We have done some hardcore research on what immunizations we should get beforehand in order to keep a sane piece of mind in some of the countries we are traveling to.  Our list is:

1. yellow fever (need this to get into some S. American countries)

2. typhoid

3. hepatitis A

4. polio (although we were all immunized as a baby, we had to get the adult booster)

5. flu shot

After meeting with a “travel nurse” she convinced us kindly not to get the Japanese encephalitis shot ( a two part series, over $500), we were very thankful to not have to get that.  We also had to meet with the travel nurse to give us some intense stomach (diarrhea) medicine and malaria pills.
