Thailand Travel Vaccines: What You Need Depends on Where You’re Going

The flights are booked. The itinerary is taking shape. Now comes the part most people put off, working out which vaccines you actually need for Thailand and whether there’s still time to get them done.

At Ealing Travel Clinic on 30 Northfield Avenue, we help London travellers sort their Thailand travel vaccines every week. Some come in with six weeks to spare and leave with everything done in one appointment. Others call four days before departure wondering what’s still possible. Both situations are manageable. The earlier you come in, the more options are open to you.

Thailand is a destination where your itinerary matters more than almost anywhere else. A week at a Phuket resort is a very different health picture from two weeks trekking through the valleys north of Chiang Mai. We assess each trip individually — we won’t recommend vaccines that aren’t relevant to your specific route, and we won’t let you miss ones that matter.

Here’s the full picture, the vaccines every Thailand traveller needs, and the ones that depend on where you’re actually going.

The Vaccines Every Thailand Traveller Should Have

Whatever your itinerary — Bangkok city break, island holiday, VFR trip, or business travel — three vaccines form the recommended foundation for any journey to Thailand.

Hepatitis A — £45 per dose

Transmitted through contaminated food and water, and present across Thailand regardless of your accommodation standard. The virus can reach kitchen staff at five-star hotels just as readily as it travels through street food.

• Single dose before travel: around 95% protection within two weeks
• Second dose at 6–12 months after your return: covers you for 20+ years
• One dose before travel is sufficient protection for the trip

Typhoid — £30

Food and water-borne, and the risk exists across Thailand including at higher-end restaurants. The risk comes from the food supply chain as a whole, not just the places that look less clean.

• Single injectable dose
• Protection develops within one to two weeks
• Lasts three years

Diphtheria, Tetanus and Polio (DTP) booster — £30

Worth reviewing before any international travel. Tetanus risk is real anywhere cuts or wounds are possible, and most UK adults are due a booster every ten years.

• One dose if you haven’t had it in the last decade
• If you’ve had it within ten years, you’re already covered
• One of the most overlooked vaccines we see across all destinations

Do You Need Malaria Tablets for Thailand?

The majority of travellers to Thailand do not need malaria tablets. This surprises a lot of people, partly because Thailand is in Southeast Asia and partly because travel health advice can sometimes present the region as uniformly high-risk.

The reality is more precise: malaria risk in Thailand is highly area-specific, and for the most popular tourist destinations, the risk is either very low or absent altogether.

Bangkok carries no malaria risk. Neither does Phuket, Koh Samui, Koh Phangan, Koh Tao, Koh Lanta, Koh Phi Phi, Pattaya, Hua Hin, or Chiang Mai city centre.

If your trip is based around these places  which covers the vast majority of package holidays, beach breaks, and independent travel,  you don’t need antimalarial medication. We won’t prescribe tablets you don’t need.

Sources: NaTHNaC TravelHealthPro (December 2025), CDC Yellow Book 2026. Travellers with significantly reduced immunity, pregnant women, infants, or those over 70 should discuss their individual risk with Sachin at consultation even for the lower-risk areas above.

If you’re travelling near Thailand’s borders, you may need antimalarials.

The higher-risk areas are the forested, rural zones bordering Myanmar, Cambodia, and Laos — specifically the provinces of Tak, Mae Hong Son, Chiang Rai (border zones), Kanchanaburi, and Ranong. If your itinerary includes any of these areas, bring it to your consultation.

One important restriction applies here: mefloquine (Lariam) is not suitable for the Myanmar or Cambodia border regions due to documented drug resistance. The recommended options are:

• Atovaquone/proguanil (Malarone) — £2.50 per tablet
• Doxycycline — £0.45 per capsule

Note that mefloquine was in short supply in the UK until the end of March 2026 (NaTHNaC 2026), which is an additional reason to discuss alternatives at your appointment.

Dengue is a different conversation entirely.

It’s present throughout Thailand — not just border areas — and 51,795 cases were recorded across the country in 2025, with 46 deaths (NaTHNaC, October 2025). There is no universally appropriate vaccine for most travellers. Protection comes down to behaviour:

• DEET-based repellent, applied during daylight hours as well as at dusk
• Long sleeves and trousers at dawn and dusk
• Air-conditioned or well-screened accommodation where possible

Vaccines That Depend on Your Itinerary

What Your Trip Type Means for Your Vaccines

Thailand is not one destination — it’s several, with very different health profiles. Rather than a generic list, here’s how vaccine recommendations typically break down by trip type. These are starting points; your consultation with Sachin will refine the list based on your actual itinerary.

Families visiting relatives in Thailand often underestimate their own risk profile. VFR travellers — visiting friends and relatives — tend to stay longer, eat more local food, spend more time in rural areas, and feel less urgency around pre-travel health because Thailand feels familiar. In practice, the exposure risk is frequently higher for this group, not lower.

Children should be assessed for rabies vaccination regardless of the overall itinerary. They are the age group most likely to approach animals and least likely to report a minor scratch that didn’t seem significant.

One group that frequently travels through our clinic is longer-stay travellers — retirees, people on sabbatical, or those with family roots in Southeast Asia. For anyone spending more than a month in Thailand, we recommend reviewing the full vaccine list including Hepatitis B, Rabies, and JE rather than defaulting to the beach-holiday minimum.

Current Health Alerts for Thailand — As of March 2026

None of these alerts should put you off travelling to Thailand, but they do reinforce the value of a proper pre-travel consultation before you go.

When to Book Your Thailand Vaccines

The timing question is one we’re asked constantly. The honest answer is that six to eight weeks before travel is the ideal window, and three weeks before is the practical minimum for most vaccines.

1. Book your consultation as soon as your trip is confirmed.  Six to eight weeks before departure gives you the most flexibility, particularly if Japanese Encephalitis is likely on your list. Book online or call 0208 567 0982.
2. Bring your full itinerary and any vaccination records you have.  The more specific you can be about where you’re going, the more precise our recommendations will be.
3. At the consultation, we review your trip in detail.  Destinations, activities, accommodation type, trip duration, any relevant health history, and any vaccines you’ve had before.
4. Most vaccines are given the same day as the consultation.  If Japanese Encephalitis is recommended, we plan a dose schedule to fit your travel date.

We give you a full record of vaccines given and any follow-up doses.  Keep this with your travel documents.

For a typical beach holiday — Hepatitis A, Typhoid, and DTP booster — the total is £105. Adding Japanese Encephalitis for a Chiang Mai trip brings it to £305. A full adventure package including Rabies is £485. Chikungunya at £175 can be added to any package where northern Thailand or outdoor rural activity is involved.
