Laboratory workers who may be exposed to JE virus are recommended to receive JE vaccine

Japanese encephalitis (JE) vaccination is recommended for all research laboratory workers who may be exposed to the virus.

People who are at ongoing risk of exposure to JE virus may need booster doses. 

The need for a booster dose of JE vaccine depends on: 

• the person’s age when they received their primary vaccination course 
• the vaccine used for the primary course 

See Table. Recommended doses of Japanese encephalitis vaccines.
