Good thinking Losligato, Bangkok or one of the other big cities in Thailand (Hat Yai, Chiang Mai) would be good places to get cheaper vaccinations. There are great hospitals in Thailand (I spent a couple of weeks in a Bangkok hospital with dengue fever, the specialist doctor in tropical illnesses was trained in the US, the hygiene and cleanliness was higher than anything I've seen in europe (all sterile syringe packages were opened before my eyes for example, just a detail which boosted my confidence) and my room was more like a good hotel room with cable tv and a waiter who came from the hospital restaurant to take my food orders. I think I had about 7 nurses running around checking my blood pressure and temperature all the time
