Argentina
South America · Updated April 2026
Planning a trip to Argentina? CDC recommends Hepatitis A and typhoid vaccines for most travellers because food- and water-borne illness is the main concern outside major hotels. Your doctor may also discuss Hepatitis B, rabies, or yellow fever — yellow fever is recommended for travel to Iguazú Falls and the northeast. Book a travel health appointment 4–6 weeks before departure.
Argentina has no general malaria risk. Yellow fever is a concern in Corrientes and Misiones provinces, including Iguazú Falls.
Required for entry
No vaccines are currently required for entry to Argentina from most countries.
Recommended for most travellers
CDC advises these for all visitors to Argentina.
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.
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.
Yellow Fever
A serious mosquito-borne virus found in parts of Africa and South America. Proof of vaccination is required for entry to many countries if arriving from a risk area.
