Typhoid and Hepatitus A & B are the only vac's I would worry about personally. Hep is a disease that attacks the liver. A is transmitted by food and B by blood. It is highly infecteous.
A is supposed to be a big problem, I've read that 40% of locals are carriers, but in 15 years I've never known any one get it, Dengui is a problem but there is nothing to stop it, and again never known a tourist get it, but the locals go down with it all the time,
