Thailand Travel Vaccinations
What vaccinations do I need for Thailand?
It depends on where you're going, for how long, and what you'll be doing. As a guide, UK travel health guidance groups the vaccinations for Thailand like this — your pharmacist will confirm exactly what you need at your consultation:
| Protects against | Who should consider it | Doses & schedule |
|---|---|---|
| Most travellers Hepatitis A | All travellers — spread through contaminated food and water, including in hotels and resorts. | 1 dose, ideally 2 weeks before travel. Booster at 6–12 months gives ~25 years' protection. |
| Most travellers Tetanus, diphtheria & polio | All travellers whose last booster was more than 10 years ago. | Single combined booster injection. |
| Most travellers Typhoid | Most travellers — especially if eating street food or visiting friends and family. | 1 injection, ideally 2 weeks before travel. Protects ~3 years. |
| Some trips Rabies | Longer stays, rural travel, cycling or running, working with animals — or anywhere contact with dogs, cats, monkeys or bats is likely. Treatment after a bite is hard to obtain in parts of Thailand. | Course of 3 injections over 21–28 days — book early. |
| Some trips Japanese encephalitis | Stays over a month, rural or rice-farming areas, or travel in the rainy season. | 2 injections, day 0 and day 28 (an accelerated 7-day schedule is possible). |
| Some trips Hepatitis B | Longer stays, healthcare work, new tattoos or piercings, or activities with a risk of blood contact. | 3 injections — an accelerated course over 21 days is available. |
| Some trips Dengue fever | Worth considering for Thailand, where dengue is widespread — especially longer, repeat or rainy-season trips. Available at our clinic whether or not you've had dengue before. | 2 doses, 3 months apart — book well ahead of travel. |
| Some trips Cholera | Aid workers or travel to areas with very limited sanitation. Not needed for typical tourism. | Oral vaccine: 2 doses, 1–6 weeks apart, completed at least 1 week before travel. |
A yellow fever certificate is not required when travelling to Thailand directly from the UK — it only applies if you arrive via a yellow fever risk country. Vaccine prices are kept up to date on our travel clinic price list.
Do I need malaria tablets for Thailand?
Most holidaymakers don't. Bangkok, Phuket, Koh Samui, Pattaya, Chiang Mai city and the main tourist centres are considered very low risk, and antimalarial tablets aren't usually advised there.
Some itineraries do. Rural, forested areas — particularly along the borders with Myanmar, Laos and Cambodia — carry a real malaria risk, and tablets may be recommended. The right choice depends on your exact route and dates.
Bring your itinerary to your consultation: we check it against current UK risk maps and, where cover is required, we explain the options and can supply your antimalarial tablets in the same visit. Tablets are started shortly before you enter the risk area and continued during and after your stay — we'll give you the exact schedule.
One more mosquito warning: dengue fever occurs across Thailand, including in cities. There are no tablets for dengue, but a dengue vaccination is available at our clinic — for all eligible travellers, whether or not you've had dengue before. Bite prevention (50% DEET repellent, covering up, sleeping under nets or in screened rooms) still matters for every traveller, as it also protects against other mosquito-borne infections.

The diseases explained
More detail on each illness you can be protected against before travelling to Thailand:
Hepatitis A
A viral liver infection spread through contaminated food and water — risk exists even for careful eaters staying in good hotels, which is why vaccination is advised for virtually all travellers to Thailand. Illness causes weeks of fatigue, nausea and jaundice. A single injection before travel protects, and a booster 6–12 months later extends protection for around 25 years.
Typhoid
A bacterial infection from contaminated food and water causing prolonged fever, headache and abdominal illness. Risk is highest for adventurous eaters and those visiting friends and relatives. One injection gives around three years' protection.
Tetanus, diphtheria & polio
These are covered by the UK childhood programme, but protection fades. Tetanus enters through cuts and animal scratches; diphtheria spreads person-to-person. Travellers whose last dose was over ten years ago need a single combined booster.
Rabies
Thailand has rabies in dogs, cats, monkeys and bats, and a lick, scratch or bite can transmit it. Once symptoms appear rabies is almost always fatal — and the treatment needed after a bite by an unvaccinated person is expensive and genuinely hard to obtain outside major Thai cities. Pre-travel vaccination is a course of three injections over 3–4 weeks, so this is the vaccine that most rewards booking early. It's particularly advised for stays over a month, rural travel, cycling and animal contact — but any traveller can be bitten, and around one in ten travellers to Southeast Asia reports an animal exposure.
