One of my main concerns with traveling to South America with Jack  was keeping him healthy on our trip. I am an admitted germaphobe, so I seriously would have put that kid in a plastic bubble if it was socially acceptable. It was difficult to decide with our Pediatrician which vaccinations were imperative for travel and which we could forgo.
The University of Louisville has a travel clinic that offers medical advice and treatment for international travelers. Based on your travel itinerary, one of their physicians will give recommended vaccines and also prescribe prophylactic medications just in case of illness (because who really wants travelers' diarrhea on a vacation?). They can help your family prevent everything from altitude sickness to Malaria, and offer their services to both adults and children.
They do charge for their treatment, and don't accept health insurance...so it can be a little expensive for some. But, can you really put a price on not getting Hepatitis A?
If you'd like more information on the U of L Travel Clinic, go their website . Or call and make an appointment at (502) 852-3691.
