The Full Story
Japanese encephalitis is a serious mosquito-borne viral infection that can inflame the brain and cause lasting neurological damage. Vaccines were developed and introduced in the 1950s, with later improvements making them safer and more widely available. These vaccines became especially important in Asia, where the virus is endemic and transmission can be seasonal. Immunization remains one of the best ways to prevent severe disease in children and travelers to risk areas.
