Are you planning a trip to South East Asia and unsure which vaccinations you may need before departure?

Recommended vaccinations for South East Asia commonly include routine immunisations, hepatitis A and B, and typhoid. Depending on your itinerary, duration of stay, and potential exposure risks, additional vaccines such as Japanese encephalitis, rabies, cholera, or yellow fever may be appropriate.

Disease risk varies between countries including Thailand, Indonesia, Vietnam, Malaysia, Cambodia, and the Philippines, particularly between urban and rural settings. Entry requirements may also apply if arriving from a country with yellow fever transmission.

Routine vaccinations should be up to date before travelling to South East Asia, as outbreaks of common infectious diseases continue to occur in parts of the region.

Even when these vaccines were completed under Singapore's National Childhood Immunisation Schedule, immunity can decrease over time and booster doses may be required.

Common routine vaccines to review include:

• Measles, Mumps and Rubella (MMR) – A booster may be required if previous doses are incomplete or immunity is uncertain.
• Diphtheria, Tetanus and Pertussis (Tdap) – A tetanus-containing booster is generally recommended every 10 years.
• Polio – A single adult booster may be advised for travel to certain regions if childhood vaccination was completed.
• Influenza (Flu) – Annual vaccination is recommended, particularly before peak influenza seasons, which may occur year round in tropical regions such as South East Asia.
• COVID-19 – Booster recommendations depend on age, risk profile, and prevailing public health guidance.

Travel vaccinations for South East Asia are recommended based on the diseases that are endemic in the region and your individual travel plans. Not every traveller requires every vaccine, so a pre-travel assessment is important.

Vaccine	What It Protects Against and When It Is Considered
Cholera	Protects against cholera, a bacterial infection causing severe diarrhoea. Considered mainly for higher-risk travel such as humanitarian work or visits to areas experiencing active outbreaks in parts of South East Asia. Some oral cholera vaccines may also provide limited protection against certain strains of enterotoxigenic Escherichia coli (ETEC), a common cause of traveller's diarrhoea.
Hepatitis A	Protects against hepatitis A, a viral liver infection spread through contaminated food and water. Risk remains present in parts of South East Asia, including urban areas where food handling may pose exposure.
Hepatitis B	Protects against hepatitis B, a viral infection transmitted through blood and bodily fluids. Considered for longer stays, potential medical procedures, tattoos, or close personal contact.
Japanese Encephalitis	Protects against a mosquito-borne viral infection more common in rural and agricultural regions. Considered for extended stays, outdoor activities, or farming exposure.
Rabies	Protects against rabies, a viral infection transmitted through animal bites or scratches. Considered where animal exposure is possible, including stray dogs or wildlife. Pre-exposure vaccination reduces the number of injections required after a bite, but urgent medical treatment is still necessary if exposure occurs.
Typhoid	Protects against typhoid fever, a bacterial infection spread through contaminated food and water. Relevant for travel to smaller cities, rural areas, or when eating in settings with variable sanitation standards.

Mosquito-borne diseases such as dengue, chikungunya, Zika, and malaria are present in parts of South East Asia, although risk varies by country and location. Dengue is widespread across the region, including urban areas, while malaria is typically confined to certain rural, forested, or border regions in selected countries.

Vaccines are limited or not routinely recommended for most mosquito-borne diseases affecting travellers. In areas where malaria risk is present, preventive medication, known as malaria prophylaxis, may be recommended depending on the specific destination and travel itinerary.

If you are unsure which vaccinations are suitable for you, our doctors can advise based on your travel itinerary, duration of stay, medical history, and current immunisation status.

Travel health involves more than vaccinations, as food hygiene, mosquito prevention, and general precautions also reduce illness risk. Traveller's diarrhoea, mosquito-borne infections, and heat-related conditions are common concerns in the region.

You may also wish to consider:

• Eating thoroughly cooked food and avoiding untreated water
• Practising regular hand hygiene
• Using insect repellent and protective clothing
• Staying well hydrated in hot and humid climates
• Bringing necessary personal medications
• Ensuring adequate travel medical insurance

If fever, persistent diarrhoea, rash, or respiratory symptoms develop during travel or after returning to Singapore, consult a doctor and mention your recent travel history.

Your vaccination will also be updated to the National Immunisation Registry (NIR) where relevant, this allows you to keep a record of your vaccinations.

Vaccinations offer significant individual benefits by boosting the immune system's ability to fight off specific infectious diseases. They reduce the risk of contracting serious illnesses, leading to fewer medical visits and a lower chance of hospitalization.

By staying up-to-date with vaccinations, individuals can also enjoy a greater sense of well-being and freedom to engage in various social activities, knowing they are protected against contagious diseases.
