Japanese Encephalitis Vaccine Shortage (2026): In Stock in West London
September 10, 2026
6 minute read
Quick answer: yes, there is a UK-wide shortage of the Japanese encephalitis vaccine (Ixiaro). Ealing Travel Clinic in West London currently holds stock, subject to availability, and can start your course the same day where suitable, including the licensed accelerated 7-day schedule for adults.
Supply status, 10 September 2026: NaTHNaC lists Ixiaro as out of stock nationally, with supply expected to begin recovering from around September 2026. This is an estimate and availability varies between providers, so please confirm with us before you travel.
What is happening with the Japanese encephalitis vaccine shortage?
Ixiaro is the only Japanese encephalitis vaccine licensed in the UK, so when supply is disrupted there is no alternative brand to fall back on. NaTHNaC has confirmed the vaccine is out of stock nationally, with supply anticipated to recover from around September 2026. Because there is a single manufacturer, shortages like this have happened before and can take time to clear.
The practical effect is that some travellers cannot find the vaccine, and others have started a course but been unable to get their second dose in time. If you have a trip to an at-risk area coming up, the sensible step is to book an assessment early rather than assume a vaccine will be available at short notice.
We have the vaccine in stock, book while it is available
We currently hold Japanese encephalitis vaccine stock, subject to availability. Because national supply is limited, we would encourage you to book or call to confirm before travelling. You can check availability and book online, or call us on 0208 567 0982. If you began a course elsewhere and were unable to complete it, contact us and we will advise on your options.
Standard vs accelerated schedule
The Japanese encephalitis vaccine is given as two doses. The standard schedule spaces them 28 days apart. For adults aged 18 to 65 there is also a licensed accelerated schedule, with the two doses just seven days apart, and studies show it gives similar protection to the standard course. This is especially useful when both time and supply are short.
| Schedule | Doses and timing | Who it is for | Finish before travel |
|---|---|---|---|
| Standard | 2 doses, 28 days apart | From 2 months of age | At least 7 days before |
| Accelerated | 2 doses, 7 days apart | Adults 18 to 65 | At least 7 days before |
If you need ongoing protection, a booster is recommended within 12 to 24 months. We will confirm the right schedule for you at your appointment.
Do you actually need the Japanese encephalitis vaccine?
Japanese encephalitis is a mosquito-borne infection found in rural and agricultural parts of Asia and the western Pacific, particularly where there are rice paddies and pig farming. It is rare in travellers, but it is serious when it does occur and there is no specific treatment. It is usually recommended for people spending longer periods, or the transmission season, in rural at-risk areas, or doing a lot of outdoor activity.
Whether you need it depends on exactly where you are going, for how long and at what time of year. Our full guide explains this in detail: who needs the Japanese encephalitis vaccine. If your trip is to China or Vietnam, we cover those destinations specifically too.
How much does the Japanese encephalitis vaccine cost?
At Ealing Travel Clinic the Japanese encephalitis vaccine is £110 per dose, or £220 for the full two-dose course, which includes your travel health consultation and vaccination record. The accelerated schedule is the same price.
