Japanese Encephalitis

What is the Japanese Encephalitis vaccine service? 

Japanese Encephalitis is not found in the UK, but rather in other areas around the world. This infection is rare but serious and is common in Indonesia, South Korea, Japan, China, India and Southeast Asia.  

For those planning to visit these parts of the world, a vaccine is recommended to reduce the risk of this infection.  

Why is the Japanese Encephalitis vaccine recommended? 

This infection is spread through mosquito bites, a common insect in rural areas of Asia. The longer you are visiting these areas, the more likely you are to be exposed and bitten. Therefore, the Japanese Encephalitis vaccine is recommended for those who are: 

• Staying for more than a month 
• Staying in rural areas 
• Staying near or visiting rice fields, wetlands or where pigs are kept.  

Travelling safely and avoiding the risk of infection is important, as Japanese Encephalitis can be life-threatening! 

In addition to the vaccine, other ways you can protect yourself from this illness include wearing insect repellent (with at least 50% DEET), sleeping under a mosquito net treated with insecticide and wearing long-sleeved tops, trousers, long skirts, socks and shoes. 

What are the symptoms of the infection? 

Most people who are infected experience this illness without any symptoms. However, common symptoms of Japanese Encephalitis are flu-like, such as a headache, high temperature, tummy pain and nausea or vomiting.  

It is usual for these symptoms to clear on their own, but unfortunately, for some people, this infection can spread to the brain, causing more serious symptoms like: 

• A severe headache 
• Feeling confused 
• Not being able to feel or move parts of the body (paralysis) 
• Seizures  

If you are experiencing these serious symptoms whilst abroad, please get medical attention quickly! However, if you are experiencing this upon returning, call 999. 

How can a pharmacy help? 

At Allied Pharmacy, this vaccination is included under the Travel Health Clinic service. This means protection against foreign infections is more easily available and accessible.  

We advise you to speak to our pharmacist for advice and guidance on when to have your vaccine and to arrange an appointment. This is so the vaccine has enough time before your trip to become effective.
