Vietnam
Southeast Asia · Updated April 2026
Planning a trip to Vietnam? CDC recommends Hepatitis A, Hepatitis B, and typhoid vaccines for most travellers because food and water hygiene varies once you leave your hotel. Japanese encephalitis and rabies are worth discussing with your doctor if you're heading to rural areas or staying a long time. See a travel doctor 4–6 weeks before departure to tailor the plan to your trip.
Malaria risk is limited to rural areas — Hanoi, Ho Chi Minh City, Da Nang, and Nha Trang are not malaria zones. Dengue is a year-round mosquito-bite risk across much of the country, even where a vaccine isn't advised.
Required for entry
No vaccines are currently required for entry to Vietnam from most countries.
Recommended for most travellers
CDC advises these for all visitors to Vietnam.
Hepatitis A
A contagious liver infection spread through contaminated food and water. Most travellers to regions with less reliable sanitation should get this vaccine.
Two doses at 0 and 6–12 months. Over 90% of people develop protective antibodies within a month of the first dose, so one dose is usually enough for the trip itself. No booster needed after the full series.
Hepatitis B
A liver infection spread through blood, sexual contact, and contaminated medical or cosmetic equipment. Recommended for most travellers, especially those with longer stays or possible medical exposure.
The full series is three doses over 6 months. An accelerated 4-dose schedule (0, 7, 21 days, 12 months) is available when combined with Hepatitis A. Partial protection starts after the first dose.
Typhoid
A bacterial infection spread through food and water contaminated with the faeces of an infected person. Risk is higher in rural areas and when eating with locals.
The injected vaccine is a single dose at least 2 weeks before travel and lasts 2 years. The oral version is four capsules taken every other day, completed at least a week before travel, and lasts 5 years. Neither is 100% effective — safe food and water habits still matter.
Recommended for some travellers
Depends on your itinerary, activities, duration, or health.
Japanese Encephalitis
A mosquito-borne virus affecting the brain, found in rural parts of Asia. Risk is highest during rice-paddy season in rural areas.
Rabies
A fatal viral disease spread through the bite or scratch of an infected animal — most often dogs, bats, or monkeys. Pre-travel vaccination simplifies treatment after exposure.
Malaria
Not a vaccineRural areas only, with rare cases in the Mekong and Red River deltas. No malaria risk in Hanoi, Ho Chi Minh City, Da Nang, Hai Phong, Nha Trang, or Quy Nhon. Most tourist itineraries do not need malaria pills.
Routine vaccines to be up to date on
CDC advises every international traveller to have these current.
Measles-Mumps-Rubella (MMR)
Diphtheria-Tetanus-Pertussis
Polio
Flu (Influenza)
Chickenpox (Varicella)
Shingles
COVID-19
Entry requirements
For US citizens. Non-US travellers should check their government's guidance.
Dengue is a year-round risk across much of Vietnam, with larger outbreaks every 2–5 years. Mosquito-bite prevention matters even when a vaccine isn't advised. CDC does not currently advise the chikungunya vaccine for travel to Vietnam.
