Yellow Fever immunization is the only jab that is mandatory for entry into Tanzania, but you should also look at getting a tetanus booster and a typhoid vaccination, plus anything else your local healthcare professional or travel clinic recommends. It is recommended you consult with a specialized travel clinic regarding what vaccinations are suggested for travel to Tanzania over and above the mandatory Yellow Fever inoculation. And it is advisable to begin vaccinations approximately six weeks prior to your arrival so that you’ll have adequate time to get them all in.
