Planning a trip abroad with your family can be one of the most exciting and memorable experiences you share. But when your destination includes regions in Asia, it also brings added health considerations, especially for your children. One question we hear frequently from parents at Sudbury Court Pharmacy and Travel Clinic is: Do children need the Japanese encephalitis vaccine before travelling?

The short answer is: it depends on your destination, travel plans, and the length of your stay. But if you’re travelling to certain parts of Asia (particularly rural or agricultural areas), the Japanese encephalitis vaccine could be an essential part of your child’s travel protection plan.

What is Japanese Encephalitis?

Japanese encephalitis (JE) is a serious viral infection spread through the bite of infected mosquitoes. It’s caused by the Japanese encephalitis virus, which is most common in rural areas of Southeast Asia, the Indian subcontinent, and the Far East. The virus tends to be most active during and after rainy seasons, when mosquito populations are highest.

While many people infected with JE may experience only mild or no symptoms, the disease can progress to cause inflammation of the brain, leading to seizures, confusion, long-term neurological damage, or even death. Children are particularly vulnerable to these complications, which is why prevention is so important.

Where is The Risk Highest?

Your child’s risk of contracting Japanese encephalitis depends largely on where you’re going and the nature of your travel. JE is most commonly found in countries such as:

• Thailand

• Vietnam

• Cambodia

• Laos

• Indonesia (including Bali)

• The Philippines

• Parts of India, China and Nepal

Risk increases significantly if you’re visiting rural or farming regions, especially rice fields and areas with standing water, where mosquitoes breed. Long stays, backpacking holidays, or spending time outdoors in the evening or overnight also increase the likelihood of exposure.

Urban areas and short resort stays pose a much lower risk, though it’s still important to assess each trip individually.

At What Age Can Children Get the Japanese Encephalitis Vaccine?

The Japanese encephalitis vaccine is licensed for children aged 2 months and above in the UK. It’s administered as a two-dose schedule, usually spaced 28 days apart, so planning is key, especially if you’re travelling during school holidays or a busy season.

For children at risk, the vaccine is safe, effective, and well-tolerated. Side effects are typically mild and may include soreness at the injection site, a low-grade fever or irritability, particularly in younger children. Our clinicians will guide you through what to expect and answer any questions you may have before proceeding.

Is the Vaccine Really Necessary?

This is where expert consultation makes a difference. The Japanese encephalitis vaccine isn’t automatically given to every traveller, and it isn’t required for entry into any country. However, that doesn’t mean it’s not important.

If your child is going to be in high-risk areas or spending extended periods outdoors in regions where the virus is present, vaccination offers a safe and highly effective way to protect them from a potentially life-threatening illness.

At Sudbury Court Pharmacy and Travel Clinic, we don’t rely on guesswork. We provide tailored advice based on your itinerary, your child’s age and medical history, and up-to-date guidance from health authorities such as the NHS, WHO, and NaTHNaC.

Can’t I Just Rely on Mosquito Precautions?

Insect repellent, mosquito nets and appropriate clothing are all essential parts of protection, but they aren’t foolproof. Mosquitoes that carry the JE virus tend to bite in the early evening and overnight, making it difficult to avoid exposure entirely.

Vaccination is the only method that provides specific, long-term protection against Japanese encephalitis. When used in conjunction with bite avoidance measures, it significantly reduces your child’s risk.
