Vaccinations & travel health in Thailand — what you actually need.

The short version

Be current on the basics, take rabies seriously

You do not need a wall of injections to live in Thailand, and no vaccine is legally required for entry from most countries (a yellow-fever certificate is only asked of travellers arriving from a yellow-fever zone). What a travel-medicine doctor will usually suggest for a long stay is to be up to date on your routine vaccines, add hepatitis A and typhoid because they are food- and water-borne, consider hepatitis B and Japanese encephalitis depending on how and where you live, and — the one that genuinely matters here — think hard about rabies. None of this is urgent enough to delay a move; most expats simply book a single travel-clinic appointment in their home country or in Bangkok and sort it in one or two visits.

Routine vaccines to keep current

Tetanus, MMR, flu and COVID

Before anything Thailand-specific, make sure your everyday vaccinations are current: tetanus-diphtheria (a booster every ten years, and worth having given how often a scooter graze or a cut happens here), measles-mumps-rubella, and chickenpox if you have never had it or the disease. Influenza circulates year-round in Thailand with a strong rainy-season peak, so an annual flu shot is genuinely useful rather than seasonal-at-home logic, and it is cheap and widely available. Keep your COVID-19 vaccination reasonably up to date too. These routine ones do most of the real-world protecting.

Hepatitis A and typhoid — the food-and-water pair

The two most worth getting

Hepatitis A and typhoid both spread through contaminated food and water, which makes them the most relevant travel vaccines for anyone eating widely at street stalls and local restaurants — which is to say, everyone who actually enjoys living here. Hepatitis A is a single shot with a booster six to twelve months later that then protects for decades. Typhoid is one injection (good for about three years) or an oral course. Neither replaces sensible habits — drink filtered or bottled water and be a little choosier with raw shellfish and cut fruit that has been sitting out — but together they remove the two infections most likely to ruin a month.

Hepatitis B

Worth it for longer stays

Hepatitis B spreads through blood and bodily fluids — medical and dental procedures, tattoos and piercings, and sexual contact — so the longer you stay and the more embedded your life becomes, the more sense the vaccine makes. Many people from countries with childhood Hep B programmes are already covered; if you are not, it is a three-dose course over six months (an accelerated schedule exists if you are short on time). It is a quietly sensible one for long-stay residents who may use local clinics, dentists or tattoo studios.

Rabies — the one to take seriously

Thailand has rabies; plan ahead

This is the vaccine conversation that matters most in Thailand. Rabies is present in the country's large stray-dog and cat population — and in monkeys at temples and tourist spots — and once symptoms appear it is almost always fatal, so it is treated as an absolute. Pre-exposure vaccination (two doses about a week apart on the current schedule) does not make you immune; what it does is buy time and simplify treatment if you are bitten or scratched, removing the need for rabies immunoglobulin, which can be hard to source. It is well worth considering if you will be here long-term, cycle or run outdoors, live near strays, or have children, who are both more likely to approach animals and less likely to report a small scratch.

If an animal bites or scratches you

Wash, then go — even if vaccinated

Treat any bite, scratch or even a lick on broken skin from a dog, cat or monkey as a potential rabies exposure. Immediately wash the wound with soap and running water for a full fifteen minutes, apply antiseptic, and get to a hospital the same day — do not wait. If you had the pre-exposure course you will need two booster doses (days 0 and 3) and no immunoglobulin; if you did not, you need a full post-exposure course plus rabies immunoglobulin. Bangkok's Queen Saovabha Memorial Institute (the Thai Red Cross snake farm in Pathum Wan) is the national centre for rabies and is the gold-standard place to be treated, and every major hospital handles post-exposure care routinely. This is one situation where speed beats everything.

Japanese encephalitis

Mainly for rural or very long stays

Japanese encephalitis is a mosquito-borne brain infection linked to rural rice-farming and pig-rearing areas, and the risk to a city-based expat in Bangkok or on the islands is very low. It becomes worth discussing if you will spend a lot of time in the countryside, work in agricultural areas, or settle long-term upcountry, especially in the rainy season. The vaccine is a two-dose course. For most urban residents a travel doctor will weigh it against your actual lifestyle rather than recommend it by default.

Dengue and malaria — know the difference

Dengue: prevention, not a routine shot. Malaria: border forests only

Two mosquito-borne illnesses people worry about are handled differently from the vaccines above. Dengue is common and circulates nationwide, but the day-to-day defence is bite prevention rather than a routine jab; a dengue vaccine (Qdenga) is available privately in Thailand and may suit some long-term residents, but whether it fits you depends on your prior dengue history, so it is a doctor-led decision. Malaria, by contrast, has been pushed out of Bangkok, the beaches and the islands — routine anti-malarial tablets are not recommended for normal life and only come up for overnight trips into remote forest along the Myanmar, Cambodia or Laos borders. Our mosquitoes and dengue guide covers the prevention side in detail.

Where to get vaccinated in Bangkok

Travel clinics and hospital vaccine centres

You do not need to arrive fully vaccinated — Bangkok is an easy, affordable place to sort this out, often at a fraction of Western prices. The Thai Travel Clinic at the Hospital for Tropical Diseases (Mahidol University, Ratchathewi) is a respected, budget-friendly specialist option; the Queen Saovabha Memorial Institute (Thai Red Cross) is the go-to for rabies and snakebite; and the international hospitals — Bumrungrad, Samitivej, BNH, MedPark and Bangkok Hospital — all run travel-vaccine and health-screening services with English-speaking staff. Bring any vaccination records you have (a yellow card or ICVP if you hold one) so a doctor can see what you have already had and only give what you actually need.

A simple plan most expats follow

One appointment, a short follow-up

Put together, the typical approach is light: book one travel-clinic appointment — at home before you fly or in Bangkok after you land — and let a doctor tailor it to your plans. Most people end up topping up tetanus and flu, getting hepatitis A and typhoid, adding rabies pre-exposure if they are staying a while, and considering hepatitis B and Japanese encephalitis based on lifestyle. A couple of these need a second dose weeks or months later, which you can do locally. Keep a record of what you have had, and you are set — free to enjoy the food, the temples and the strays from a sensible distance.
