Rabies post-exposure treatment: vaccinated vs not vaccinated
If you're bitten, scratched or licked by an animal in a rabies-risk country, the treatment you need depends heavily on whether you had the rabies vaccine before you travelled. Having had it makes treatment far simpler — and removes the need for rabies immunoglobulin, the part that is hardest to obtain abroad.

Why rabies is a medical emergency
Rabies is spread through the saliva of infected animals — most often dogs, but also bats, cats and monkeys — usually through a bite, scratch, or a lick on broken skin or the eyes, nose or mouth. Once symptoms appear, rabies is almost always fatal and there is no effective treatment. The good news is that it is virtually 100% preventable if the correct post-exposure treatment is started promptly. That is why what you do in the first hours after an exposure — and whether you were vaccinated beforehand — matters so much.
Avoiding rabies abroad: what to do — and what not to do
The single best protection is avoiding animal contact altogether. This is the official UK advice for travellers:
Don't
- Touch, feed or approach any animal — wild (including bats), stray or pet — even at temples, zoos, sanctuaries or markets.
- Assume a tame, friendly or healthy-looking animal is safe: rabid animals can seem unusually friendly and may show no signs at all.
- Pose for photos with animals or take part in animal-handling attractions.
- Leave food or litter lying around that could attract stray animals.
- Let children play with or approach animals unsupervised.
- Ignore a bite, scratch or lick — however minor — or wait until you're back in the UK to get treated.
Do
- Keep your distance from all animals, and supervise children closely around them.
- Teach children to tell an adult straight away if an animal touches, licks, scratches or bites them.
- Check children for any wounds after they've been near animals.
- Consider the pre-travel rabies vaccine — especially for remote, rural or long trips, or work with animals.
- If you are exposed, wash the wound at once and seek medical care locally — see the first-aid steps below.
First aid: what to do immediately after a bite or scratch
This applies to everyone — even if you have had the rabies vaccine:
- Immediately flush the wound under running water and wash thoroughly with soap for several minutes.
- Apply an antiseptic such as iodine or alcohol.
- Do not have the wound stitched straight away — suturing is delayed until treatment has started.
- Seek medical advice urgently and start rabies post-exposure treatment abroad — do not wait until you return to the UK.
- Keep a written record and photos of any vaccine or immunoglobulin given (name, type, dates).
Get assessed in person — every time. Any possible rabies exposure should be assessed at a hospital or other medical facility. A detailed wound and individual risk assessment is still needed in every case — even if you have been vaccinated and even if the wound looks minor. This page is general guidance, not a substitute for that in-person assessment.
Post-exposure treatment: the two scenarios
Post-exposure treatment (PEP) is always risk-assessed by a health professional, but UK (UKHSA) guidance sets out two very different pathways depending on your vaccination history:
✅ If you HAD the pre-exposure vaccine
- Only 2 booster doses of rabies vaccine — on day 0 and day 3–7.
- No rabies immunoglobulin needed.
- Applies even if you were vaccinated years ago.
- Vaccine doses are widely available, so treatment is simpler and faster.
⚠️ If you're immunosuppressed this doesn't apply — you may still need immunoglobulin and a longer 5-dose course (days 0, 3, 7, 14, 30). See the note below.
⚠️ If you did NOT have the vaccine
- A full course of 4 rabies vaccine doses — on days 0, 3, 7 and 21.
- For higher-risk exposures, also rabies immunoglobulin, as soon as possible.
- Immunoglobulin must be given early — it is not useful more than 7 days after the first vaccine dose.
- The immunoglobulin is the part that is hard to source abroad (see below).
⚠️ If you're immunosuppressed the course is longer — 5 doses (days 0, 3, 7, 14, 30), with immunoglobulin. See the note below.
Important: if you are immunosuppressed
The simpler “vaccinated” pathway above assumes a normal immune system. If you are immunosuppressed — for example due to certain medications or treatments, or a medical condition affecting your immune system — UK guidance is different: even if you completed a full pre-exposure rabies course, you may still need rabies immunoglobulin, together with a longer course of 5 vaccine doses (days 0, 3, 7, 14 and 30), depending on the risk assessment. This is because your immune response to the vaccine cannot be assumed to be adequate. Please tell us about any condition or medication that affects your immune system before you travel, so we can advise you properly.
