American Samoa
Oceania · Updated May 2026
For most travellers to American Samoa, CDC recommends being up to date on routine vaccines plus hepatitis A, hepatitis B and typhoid. Depending on your itinerary and activities, MMR, rabies and COVID-19 may also be advised. There is no malaria risk, but dengue and Zika are present, so prevent mosquito bites. See a travel health clinic 4–6 weeks before departure.
No malaria risk; year-round mosquito-borne dengue and Zika risk.
Required for entry
No vaccines are currently required for entry to American Samoa from most countries.
Recommended for most travellers
CDC advises these for all visitors to American Samoa.
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.
Blood & Body FluidsHepatitis 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.
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.
Food & water safety
High riskTap water and ice are generally unsafe. Stick to sealed bottled water, boiled water, or water from a reliable filtration system. Avoid raw salads, unpeeled fruit, raw shellfish, and street food from vendors with poor hygiene. Wash hands thoroughly before eating.
