Should i get vaccinations?

I understand that it's a financial burden, but rabies is nasty and dangerous and given the conditions in Haiti there's a chance you'll be exposed even if you're there for only 10 days. Bringing your own food and water won't reduce your risk of rabies exposure because most cases are related to bites/scratches from street dogs or small wild animals like a mongoose. If you're going to working in a remote area where you might not have access to good medical care, you might want to consider getting the vaccine because if you're exposed to rabies you'll need treatment right away or you could die. If you're working close to a major hospital, they may have a vaccine in the chance you're exposed so the necessity might be less. Good luck.
