Overview

Japanese Encephalitis (JE) is a viral brain infection spread by Culex mosquitoes. These mosquitoes breed in rice paddies and stagnant water, and are most active at dusk and dawn. The virus is found across South and South-East Asia, including India, Nepal, Thailand, Vietnam, Cambodia, Indonesia, the Philippines, China, and Japan. Most people infected with JE virus have no symptoms or only mild flu-like illness. However, approximately 1 in 250 infections leads to severe encephalitis — inflammation of the brain — which carries a high fatality rate and frequently causes permanent neurological damage in survivors. At Holborn Clinic, we provide the Japanese encephalitis vaccine — the only JE vaccine licensed in the UK. The 2-dose course should ideally be completed at least 1 week before travel. We can plan the schedule around your other travel vaccinations to minimise the number of visits.

Holborn Travel Clinic is inside Boutalls Pharmacy at 60 Lamb's Conduit Street, London WC1N 3LW, minutes from Holborn and Russell Square stations.

Who Needs This Vaccine?

  • Travellers spending more than 1 month in endemic areas of South or South-East Asia.
  • Anyone visiting rural or agricultural areas, especially rice-farming regions where the virus is most common.
  • Travellers during or shortly after the monsoon season (June–October in most of Asia) when mosquito activity peaks.
  • Repeat travellers making multiple short trips to endemic regions.
  • Adventure travellers, backpackers, and volunteers who will spend significant time outdoors, particularly at dusk and dawn.

What to Expect

  • The course is 2 doses given 28 days apart. Each appointment takes approximately 15 minutes.
  • The vaccine is given as an injection in the upper arm.
  • You should complete the course at least 1 week before travel for full protection.
  • A booster dose may be recommended 1–2 years later if you continue to travel to risk areas.
  • Can be administered alongside other travel vaccines in the same visit — our pharmacist will plan your schedule.

Side Effects

  • Very common: soreness, redness, or swelling at the injection site.
  • Common: headache, muscle pain, or fatigue for 1–2 days.
  • Serious side effects are rare. Our pharmacist will screen for any contraindications before vaccination.

Japanese Encephalitis Vaccine FAQ’s

For short trips (under 1 month) to popular tourist areas, the risk is generally low and vaccination may not be necessary. However, if your trip includes rural areas, rice paddies, or outdoor activities during the rainy season, vaccination is recommended regardless of trip length. Our pharmacist will assess your specific itinerary.
