Immunizations The following vaccinations are recommended when visiting any area of Argentina:
- Hepatitis A
- Hepatitis B
- Typhoid
- Tetanus-diphtheria, polio and measles (as needed booster doses)
- If traveling to the north and northwestern areas of the country including Izuazu Falls, a Yellow Fever vaccination is recommended by the Centers for Disease Control (CDC).
- The CDC also recommends taking a prescription anti-malarial medication if traveling along the border areas of Bolivia and Paraguay.
- The Centers for Disease Control provides immunization information for travel in Latin America
This is what I found...but there are NO requirements for immunizations...these are just suggestions....it really depends on where you are traveling...how remote the area is...
You can go to the website of the CDC and look for more, but this is the basic list.
Yellow Fever shots if you go far North has been a must and last Spring there were issues with Dengue Fever in certain areas with mosquitoes. It was mainly in Paraguay if I remember right but there was a storm and many got blown into the northern region of Argentina and there were many that died and got very ill.
Hope this is of help...
