The vaccines you need for Thailand depend on where you go, how long you stay and what you’ll be doing. Several vaccines are recommended for your health. We’ll confirm current entry requirements at your consultation.
A beach holiday in Phuket or Koh Samui is different from trekking near the northern borders or backpacking for months. Dengue occurs across the country, so use insect repellent day and night. Rabies is present, so avoid touching dogs and monkeys, including at temples. Heat, strong sun and busy roads, especially on a hired scooter, also need care.
TMB clinician insight
ββThailand is still the trip our Irish patients ask about most, whether it’s Bangkok, Phuket or the islands around Krabi. One thing I always raise is tattoos and piercings. If you’re tempted on holiday, make sure the needles and equipment are sterile, because hepatitis B and other blood-borne infections can be passed on.βΒ
