Malaysia
Southeast Asia · Updated April 2026
Planning a trip to Malaysia? CDC recommends Hepatitis A and typhoid vaccines for most travellers because food and water hygiene varies once you leave large hotels. Your doctor may also discuss Hepatitis B, Japanese encephalitis, rabies, or chikungunya depending on whether you're heading to rural areas or Borneo. Book a travel health appointment 4–6 weeks before you go.
Malaria risk is limited to rural and forested areas. Kuala Lumpur, Penang, and George Town are not malaria zones.
Required for entry
No vaccines are currently required for entry to Malaysia from most countries.
Exception: Proof of Yellow Fever vaccination — If arriving from a country with risk of yellow fever transmission.
Recommended for most travellers
CDC advises these for all visitors to Malaysia.
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.
Food & WaterTyphoid
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.
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.
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.
Chikungunya
A mosquito-borne virus causing sudden fever and severe joint pain. Symptoms usually resolve in 7–10 days but can linger for months.
Malaria
Not a vaccineRisk in rural and forested areas, primarily Plasmodium knowlesi. No risk in Kuala Lumpur, Penang State, or George Town.
