The Yellow Fever vaccination recommendations for Africa have been revised by the World Health Organisation (WHO).  Following this revision, the South African Department of Health has issued a statement regarding the requirements for travel between South Africa and Zambia.
All passengers travelling from Zambia to South Africa, and vice versa, will now require proof of Yellow Fever vaccination.  This was not a requirement before.
Please advise all your clients travelling to Zambia of this requirement.  In-transit passengers will also require proof of vaccination.
