What Vaccines Do You Need for Thailand?
Based on current CDC guidelines. Thailand requires more vaccines than typical beach destinations due to diverse health risks across regions.
Hepatitis A
Strongly RecommendedEssential for ALL travelers to Thailand. Protects against contaminated food and water — a significant risk when enjoying Thai street food and local cuisine. One dose protects your trip; a booster provides lifetime immunity.
Typhoid
Strongly RecommendedHighly recommended for Thailand where street food is a major attraction. Bacterial infection spread through contaminated food and water. Available as injection (single dose) or oral capsules (4 doses over a week).
Hepatitis B
RecommendedSpread through blood and bodily fluids. Recommended for travelers who might receive medical or dental care, get tattoos or piercings, have sexual contact, or stay longer than 6 months.
Japanese Encephalitis
RecommendedMosquito-borne virus causing brain inflammation. Recommended if spending extended time (1+ month) in rural areas, visiting during monsoon season, or staying overnight in agricultural regions. Risk is low in major cities.
Rabies
RecommendedStrongly recommended for Thailand — stray dogs and monkeys are extremely common, especially near temples and tourist areas. Pre-exposure vaccination gives you critical extra time to reach medical care if bitten.
Cholera (Dukoral)
RecommendedConsider if visiting areas with active cholera outbreaks, doing humanitarian work, or traveling to remote regions with limited access to clean water. Also provides some protection against traveler's diarrhea.
Routine Vaccines (Tdap, MMR, Polio)
RecommendedEnsure your routine vaccines are up to date before traveling to Southeast Asia. Many Canadians are overdue for their Tdap booster. We'll verify your immunization records during consultation.
COVID-19
RecommendedUpdated boosters recommended for international travel. Check current Thailand entry requirements before departure — requirements may change based on global health conditions.

What to Watch Out For
Thailand presents more diverse health risks than typical beach destinations. Most are preventable with proper preparation and precautions.
Dengue Fever
Very common throughout Thailand, including Bangkok and tourist areas. Mosquitoes bite during daytime. Causes high fever, severe headache, and debilitating joint/muscle pain.
DEET 20%+ repellent, long sleeves, stay in screened/AC roomsTraveler's Diarrhea
Affects up to 50% of visitors. Higher risk when eating street food, which is one of Thailand's greatest attractions. Usually resolves in a few days but can ruin a trip.
Hepatitis A & Typhoid vaccines, careful food choices, DukoralZika Virus
Present in Thailand with ongoing transmission. Serious risk for pregnant women as it can cause birth defects. Spread by daytime-biting mosquitoes.
Avoid travel if pregnant; strict mosquito preventionChikungunya
Mosquito-borne virus causing fever and severe joint pain that can last months. Outbreaks occur regularly in Thailand, particularly during rainy season.
Mosquito bite prevention day and nightRabies
Thailand has one of the highest rabies rates in the world. Stray dogs and temple monkeys are common sources of bites and scratches. Fatal if untreated.
Pre-exposure vaccine, avoid contact with animalsJapanese Encephalitis
Mosquito-borne virus that can cause brain swelling. Risk is highest in rural/agricultural areas during monsoon season. Rare in cities but can be severe.
JE vaccine for rural/extended stays, mosquito preventionMalaria Risk in Thailand
Good news for most tourists: Bangkok, Phuket, Krabi, Koh Samui, Chiang Mai city, and major resort areas have NO malaria risk. However, rural and border areas do carry risk, particularly near Myanmar, Cambodia, and Laos borders.
Risk Areas
Risk areas: Rural forested areas along borders with Myanmar, Cambodia, and Laos. Higher risk in: Tak, Mae Hong Son, Kanchanaburi (rural), Trat (rural). NO RISK in: Bangkok, Phuket, Krabi, Koh Samui, Koh Phangan, Pattaya, Chiang Mai city, Chiang Rai city, major tourist islands.
Recommended Prevention
If visiting risk areas: Atovaquone-proguanil (Malarone) or Doxycycline are first-line options. Some border areas have drug-resistant malaria — we'll advise based on your specific itinerary. Note: Chloroquine and Mefloquine are NOT effective in Thai border regions.
Essential Health Tips
Street Food Safety
- Choose stalls with high turnover and fresh cooking
- Watch food being cooked to order (not pre-made)
- Avoid raw vegetables, unpeeled fruits, fresh juices with ice
- Opt for piping hot dishes — heat kills bacteria
- Carry hand sanitizer and use before eating
Bug Bite Prevention
- Use DEET 20%+ or Picaridin — dengue mosquitoes bite DURING THE DAY
- Reapply repellent after swimming or sweating
- Wear long, loose clothing in the evenings
- Sleep in air-conditioned or screened rooms
- Consider permethrin-treated clothing for jungle treks
Animal Safety
- Never touch or feed stray dogs, even if friendly
- Keep distance from temple monkeys (they bite!)
- Avoid elephants from non-ethical sanctuaries
- If bitten or scratched, wash wound immediately and seek medical care

Common Questions About Traveling to Thailand
Street food is a highlight of Thailand, but it does carry risk. Choose busy stalls where food is cooked fresh in front of you, avoid anything that's been sitting out, and skip raw items. The Hepatitis A and Typhoid vaccines are essential protection. Even with precautions, many travelers get mild stomach upset — it's often just adjusting to new cuisines rather than serious illness.
For most tourists staying in cities and beach resorts, no. JE vaccine is recommended if you're spending a month or more in Thailand, staying overnight in rural/agricultural areas, or visiting during monsoon season (May-October). If you're just doing Bangkok, Phuket, and Chiang Mai city for 2 weeks, it's usually not necessary.
Thailand has a very high population of stray dogs, and temple monkeys are notorious for biting tourists. Rabies is 100% fatal once symptoms appear, and getting proper post-exposure treatment in rural Thailand can be challenging. The pre-exposure vaccine gives you extra time to reach quality medical care if bitten.
No — Koh Phangan, Koh Samui, Phuket, and other tourist islands have no malaria risk. However, dengue is very common on these islands, so mosquito repellent is still essential. Save the antimalarials for trips to rural border areas near Myanmar, Cambodia, or Laos.
Temple visits are generally safe, but watch out for monkeys at popular sites like Lopburi Monkey Temple — they can be aggressive and bite. Remove shoes when entering (bring socks if floors are hot). Stay hydrated, as temple grounds can be hot with limited shade. Dress modestly with covered shoulders and knees.
Ideally 4-6 weeks before travel to allow full immunity to develop, especially for Japanese Encephalitis (requires 2 doses). However, don't skip your appointment if leaving sooner — Hepatitis A works within 2 weeks, and some protection is better than none. Rabies vaccine also requires multiple doses, so plan ahead if you need it.
