Japanese encephalitis vaccine is a vaccine that protects against Japanese encephalitis.[2] The vaccines are more than 90% effective.[2] The duration of protection with the vaccine is not clear but its effectiveness appears to decrease over time.[2] Doses are given either by injection into a muscle or just under the skin.[2]

It is recommended as part of routine immunizations in countries where the disease is a problem.[2] One or two doses are given depending on the version of the vaccine.[2] This should be completed at least a week before exposure.[3] Extra doses are not typically needed in areas where the disease is common.[2] Otherwise doses can be given after a year and after 10 years.[4] In those with HIV/AIDS or those who are pregnant an inactivated vaccine should be used.[2] Immunization of travellers who plan to spend time outdoors in areas where the disease is common is recommended.[2]

The vaccines are relatively safe.[2] Pain and redness may occur at the site of injection.[2] As of 2015, 15 different vaccines are available:[2] some are based on recombinant DNA techniques, others weakened virus, and others inactivated virus.[2]

The Japanese encephalitis vaccines first became available in the 1930s.[5] It is on the World Health Organization's List of Essential Medicines.[6] In the United States it costs between 100 and 200 USD for a course of immunizations.[7] In the UK it costs the NHS around £120 for a course, as of 2022.[4]
