalitis?
Japanese Encephalitis (JE) is a serious viral infection affecting the brain. It is caused by the Japanese Encephalitis virus, which is spread to humans through the bite of Culex mosquitoes. Most people do not develop symptoms, but it can lead to long-term neurological problems or death.
Japanese Encephalitis vaccine is a critical defence for anyone visiting rural or agricultural regions of Asia where mosquito-borne encephalitis poses a serious risk. Star Pharmacy offers expert guidance on scheduling and personalised care to ensure you travel safely.

About the Japanese Encephalitis Vaccine
The Japanese encephalitis vaccine protects against a potentially fatal neurological disease caused by the Japanese encephalitis virus (JEV), which is mainly prevalent in rural areas of Asia and the Western Pacific.
By stimulating your immune system to produce neutralising antibodies, the vaccine prevents virus replication in the central nervous system and significantly reduces the risk of complications like severe encephalitis, paralysis or death.
JE Vaccine
- Vaccine Type: Inactivated, purified virus vaccine grown in cell culture
- Mechanism of Action: Presents viral antigens to the immune system without live virus, prompting a durable IgG antibody response
- Duration of Protection: Well tolerated, safe in young children (from 2 months), adults and older travellers; no risk of vaccine-induced infection
