Hepatitis A, Typhoid, Polio and Tetanus-Diphtheria vaccinations are currently recommended and Thailand is deemed to have a risk of Malaria (with the exception of Bangkok) and the Zika virus. If you’re entering Thailand from a Yellow Fever zone, possession of a valid Yellow Fever inoculation certificate is required. For any current travel health advice, you should seek guidance from your GP at least four to six weeks prior to travel.
