Planning a long trip to a high-risk destination? If your travels will take you to parts of Asia, Africa, Central or South America (particularly for extended stays or rural exposure), rabies vaccination may be an essential part of your health preparations. One of the most common questions we’re asked at Chelsea Green Pharmacy the Travel Clinic is: How long does the rabies vaccine last, and will I need a booster?
Whether you’re embarking on a gap year, volunteering abroad, or working in remote areas, understanding your vaccine protection timeline is key to staying safe. Here’s what every long-term traveller should know.
What Is Rabies and Why Is It a Risk?
Rabies is a deadly viral infection transmitted through the saliva of infected animals, typically via bites or scratches. Dogs are the most common source of rabies transmission globally, but the disease can also spread through monkeys, bats, and other mammals.
Once symptoms appear, rabies is almost always fatal. That’s why prevention is critical, and why vaccination is highly recommended for long-term travel to high-risk areas where medical care may be limited or delayed.
Pre-Exposure vs Post-Exposure Rabies Vaccines
There are two types of rabies vaccinations: pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP).
Pre-Exposure (PrEP)
This is the vaccination you get before travel. It prepares your immune system in advance and reduces the number of injections you would need after potential exposure. It is particularly recommended for:
-
Long-term travellers or expats in rabies-endemic countries
-
Backpackers visiting remote regions
-
Animal handlers, vets, or wildlife workers abroad
-
Volunteers, aid workers or researchers in rural areas
-
Children, who are more likely to interact with animals and less likely to report bites
The standard pre-exposure course consists of three doses administered on days 0, 7, and 21 or 28.
Post-Exposure (PEP)
This is the course of treatment you receive after being bitten, scratched or licked by a potentially rabid animal. If you’ve never had the pre-exposure vaccine, you’ll need multiple rabies vaccine doses and potentially rabies immunoglobulin (RIG) — which may be difficult to source in some countries.
If you’ve already had the pre-exposure course, you’ll only need two additional doses of vaccine, and you can avoid the need for immunoglobulin. This simplifies post-exposure treatment and reduces the urgency to find full medical care immediately.
So, How Long Does the Rabies Vaccine Last?
If you’ve completed the full three-dose pre-exposure rabies vaccination schedule, your protection doesn’t last indefinitely — but it does provide several years of baseline immunity.
According to UK guidelines and the World Health Organization:
-
A booster dose is recommended after 1 year if you remain at continuous risk
-
After the first booster, further boosters are usually needed every 3 to 5 years for those with ongoing exposure risks
-
You may also consider a blood test (rabies antibody titre) to confirm your level of protection, particularly if it’s been more than 3–5 years since your last dose
For post-exposure vaccination, the goal is to provide immediate protection against the disease. However, if you’re in a remote area without vaccine access, delays in treatment can be life-threatening, which is why pre-exposure vaccination is the safest choice for long-term travellers.
Do I Still Need Treatment If I’m Bitten After Having the Vaccine?
Yes, even if you’ve had the pre-exposure course, you must seek medical attention immediately after any suspected exposure. But the difference is significant: you’ll only need two follow-up doses of vaccine, and you won’t require immunoglobulin, which can be expensive, hard to find, or even unavailable in some parts of the world.
Why Rabies Vaccination Matters for Long-Term Travel
If your trip will take you to high-risk countries for more than a few weeks, especially if you’ll be:
-
Staying in rural locations
-
Working with animals
-
Travelling without guaranteed access to healthcare
-
Engaging in outdoor or adventure activities
Then pre-exposure vaccination offers peace of mind and real protection. Rabies prevention is not just a box to tick; it’s a lifesaving measure.
