Japanese Encephalitis Vaccine

Service Description

Japanese Encephalitis is prevalent in Eastern and Southern Asia and is transmitted by mosquitos who bite livestock and then bite humans. The incubation period starts from around 5 days, and initial symptoms include fever, headache and nausea progressing to meningoencephalitis (swelling of the lining of brain) with convulsions and altered consciousness. Of those who develop encephalitis, approximately 30% die. In those who survive, it is estimated that 30-50% will develop long term neurological or psychiatric problems. Two doses are required for a full course, ideally starting 28 days before travel (although rapid schedules are also available)
