Japanese Encephalitis Vaccine

What is Japanese encephalitis?

Japanese encephalitis is a serious infection caused by a virus that affects the brain. It is most common in rural parts of Asia, especially where rice farming takes place. The virus is carried by certain mosquitoes that breed in rice paddies and standing water. It is not transmitted from person to person. Instead, it spreads through mosquito bites. Symptoms can include fever, headache, confusion, and in severe cases it can lead to swelling of the brain. Although it is relatively rare, it can become life threatening, which is why prevention is so important.

How do you get Japanese encephalitis?

You get Japanese encephalitis when an infected mosquito bites you. Mosquitoes pick up the virus by feeding on infected animals, often pigs or wading birds. When they bite humans, they pass on the virus. Travelling in areas where the virus is common increases your chances of encountering these mosquitoes. Outbreaks often happen during rainy seasons when mosquito populations are high.

Why am I at risk of getting Japanese encephalitis?

You may be at risk if you plan to stay in rural regions for an extended time or if you plan to visit areas with poor mosquito control. Travellers who enjoy outdoor activities such as camping or hiking are at higher risk. The virus can also be found in urban areas, but it is more common in places with rice fields or standing water. At Fulham Palace Pharmacy, we recommend that you take extra care if you are travelling to countries where the virus is regularly reported.

How can I prevent Japanese encephalitis?

One of the most effective ways to protect yourself is through je immunization, which offers you protection before you travel. It is also important to use mosquito repellents, wear clothing that covers your arms and legs, and sleep under mosquito nets if you are in high-risk areas. Staying in air-conditioned rooms or places with screens on doors and windows helps reduce the chance of mosquito bites. Avoiding strong fragrances can also be beneficial, as they might attract insects.

What side effects could I expect from a Japanese encephalitis vaccine?

All vaccines can cause mild side effects, and the Japanese encephalitis vaccine is no different. You may feel a bit sore where the injection took place or experience slight redness and swelling. Some people may also experience mild headaches or a general sense of feeling unwell. These symptoms usually clear up within a few days. Serious side effects are very rare, but it is always wise to discuss any concerns with our pharmacists at Fulham Palace Pharmacy. We can talk you through what to expect and how to manage any discomfort.

When to get vaccinated

It is best to plan your vaccination well ahead of your trip. The vaccine usually needs to be given at least one month before you travel to allow your body time to build immunity. If you have a more urgent travel schedule, speak to our team. We will do our best to make sure you are protected within the time you have. 

Who should get vaccinated?

Anyone who is travelling to regions where Japanese encephalitis is present should think about getting vaccinated, especially if they plan to spend time in rural areas. People with weaker immune systems or those who are at higher risk of severe disease should strongly consider vaccination. Our pharmacists at Fulham Palace Pharmacy will advise you based on your travel plans, overall health, and specific vaccination needs.

Course

The course for je immunization typically involves two doses. These are given a few weeks apart to ensure you develop a strong level of protection. It is important to complete the course even if your plans change. If you do not complete the full course, your protection might not be as effective. The Japanese encephalitis vaccine cost can vary, so speak with us to find out the most up-to-date pricing.

How it is given

At Fulham Palace Pharmacy, we administer the vaccine via an injection in your upper arm. It is a quick procedure carried out by a trained professional. We recommend that you relax your arm during the injection to minimise discomfort. You will be asked to wait in the pharmacy for a short period after receiving your vaccine, so we can be sure you feel well.

Children

Children can also receive the vaccine if they are travelling to areas with a high risk of Japanese encephalitis. The dosage or schedule might differ based on their age, so it is essential to discuss this with us. We want to ensure that every member of your family is protected in the safest and most appropriate way possible.

Additional precautions

Even after vaccination, it is wise to avoid mosquito bites. Use repellents containing DEET or other recommended ingredients. Wear long-sleeved shirts and long trousers, especially at dawn and dusk. Consider sleeping under a mosquito net if you are in an area with many insects. Keep in mind that no vaccine is 100 percent effective, so staying aware of prevention strategies is vital.
