£250 approximately for the two jabs here in UK

Our government advises Dengue vaccinations for all of Thailand. But of course, they always will be on the safe side  Costs approx 5.200 THB 

Good point! I've heard that, but don't know if its true or not. SAG

I might just be repeating an overheard scare story here but isn't Dengue more of an issue in the area around Pattaya too?  Worth considering for most BMs maybe.

Its spreading quite fast. The course they use at MedConsult is QDenga which is 2 jabs with a 3 months interval. The cost is THB 1,999 per vaccination. BKK is still OK, but if you are planning on visiting your teerak in Isaan or Laos etc. its worth considering. SAG