Japanese encephalitis
A mosquito-borne viral brain infection found in rural Thailand, especially around rice paddies and pig farming, with risk peaking in and after the rainy season. Serious cases can be fatal or cause lasting neurological damage. Vaccination (two doses, usually four weeks apart) is advised for longer stays and rural itineraries.
Hepatitis B
A blood-borne viral liver infection transmitted through unprotected sex, tattoos, piercings, medical procedures and injuries. Advised for longer stays, healthcare workers and anyone whose plans carry a risk of blood contact. The standard course is three injections; an accelerated 21-day schedule suits imminent departures.
Cholera
A severe diarrhoeal illness from heavily contaminated water. Risk to conventional tourists is very low; the oral vaccine is reserved for aid workers and travel to areas with very poor sanitation.
Dengue fever
Dengue is the most common mosquito-borne infection in Thailand and, unlike malaria, the mosquitoes that carry it bite during the day and thrive in cities. A second infection can be more severe than the first. A dengue vaccination is available at our travel clinic — open to all eligible travellers, whether or not you've had dengue before — given as two doses three months apart, so it rewards booking early. Bite avoidance remains important even when vaccinated. Read more on our dengue fever page or ask at your consultation.
Where in Thailand are you going?
Bangkok & the cities
Food- and water-borne illness and dengue are the main risks; malaria tablets aren't usually needed. Hepatitis A, typhoid and up-to-date boosters cover most city breaks.
Islands & beaches
Phuket, Krabi, Koh Samui and the islands are low-risk for malaria. Think hepatitis A, typhoid, boosters — and rabies awareness around beach dogs and monkeys.
The north & trekking
Chiang Mai, Chiang Rai and hill-trekking routes raise the case for rabies and Japanese encephalitis cover, especially on longer or rural itineraries.
Border regions
Rural areas near the Myanmar, Laos and Cambodian borders are where malaria tablets come into play — bring your route and we'll map it against current risk data.
Planning your timing
Most UK travellers visit Thailand between November and March, in the cool, dry season. If that's you, the ideal time to book your travel consultation is September to January — 6 to 8 weeks before you fly. Rainy-season travel (roughly May to October) increases mosquito activity, which strengthens the case for Japanese encephalitis cover on rural trips and makes bite prevention even more important.
Everyday health essentials for Thailand
Food & water: drink bottled or boiled water, avoid ice of unknown origin, choose freshly cooked food served hot, and peel fruit yourself. Bites: 50% DEET repellent, cover arms and legs at dawn and dusk, sleep under nets or in screened rooms. Sun & heat: high-SPF sunscreen, hydration, and shade in the middle of the day. If you're unwell after you return — especially with fever — see a doctor promptly and mention your travel history. Our pharmacists can advise on travel first-aid kits, oral rehydration and stomach remedies at your appointment.
Frequently asked questions
How far in advance should I book my Thailand vaccinations?
Ideally 6–8 weeks before travel, because the rabies and Japanese encephalitis courses take 3–4 weeks to complete. Flying sooner? Single-dose protection against hepatitis A and typhoid works at shorter notice, and accelerated schedules exist — book the earliest appointment you can and we'll prioritise.
Do I need malaria tablets for Bangkok, Phuket or Koh Samui?
No — the main cities and tourist islands are considered very low risk. Tablets only come into consideration for rural border regions and some forested areas. We confirm this against current UK guidance at your consultation.
Is there a dengue fever vaccine?
Yes — our clinic offers a dengue vaccination, available to all eligible travellers whether or not you've had dengue before. The course is two doses given three months apart, so book well ahead of your trip. See our dengue fever page for details.
How much do travel vaccinations cost?
You only pay for the vaccinations you actually need, agreed at your consultation. Current prices are on our travel clinic price list.
Can my family be vaccinated at the same appointment?
Yes — we routinely see couples and families together. Book one slot and mention the number of travellers, or call us on 01276 21002 and we'll arrange it.
Do I need a yellow fever certificate for Thailand?
Not if you're travelling directly from the UK. A certificate is only required if you arrive from a yellow fever risk country. If your itinerary includes one, see our yellow fever page.
What should I bring to my appointment?
Your itinerary (destinations, dates, rural stops), your vaccination history if you have it, and a note of any medicines you take or allergies. That's all we need to build your personalised plan.
