So, I had shots for a bunch of horrid diseases.
I was surprised to learn I don't need Malaria tablets. Apparently most parts of Asia that I am visiting are Malaria free. The nurse actually pulled up this site for each destination I was visiting to confirm it was OK to go without. Here's the page for Cambodia for example
I foolishly asked the nurse, "So why don't the people who live in Malaria areas take tablets for Malaria then? Don't they get Malaria?"
"THEY DO, and THEY DIE" she said!
