Planning a trip to South East Asia? From the bustling markets of Bangkok to the tranquil beaches of Bali, this region offers unforgettable experiences. But before you pack your bags, it’s crucial to protect your health. Travel vaccinations are a vital part of preparing for your journey.
Whether you’re backpacking, honeymooning, or on a business trip, understanding the vaccines you may need helps ensure a safe and enjoyable adventure.
Why Travel Vaccines Are Important
South East Asia is a diverse region that spans several countries, each with its own health risks. The tropical climate, different hygiene standards, and exposure to new bacteria and viruses mean travellers are more likely to fall ill without proper protection.
Vaccines protect you from serious diseases not commonly found in the UK, such as Japanese encephalitis or typhoid. They also help prevent outbreaks and reduce strain on local healthcare systems.
Routine Vaccinations: Are You Up to Date?
Before you consider travel-specific jabs, check that your routine NHS vaccinations are up to date. This includes:
- MMR (Measles, Mumps, and Rubella)
- Diphtheria, Tetanus, and Polio (DTP)
- COVID-19 and flu vaccines, especially if you’re in a higher-risk group
These provide a foundation for health protection and may be required for travel insurance coverage too.
Recommended Travel Vaccinations for South East Asia
Vaccination requirements can vary depending on the countries you visit, the season, your activities, and your health condition. Below are the most commonly recommended travel vaccines for South East Asia:
1. Hepatitis A
- Risk: Contaminated food and water
- Common in: All South East Asian countries
- When to get it: At least 2 weeks before travel
Hepatitis A is a viral liver infection spread through consuming unsafe food or water. It’s one of the most common travel-related infections in the region, especially in rural areas.
2. Typhoid
- Risk: Contaminated food and water
- Common in: Indonesia, Vietnam, India, Nepal, Cambodia
- When to get it: Ideally 2–3 weeks before travel
Typhoid fever is a serious bacterial infection also spread through unsafe food and water. Backpackers and adventurous eaters are especially at risk.
3. Hepatitis B
- Risk: Blood and bodily fluids
- Common in: All South East Asian countries
- When to get it: Start at least 1 month before travel; accelerated schedules are also available
Hepatitis B can be contracted through unprotected sex, medical treatment, tattooing, or contact with infected blood. It’s essential for travellers planning extended stays or engaging in high-risk activities.
4. Japanese Encephalitis
- Risk: Mosquito bites in rural and agricultural areas
- Common in: Parts of Thailand, Vietnam, Laos, Cambodia, Indonesia
- When to get it: 6 weeks before departure for full protection
A potentially deadly virus affecting the brain, Japanese encephalitis is more common during the monsoon and post-monsoon periods. Risk increases for travellers spending extended time in rural areas.
5. Rabies
- Risk: Animal bites or scratches
- Common in: All South East Asian countries
- When to get it: 3 doses over a 3–4 week period; accelerated options available
Street dogs, monkeys, and even cats may carry rabies. Immediate treatment after a bite can be lifesaving, but the pre-exposure vaccine offers a layer of protection if help is delayed.
6. Cholera
- Risk: Contaminated water and poor sanitation
- Common in: Rural and flood-affected areas, parts of India and Bangladesh
- When to get it: At least 1 week before travel
Cholera vaccination is typically advised for aid workers, those visiting high-risk areas, or individuals with pre-existing health conditions. It’s given orally in two doses.
7. Malaria Prevention (Not a Vaccine, But Crucial)
While there is currently no vaccine for malaria available to most travellers, it remains a risk in parts of South East Asia. Preventive tablets and mosquito avoidance measures are essential in:
- Rural Myanmar, Laos, and Cambodia
- Eastern Indonesia
- Some parts of Vietnam and the Philippines
Book a consultation to check your route and receive advice on suitable antimalarial medication.

How Far in Advance Should You Get Travel Vaccines?
Some vaccines require multiple doses or take time to become effective. Ideally, book your travel health consultation 6–8 weeks before departure. This allows time for:
- Completing full vaccine schedules
- Developing sufficient immunity
- Starting antimalarial medication if needed
Last-minute traveller? Don’t worry. Some vaccines and fast-track schedules can still offer protection. Emcare Travel Clinic offers accelerated vaccination options to help.
Who Needs Extra Precaution?
Some travellers should take additional precautions, including:
- Backpackers: More exposure to street food, rural areas, and animals
- Children: More prone to insect bites, and often play with animals
- Pregnant women: Certain vaccines may not be safe during pregnancy—consult a travel health specialist
- Elderly travellers: Weaker immune systems may increase risk
- Travellers with chronic conditions: Especially those with liver or kidney problems
Other Health Preparations You Should Make
Travel health goes beyond vaccinations. While you’re getting protected, also consider:
- Anti-malarial tablets: For areas with mosquito-borne diseases
- Travel insurance: Ensure it covers medical care and evacuation
- Altitude sickness medication: If heading to highlands or mountain treks
- First aid kit: Include hand sanitisers, rehydration salts, and insect repellents
- Insect protection: Bring DEET-based sprays, nets, and long-sleeved clothing