Rabies immunoglobulin — and why it's the catch
Rabies immunoglobulin (RIG) is a preparation of ready-made antibodies that is infiltrated in and around the cleaned wound. It gives immediate, passive protection — neutralising the virus at the site of the bite during the 1–2 weeks it takes the vaccine to stimulate your own antibodies. Human rabies immunoglobulin (HRIG) is given at a dose of up to 20 IU/kg of body weight.
Crucially, immunoglobulin is only needed by people who were not vaccinated beforehand. And it is the single hardest part of rabies treatment to obtain:
- NaTHNaC (TravelHealthPro) reports that a study found 204 of 240 countries had limited or no access to rabies immunoglobulin.
- Even where it exists, supply is variable — you may have to travel to a major city, or even another country, to get it.
- Human RIG is in short supply worldwide; some places only stock equine (horse-derived) immunoglobulin.
- In the UK, HRIG is held centrally and only released by UKHSA after a formal risk assessment — it isn't stocked at every clinic.
The bottom line: an unvaccinated traveller bitten in a remote area can face a genuine struggle to get the immunoglobulin they need, in the narrow window where it still works.
The benefit of the pre-exposure rabies vaccine
Having the rabies vaccine before you travel changes everything if the worst happens:
- You no longer need immunoglobulin — removing the hardest, scarcest part of treatment entirely.
- Your post-exposure vaccine course drops from 4 doses to just 2.
- It buys you time and removes the urgency of hunting for RIG in a country where it may not exist.
- It is especially worthwhile for remote or long-stay travel, places with limited medical care, people with occupational animal contact, and children (who are bitten more often and may not report it).
The pre-exposure course is usually 3 doses over 3–4 weeks (an accelerated schedule may be possible). Importantly, pre-exposure vaccination does not mean you can ignore a bite — you still need the 2 booster doses promptly — but it makes safe treatment realistically achievable wherever you are.
Rabies FAQ
Rabies treatment — your questions answered
Yes — but it's much simpler. If you completed a pre-travel (pre-exposure) rabies course, after a bite, scratch or lick on broken skin you need only 2 booster doses of rabies vaccine (on day 0 and day 3–7) and you do NOT need rabies immunoglobulin. This holds even if you were vaccinated years ago. You must still wash the wound and seek medical care promptly. Note: this applies to people with a normal immune system — immunosuppressed travellers are managed differently (see below).
An unvaccinated person needs a full course of 4 rabies vaccine doses (on days 0, 3, 7 and 21) and, for higher-risk exposures, rabies immunoglobulin given as soon as possible. The immunoglobulin provides immediate protection while the vaccine takes 1–2 weeks to work — but it's the part of treatment that is hardest to obtain.
Rabies immunoglobulin (RIG) is a preparation of ready-made antibodies, infiltrated in and around the cleaned wound to neutralise the virus immediately while your body responds to the vaccine. It's only needed by people who haven't been vaccinated. The problem is supply: one study found 204 of 240 countries had limited or no access to rabies immunoglobulin. In many rabies-risk countries you may have to travel to a major city — or even another country — to find it, and human RIG is in short supply worldwide. In the UK it's released centrally by UKHSA after a risk assessment.
The rules are different if your immune system is suppressed — for example by certain medications or treatments, or a medical condition affecting immunity. Even if you completed a full pre-exposure rabies course, after a higher-risk exposure UK guidance is that you may still need rabies immunoglobulin, plus a longer course of 5 vaccine doses (days 0, 3, 7, 14 and 30), because your response to the vaccine can't be assumed to be adequate. Always tell us about any immune condition or medication before you travel so we can risk-assess and advise you correctly.
Wash the wound straight away — flush it under running water and clean thoroughly with soap for several minutes — then apply an antiseptic. Do not let the wound be stitched immediately. Seek medical advice urgently and start rabies post-exposure treatment abroad; don't wait until you get back to the UK. Keep a record (and photos) of any vaccine or immunoglobulin given.
Once symptoms develop, rabies is almost always fatal and there is no effective treatment. However, it is virtually 100% preventable if correct post-exposure treatment is started promptly after a bite. That is why prevention and prompt treatment matter so much.
