The typhoid vaccine is not required for international travel. The typhoid vaccine should be used only by people traveling to high-risk areas who will be:
- Staying for more than six weeks
- Staying in rural areas or small towns
- Choosing to eat uncooked foods and unpeeled fruits, and drink unbottled water
There are two forms of the typhoid vaccine that are available in the United States; each one is most effective when given at a particular age. Although the vaccines are both fairly effective in preventing typhoid (ranging from 50-80 percent), you should still heed the warning "boil it, peel it or forget it."
