That is not the same as nothing being worth having, and the gap between the two is where the bad trips happen. - Author: Somchai Jaidee - Tags: Practicalities I spent forty minutes in a [clinic](https://easythailandvisa.com/thailand-hospitals-and-clinics-for-tourists/) in Bangkok being vaccinated against things I did not need, because I had not worked out the difference between what a country requires and what a country recommends, and nobody had explained it to me. It is a genuinely important distinction, and it is not the one most travel health pages make. Here is the actual shape of it. Last verified 24 July 2026. ## What Thailand requires to let you in: almost nothing **There is no vaccination requirement for entry for almost any nationality,** and no health screening, and no certificate of any kind unless you are arriving from a country with a yellow fever risk, in which case a yellow fever certificate is required and it is the only one that matters. **That is the entire entry requirement, and it is worth saying plainly** because "check the vaccination requirements" is advice that makes a lot of people anxious about a country that does not require anything. ## What is worth having anyway **Hepatitis A is the one to have.** It is cheap, it is very effective, it is not something most adults have as a routine vaccine, and the country has a genuine food and water hygiene gradient that runs from excellent in the cities to genuinely variable in small rural restaurants. This is the one I would insist on. **Tetanus, up to date.** Nothing to do with Thailand specifically, but injuries are the most common thing that happens to travellers and an out-of-date tetanus is a genuine, stupid, entirely avoidable problem. **Typhoid, depending on where you are going.** If you are in cities, on the tourist circuit, in hotels and restaurants, this is a marginal call. If you are going to rural areas, small restaurants and [street food](https://easythailandvisa.com/street-food-safety-in-thailand/) as a way of life rather than a holiday, it is worth it. **Rabies, as a considered decision rather than a routine one.** This is the one that requires thought rather than a reflex, and it is covered properly below. **Japanese encephalitis, for a specific trip.** This one is genuinely under-considered by travellers and it is worth understanding: the risk is rural and agricultural rather than urban, it is about being in the countryside for weeks rather than days, and it is a serious disease with a real mortality rate. A month camping in rural Thailand is a different proposition from a fortnight in Bangkok and the beach. **And the routine childhood series,** which is not exciting but which people born in the last forty-five years are frequently not fully up to date, and which is a free-standing good idea regardless of where you are going. ## The rabies decision, which is the one that actually needs a conversation **Thailand has a genuinely significant rabies problem,** and most cases come from dog and [monkey](https://easythailandvisa.com/thailand-temple-monkeys-rabies-what-to-do/) bites rather than from anything exotic. Stray dogs in particular. It is a real public health issue in the country and not a traveller-specific one. **The practical reality is that if you are bitten or scratched and you get prompt, thorough wound washing and post-exposure treatment, you will be fine.** The deaths occur in people who were bitten and did not get treated, which in most cases means rural, remote, or people who could not access care. **So the question is not "am I going to get rabies" and the practical mitigations are unglamorous:** do not touch stray dogs, do not touch monkeys, do not pick up bats, and if you are scratched or bitten by any mammal, wash the wound with soap and running water for a long time and go to a clinic that same day rather than in the morning. **And be careful about the one specific case that catches Western travellers, which is monkeys.** They are aggressive around food, they bite without provocation, and a monkey scratch is treated as a bite for rabies purposes. Do not feed them, do not approach them, and do not hold your phone out to get a photograph. **For most tourists on a two-week trip, the rabies vaccine is not necessary.** For anyone spending a month or more in rural areas, working with animals, or doing a lot of trekking, it is a genuinely reasonable thing to have. ## Dengue, which is the one that actually matters **And this is the health point that deserves the most attention, because it is the one that will actually affect your trip and almost nobody prepares for it.** **Dengue is carried by the daytime-biting mosquito that everybody ignores,** which is the same mosquito that carries chikungunya and Zika, and it is present across the country including in the cities, not only in the jungle. **There is no routinely recommended traveller vaccine for dengue**, and understanding why matters: the available vaccines are approved for specific populations with a documented history of infection, and are not generally recommended for travellers without one. So this is not something you solve with a jab. **You solve it with three boring things.** Repellent containing DEET or picaridin, applied rather than just carried. Sleeve and trouser coverage in daylight hours, which people find absurd until they have watched a mosquito land on an arm. And a room with [air conditioning](https://easythailandvisa.com/thailand-hotel-basics-ac-hot-water-wifi/) or a working fan, because these mosquitoes are weak fliers and a closed window genuinely works. **And if you get it, it is usually manageable and it is not something to be catastrophised about**, but it is genuinely miserable, the fever and the aches last several days, and recovery takes longer than the illness does. Plenty of people are fine and plenty of people lose a week of a trip to it. ## Malaria, and where it actually is **The honest answer is that for most of the country, the malaria risk is low enough to be a conversation rather than a requirement.** Bangkok, the Gulf coast, Phuket, the main tourist circuit, the northern cities: not a routine concern. **The real risk is deep in forested and rural border areas,** particularly in the western and southern borders, and in remote jungle. That is a genuine category of trip and it requires a proper consultation rather than an internet answer. **Talking to a travel clinic is worth doing.** Not because most people need much, but because the advice depends entirely on the specific trip, and the cost of a consultation is trivial relative to the trip. ## What to do before you go **Six to eight weeks out is the normal window,** and some things need multiple doses, which is the actual reason to go early rather than the day before. **Bring your records.** A paper or phone record of what you have had and when. Handlers at immigration and at clinics will not be able to tell you and the only version that exists is the one you brought. **And take a small kit that is not about vaccines at all:** rehydration salts, anti-diarrhoeals for genuine emergencies, antihistamines, plasters, and any prescription you use regularly with enough supply for a few days of delay. ## The honest summary **Thailand requires nothing, and almost every traveller should have three things: hepatitis A, an up-to-date tetanus, and a considered answer about rabies based on how rural the trip is.** Everything else is a judgement call about a specific trip, and the one preparation that pays for itself every single time is the boring mosquito defence, because dengue is the illness that will actually cost you the week. **More on this** - [What Happens If Your Arrival Card Does Not Match Your Passport](https://easythailandvisa.com/arrival-card-mismatch-immigration/) - [Your Bank Called to Say the Card in Thailand Was Captured,](https://easythailandvisa.com/atm-and-card-fraud-in-thailand/) - [Bangkok Has a Second River and Almost Nobody Gets on It](https://easythailandvisa.com/bangkok-klongs-canal-boat-hidden-city/) - [The Post Office Will Hold Your Passport If You Ask Nicely](https://easythailandvisa.com/thailand-postal-parcel-sending-home/)
