From the neon-lit streets of Singapore to the mist-covered mountains of Vietnam, South East Asia is a dream destination for many.
However, because the region spans diverse climates – from ultra-modern cities to tropical jungles – the health risks vary significantly between borders.
If you are planning a multi-stop adventure in 2026, McMinns Pharmacy is here to help you navigate the requirements for many countries in South East Asia.
Thailand: The Backpacking Hub
Most travellers to Thailand need the “essentials”: Hepatitis A and Typhoid, as these are common in areas where food and water hygiene may vary.
- Special Consideration: If you are trekking in northern rural areas or visiting animal sanctuaries, a Rabies course is highly recommended. Thailand has a high population of stray dogs, and pre-exposure vaccination simplifies treatment if you are bitten.
Singapore: The Urban Exception
Singapore is one of the cleanest cities in the world, and the risk of food-borne illness is low.
Most travellers only need to ensure their routine UK boosters (Tetanus, Diphtheria, and Polio) are up to date.
- Mandatory Entry: Singapore strictly enforces Yellow Fever certificate requirements if you are arriving from a high-risk country (such as parts of Africa or South America).
Indonesia: Island Hopping Safety
With over 17,000 islands, Indonesia’s health profile is varied.
- Japanese Encephalitis (JE): This mosquito-borne virus is a risk in rural parts of Bali and Java, especially near rice paddies and pig farms. If you are staying for more than a month or visiting rural areas, the JE vaccine is a wise investment.
- Malaria: While major tourist hubs are low-risk, remote islands like Flores or West Papua may require antimalarial tablets.
Malaysia: Peninsula and Borneo
Malaysia is generally safe, but those heading to Borneo for wildlife tours face different risks than those staying in Kuala Lumpur.
- Hepatitis B: Recommended for long-stay travellers or those who might seek medical/dental treatment or tattoos, as the virus is more prevalent here than in the UK.
Vietnam: Culinary Adventures
Vietnam is famous for its street food, which makes Typhoid and Hepatitis A vaccinations essential.
- Dengue Fever: There is no vaccine currently on the standard UK travel schedule for short-term tourists, and Dengue is common in Vietnam. We recommend high-strength DEET repellents, which we stock at our Wishaw clinic, to prevent mosquito bites.

To ensure you are fully protected before you fly, we recommend booking your appointment at McMinns Pharmacy at least 6 to 8 weeks in advance.
