> As of July 2026 Thailand requires no entry vaccine except a yellow fever certificate from risk countries; CDC and NaTHNaC recommend hepatitis A and typhoid.

As of July 2026, Thailand does not require proof of any vaccine for most visitors to enter. The one exception is yellow fever: travelers arriving from a country where yellow fever spreads, or after a long airport layover in one, must carry an international vaccination certificate. Everything else is a recommendation, not an entry rule. The U.S. Centers for Disease Control and Prevention (CDC) and the UK's TravelHealthPro service (run by NaTHNaC) both point most travelers toward hepatitis A and typhoid, with hepatitis B often added, and both suggest booking a travel health visit four to six weeks before you fly.

This guide is general information for international leisure and business travelers, not medical advice, and it reflects CDC and UK NaTHNaC guidance current as of July 2026. Your own list depends on your itinerary, health history, and past shots, so treat what follows as a starting point to bring to a clinic, not a prescription. It does not cover children's schedules, pregnancy, or long-term work relocation in detail.

## Do you need any vaccine to enter Thailand?

For most travelers, no. Thailand has no yellow fever risk of its own, but it enforces the international certificate requirement. The CDC and TravelHealthPro both note that a yellow fever certificate is required for travelers aged nine months and older who arrive from a country with yellow fever transmission, or who spent more than 12 hours transiting an airport in such a country. Those risk countries sit mainly in parts of sub-Saharan Africa and tropical South America. If your trip starts in North America, Europe, or elsewhere in Asia and you fly straight to Thailand, this rule usually will not apply to you.

If it does apply, carry the yellow International Certificate of Vaccination or Prophylaxis, often just called the yellow card. The World Health Organization amended its rules so that a yellow fever certificate is valid for the life of the person vaccinated, which means an old certificate still counts. Thai entry regulations allow officials to vaccinate and quarantine arrivals who cannot show a required certificate, so check your route before you go.

## Which vaccines are recommended for most travelers?

Hepatitis A and typhoid come first. Both spread through contaminated food and water, and the CDC recommends them for most travelers to Thailand because hygiene varies once you eat outside major hotels and restaurants. TravelHealthPro describes the hepatitis A vaccine as recommended for all previously unvaccinated travelers, and it flags typhoid for people whose plans raise their risk, such as those visiting friends or relatives or heading to areas with poor sanitation.

Before adding anything less common, make sure your routine vaccines are current. The CDC lists measles-mumps-rubella (MMR), tetanus-diphtheria-pertussis (Tdap), polio, seasonal influenza, and COVID-19 among the routine shots to keep up to date. Hepatitis B, which spreads through blood and body fluids, is also worth a conversation: TravelHealthPro says it can be considered for any traveler and is advised for longer stays, healthcare work, or higher-risk activities. The table below groups the common vaccines by who usually needs them.

| Vaccine | Who it is usually for | Cited by |
| --- | --- | --- |
| Hepatitis A | Most travelers | CDC, NaTHNaC |
| Typhoid | Most travelers; higher risk in rural areas | CDC, NaTHNaC |
| Hepatitis B | Longer stays, higher-risk activities | CDC, NaTHNaC |
| Japanese encephalitis | Stays of a month or more, rural trips | CDC, NaTHNaC |
| Rabies | Long stays, remote areas, animal work | CDC, NaTHNaC |

No vaccine is required just to enter Thailand — the shots here are recommended, grouped into routine and travel-specific.

## Vaccines for longer stays and rural trips

Two vaccines depend heavily on how long you stay and where you go. Japanese encephalitis is a mosquito-borne infection concentrated in rural, agricultural areas. Both the CDC and TravelHealthPro suggest considering the vaccine for travelers spending a month or longer during the transmission season, for frequent visitors, and for anyone with an open-ended rural itinerary. A short city stay in Bangkok does not call for it.

Rabies is the other. Thai government campaigns to vaccinate cats and dogs have lowered the risk, the CDC notes, but stray animals still carry it. TravelHealthPro recommends pre-exposure rabies vaccination for stays over one month, for travel to remote areas without quick access to medical care, and for people who handle animals. The CDC adds that rabies vaccine and immune globulin are available in all provincial and most district hospitals in Thailand, so a bite still needs prompt treatment even if you were vaccinated beforehand.

## What about malaria and dengue?

Neither is handled by a shot you would get for a typical trip. Malaria in Thailand is limited to specific rural, forested zones. The CDC points to the areas bordering Myanmar and Cambodia and the far-southern provinces along the Malaysia border, and for those areas it lists atovaquone-proguanil, doxycycline, or tafenoquine as preventive drug options. For Bangkok, Chiang Mai, and Phuket, the CDC recommends mosquito-bite avoidance alone rather than preventive pills.

Dengue has no vaccine in standard traveler advice, and the CDC's guidance is direct: prevent it by avoiding mosquito bites. Dengue-carrying mosquitoes bite during the day and become more active in the rainy season, which is one reason it helps to know [when Thailand's rains and peak seasons fall](https://foreignerguide.com/articles/when-not-to-visit-thailand-rain-smoke-and-peak-season-crowds.html) before you book. Repellent with DEET or picaridin, long sleeves at dusk, and air-conditioned or screened rooms do more here than any pill.

## How far ahead should you plan?

Book a travel health appointment four to six weeks before departure. The CDC uses that window because some vaccines need more than one dose or take time to become effective, and a clinician can match the list to your route. A few steps make the visit smoother:

- Bring a record of past vaccinations so you only get what you actually need.
- Write down your itinerary, especially any rural stays or border regions, since malaria and Japanese encephalitis advice hinges on where you go.
- Ask about routine boosters, such as tetanus, at the same visit.
- Keep your certificates together, including any yellow fever card, in case immigration or a future trip asks for them.

If you left it late, going is still worth it. Even a shot a week or two before travel offers some protection, and a clinician can advise on what remains useful. For the official country pages, the [CDC's Thailand travelers' health page](https://wwwnc.cdc.gov/travel/destinations/traveler/none/thailand) and the UK's [TravelHealthPro Thailand guide](https://travelhealthpro.org.uk/country/221/thailand) are the two references that clinics themselves lean on.
