All great advice. I would add the Typhoid fever vaccination, and stress including the Hepatitis A&B vaccine series' (as opposed to Gammaglobulin). Give yourself a goodly 3 month lead time, as the HepB series takes this long for 3 shots.

Perhaps include the rabies series as well-depending on the style of touring you will be doing (?incuding trekking/camping). Remember it's not just dogs that may carry rabies-travelling through a bat infested area as an example. This series is not full protection, but gives you extra time to get to a clinic/doctor, and also reduces the number of post exposure shots required.

My HMO gave me vaccines for only 1 co-pay (?20$)s, but I allready had the Hep B series+booster(s). Oddly I'm still not a responder (ie no measureable titer).
