Rabies Vaccination in Bangkok: Post-Exposure Prophylaxis, Pre-Exposure and Schedules
How Doctor Bangkok delivers rabies post-exposure prophylaxis the way WHO recommends, fast.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok
Rabies is a viral infection of the central nervous system that is almost always fatal once symptoms appear but fully preventable with prompt post-exposure prophylaxis. Bangkok is a rabies-endemic setting. At Doctor Bangkok we assess bite category, wash the wound properly, start the WHO-recommended vaccine schedule without delay, give rabies immunoglobulin when indicated for category III exposures, and schedule the full course. Starting the vaccine within 24 hours of exposure is the goal, but it is never too late to start if symptoms have not appeared.
From the clinic: Rabies is the infection you do not gamble with. In Thailand, stray dog and cat bites are common, monkey bites happen around temples and tourist sites, and bat exposure is less common but significant. Every bite needs a decision within hours: was the exposure category II or III, does the patient need vaccine alone or vaccine plus immunoglobulin, and is a previous vaccination history going to change the schedule. These are the questions I work through in the first few minutes of the visit, because delay is the only mistake that matters with rabies.
Exposure categories and what they mean
WHO defines three exposure categories. Category I is touching or feeding animals with intact skin and needs no prophylaxis. Category II is minor scratches or abrasions without bleeding and needs wound washing plus vaccine. Category III is single or multiple transdermal bites, scratches with bleeding, contamination of mucous membranes with saliva, or any bat exposure, and needs wound washing, vaccine, and rabies immunoglobulin. Categorising the exposure correctly is the first job, because it drives everything that follows. When in doubt we treat at the higher category.
| Category II exposure | Category III exposure |
|---|---|
| Minor scratch, no bleeding | Transdermal bite, bleeding |
| Abrasion from paw | Deep bite puncture |
| No mucous membrane contact | Saliva to mucous membrane |
| No bat exposure | Any bat exposure |
| Wash wound, vaccine only | Wash, vaccine plus immunoglobulin |
| Same-day treatment | Same-day treatment, urgent |
Wound washing is the first treatment
Immediate and thorough wound washing with soap and water for at least 15 minutes is the first rabies treatment and the one most often skipped. It reduces viral load at the wound site and is effective even without any soap available, though soap helps. After washing we irrigate with povidone-iodine or an alcohol-based antiseptic. Do not suture the wound if possible, particularly for face or hand bites, because closure can trap virus; if closure is essential, do it after local immunoglobulin infiltration. Our wound dressing service covers the non-rabies aspects.
Vaccine schedules and immunoglobulin
The WHO-recommended intramuscular post-exposure schedule for previously unvaccinated patients is 4 doses on days 0, 3, 7 and 14 to 28 (Essen regimen) or 4 doses given at 2 sites on days 0, 3 and 7 (updated Thai Red Cross intradermal regimen, which is faster and uses less vaccine). For previously vaccinated patients, 2 doses on days 0 and 3 are sufficient. Rabies immunoglobulin (human or equine) is given once, with as much as possible infiltrated around the wound and the remainder intramuscularly, for category III exposures in previously unvaccinated patients. Tetanus prophylaxis and antibiotic cover for the bite itself are given at the same visit.
When to see a doctor
Seek same-day care after any bite, scratch or mucous membrane contact with a mammal in Thailand, any bat exposure regardless of apparent injury, and any wound from an animal you cannot reliably confirm is rabies-vaccinated. Seek emergency care for multiple deep bites, bites to the face or hands, and any signs of wound infection (spreading redness, pus, fever) in the days after a bite. Do not wait for symptoms of rabies. Once central nervous system symptoms appear, rabies is fatal; the window to act is before any symptoms, which is usually weeks but can be shorter for head and neck bites. Our page on animal bites covers the acute visit in detail.
Red flag: If red-flag symptoms appear, do not wait. Book same-day or present to the nearest emergency department as described above.
Prevention and early detection
Pre-exposure rabies vaccination is recommended by WHO for travellers to rabies-endemic areas with extended stays, outdoor activity, or limited access to medical care, and for long-term residents. The pre-exposure schedule is 2 doses on days 0 and 7, and it simplifies post-exposure management because immunoglobulin is no longer needed and the post-exposure course shortens to 2 vaccine doses. Avoid contact with street animals, do not feed or approach monkeys around temples, and supervise children carefully in areas with stray dogs. If a pet is acting strangely, assume rabies until proven otherwise and seek medical advice for any exposure.
Summary
Rabies prevention is about urgency and completeness. The wound gets washed for 15 minutes, the exposure gets categorised correctly, the vaccine course is started the same day and completed on schedule, and immunoglobulin is given for category III exposures in unvaccinated patients. Doctor Bangkok keeps the modern WHO schedules in stock and starts treatment on walk-in, with no delay. As Dr. Pitsuwan puts it: “Rabies is the disease where the right action on day zero is what decides whether you live.” We serve tourists, expats and residents from our Sukhumvit clinic and as part of our wider 24/7 medical services.
Frequently asked questions
How quickly do I need to start rabies vaccination?
Ideally within 24 hours of exposure, but post-exposure prophylaxis is effective at any point before symptoms appear. Do not delay, do not give up if you are a few days late.
How many vaccine doses are needed?
For previously unvaccinated patients, 4 doses over 2 to 4 weeks. For previously vaccinated patients, 2 doses. Schedules vary by route and regimen; we confirm the right one at the visit.
Do I need rabies immunoglobulin?
Yes, for category III exposures in previously unvaccinated patients. Not needed for category II, or for patients with a complete prior rabies vaccination course.
What is pre-exposure rabies vaccination?
A 2-dose course given before any exposure, usually for travellers staying long in endemic areas. It simplifies post-exposure care and removes the need for immunoglobulin.
Can rabies be transmitted from cats or monkeys?
Yes. Any mammal can carry rabies. Dog, cat, monkey and bat bites are the commonest exposures treated in Bangkok.
What if I cannot find the animal to check it?
Treat as a suspected exposure and start post-exposure prophylaxis. In endemic Thailand we do not wait for animal observation to begin treatment.
