Japanese Encephalitis Vaccination

Japanese Encephalitis (JE) is a life-threatening viral brain infection which is spread to humans via infected bite of a Culex mosquito. The virus is found in areas of south-east Asia and the Indian subcontinent. The infection affects the brain causing neurological problems. It is estimated that there are around 70,000 cases each year, with 20,000 of those being fatal. There is no specific cure for the illness and therefore treatment is supportive rather than curative.

A vaccine is available and strongly recommended as the best form of prevention.

Who should have the Japanese Encephalitis vaccine?

Vaccination is advised for travellers who:

  • Plan to travel to areas where Japanese Encephalitis occur are at risk of infection, especially during prolonged stays in rural areas.
  • Will spend prolonged periods of time in an area that transmits JE
  • Plan to do outdoor activities such as camping and hiking
  • Will be staying in rural or agricultural areas, especially those staying overnight
  • Are travelling to an area of a known outbreak of JE (recent outbreaks include Assam in India and Myanmar)
  • Will be unable to prevent mosquito bites

How many doses are required for immunity?

At least 2 doses.

The second vaccine should be given 28 days after the first dose. A booster vaccine is also recommended.

How do we vaccinate against Japanese Encephalitis?

The Japanese Encephalitis vaccination can safely be given to infants from 2 months of age and upwards.

Protection requires 2 doses of the vaccination to be given over a 28 day period. It is recommended that travellers have their second dose at least 7 days before you travel. However, if rapid protection is needed, adults can receive the vaccination course over 7 days, so it is never too late to vaccinate – even for last-minute travellers. A third booster dose is also recommended 1 year later.

How is Japanese Encephalitis transmitted?

JE is transmitted mainly by night-biting mosquitoes that have bitten farm animals (particularly domestic pigs or birds).

It is mainly a seasonal disease prevalent during and after the monsoon season but can occur all-year-round in the tropics.

What are the symptoms of JE?

It can take 5-15 days after being bitten by an infected mosquito for symptoms to occur.

Many people will have no symptoms or mild flu-like symptoms. However, for around 1 in 250 people will develop more severe symptoms as the infection spreads to the brain. Initial symptoms of JE include a fever, headache and vomiting. It can progress and cause changes to mental status, neurological symptoms, weakness and movement disorders. Seizures are also very common, particularly in children. Up to 1 in 3 people who develop these more serious symptoms will die. Even those who recover can take several months and many are left with permanent brain damage.

How can I prevent JE?

The best way to prevent JE is through vaccination.

However, it is also recommended that you protect yourself from mosquito bites as a form of prevention. Wearing long loose clothing, using insect repellent with a minimum of 50% DEET, sleeping under mosquito nets, using plugin vaporisers and treating clothes with permethrin are advised to protect against mosquito bites.

Travelling the world is one of life’s greatest joys, whether it be a holiday or a business trip.

Visiting different countries and experiencing different cultures is extremely exciting but unfortunately it does come with some increased health risks. We understand seeking travel health advice isn’t the most exciting aspect of planning your trip but travelling unprepared dramatically increases your risk of getting an incurable or even fatal preventable-disease.

A consultation with an expert travel nurse and a couple of vaccinations could be the difference between you staying healthy and enjoying your travels and you being seriously unwell.

FAQs

After the initial course of 2-doses you will need a booster vaccine 12 – 24 months after your first vaccination.

If you are experiencing symptoms of JE it is important to seek medical attention. They will likely conduct a variety of blood tests which can confirm infection. As there is currently no cure for JE, vaccination is advised if you’re at risk.

Aside from getting the JE vaccine, travelers can also use DEET to deter mosquitoes so that bites are less likely. Sleeping in a mosquito net will help throughout the night and a colder, air conditioned room is better. Wearing long sleeves and trousers will also provide some protection.

It takes roughly 5 – 15 days after the bite from an infected mospitao to develop symptoms. This can mean you experience symptoms when back in the UK. If you need to seek medical help, you should explain you’ve recently traveled and where to help speed up diagnosis.

We will discuss your travel plans in detail, so a copy of your travel itinerary including proposed dates of travel, destination(s) you’re travelling to and length of your stay are all helpful details for our nurses. We’ll also discuss your health so information about your vaccination history to date is useful, as well as any medication you are currently taking.

We will most likely vaccinate you upper arm, we would therefore advise you to wear loose comfortable clothing for ease of access to your upper arm for vaccination.
