I and a friend are leaving Apr 30 for a 10 day hunt in Limpopo, South Africa. When looking into required immunizations, I noticed on the CDC web site that South Africa requires proof of Yellow Fever Immunization if coming from a YF area of transitioning through such an area. My flight is Dullus to JoBerg with a stop over in Dakar (a YF region). According to my itinerary, we do not de-plane in Dakar. Does anyone know if I need a YF vacination prior to arriving in South Africa?
