Travel smart to Vietnam with health and immunisation in mind

Why health planning matters for travel

Travelling to Vietnam can be a rewarding experience for holidays, work, study, or visiting family. A little advance health planning helps protect that experience by reducing avoidable disruption. Most travel health considerations relate to common infections, routine immunisation status, existing medical needs, and everyday safety rather than rare or extreme risks. A practical, evidence-based approach allows you to prepare calmly and travel with confidence.

Common illnesses travellers may encounter

In destinations with busy cities, regional travel, and warm seasonal climates, everyday infections circulate throughout the year. Respiratory illnesses and gastrointestinal infections account for most health issues seen in travellers. Exposure is increased by close contact in airports, buses, trains, markets, accommodation, and popular tourist areas, particularly during peak travel periods. Most illnesses are mild, but simple prevention remains worthwhile.

Immunisation and routine protection

Ensuring routine vaccinations are up to date is a key preventive step for most travellers. This commonly includes protection against measles, mumps, rubella, tetanus, diphtheria, pertussis, polio, influenza, and COVID-19. Depending on your itinerary, duration of stay, activities, and medical history, your GP may also discuss additional vaccines. Immunisation reduces the likelihood of illness and helps minimise disruption to travel plans. Recommendations are individual rather than one-size-fits-all.

Food, water, and everyday hygiene

Vietnam’s food culture is a highlight for many travellers, but changes in diet and unfamiliar foods can sometimes affect digestion. Regular hand hygiene, choosing food prepared and served safely, and paying attention to hydration support gastrointestinal comfort. Allowing time for regular meals and rest helps maintain energy during busy travel schedules.

Environment, insects, and heat

Heat and humidity can contribute to dehydration and fatigue, particularly during outdoor activities. In some regions, mosquito-borne illness risk makes bite prevention important. Using appropriate repellent, wearing suitable clothing, managing sun exposure, and pacing activities all support comfort and safety without limiting enjoyment.

Managing existing health conditions

If you live with a chronic medical condition, advance preparation is important. Carry enough medication for your entire trip, keep copies of prescriptions, and bring a brief medical summary if relevant. Long travel days, time-zone changes, heat, and altered routines can affect sleep, blood glucose control, pain levels, and fatigue. Planning ahead supports continuity of care and reduces stress if illness occurs overseas.

Healthcare access and travel insurance

Healthcare standards can vary between regions. Comprehensive travel insurance is strongly recommended and should include cover for medical treatment, hospital care, and emergency evacuation. Knowing where and when to seek care helps prevent minor problems from escalating.

When to speak with your GP before travel

A GP appointment before travel allows advice to be tailored to your health history, medications, immunisation status, and itinerary. This discussion focuses on practical preparation rather than restriction and supports informed, confident travel.
