Quick Answer
Do I need vaccinations for Thailand?
No mandatory vaccines are required to enter Thailand. However, travel health professionals recommend ensuring Hepatitis A and Typhoid vaccines are current, plus up-to-date routine vaccinations (MMR, Tdap, flu). For longer stays or rural and border region travel, Hepatitis B, Japanese Encephalitis, and Rabies are also recommended.
Recommended Vaccines
Hepatitis A: Transmitted through contaminated food and water. Recommended for all travellers. Two doses provide lifelong protection.
Typhoid: Also food and water borne. Recommended for most travellers, especially those eating street food or visiting rural areas. Available as an injectable or oral vaccine.
Hepatitis B: Transmitted through blood and sexual contact. Recommended for longer stays, healthcare workers, and those with potential exposure risk.
Japanese Encephalitis: Mosquito-borne viral infection. Risk is low in cities but higher in rural farming areas with pigs and birds. Recommended for stays over 1 month, extensive rural travel, or during monsoon season.
Rabies: Stray dogs and monkeys in Thailand can carry rabies. Pre-exposure vaccination simplifies post-exposure treatment significantly — recommended for long stays, those working with animals, or travellers in areas far from quality medical care.

Routine Vaccinations to Check
Use your Thailand trip as an opportunity to confirm your routine vaccinations are current: MMR (measles, mumps, rubella), Tdap (tetanus, diphtheria, pertussis), seasonal influenza, and COVID-19 boosters. These protect against diseases that can be contracted anywhere in the world, and Thailand's crowded tourist environments — airports, temples, night markets — increase exposure risk.
Traveller's Diarrhoea
There is no vaccine for the most common travel illness. Prevention: wash hands frequently, eat food cooked fresh and hot, avoid tap water and raw salads washed in tap water, and be selective about ice. Bring oral rehydration sachets and consult your doctor about carrying an antibiotic prescription for severe cases.
