My husband and I (ages 68 and 70) have signed up for Jan 29, 2020 Patagonia tour which includes Chile and Argentina. At the end of that tour we will spend more time in Argentina (San Carlos de Boriloche and Iguazu Falls) and then on to Brazil (Brazilian side of Iguazu Falls and Rio). We will do this part on our own.
My doctor recommended typhoid, malaria, hepatitus A, yellow fever, and tetanus shots.
That's a lot of vaccines! I am just curious if others are getting this "shot up" and is it really necessary based on traveling to major tourist destinations. Thank you.
