As non-medical professionals, Justifi does not give specific medical advice and recommends that you follow the advice of a health care professional with regard to vaccinations. Therefore we suggest you go to your health care provider or local travel clinic to let them know you are going to Thailad and find out what vaccines they recommend for you, then make your own informed decision about what precautions you wish to take.
For general guidelines, we recommend you follow the CDC.gov advisories, which can be found here: http://wwwnc.cdc.gov/travel/destinations/traveler/none/thailand
