i travelled to ghana recently for a buisness trip, as i got to kokota international airpot, i was asked to provide a yellow vaccination card, which i thought was not needed , i later had to pay 20ghana cedis( 2 thansand naira) at the airport to get the card, though it looks better than nigerians yellow card, my problem now is , i want to apply for south africa visa, someone should please advice me if i can go ahead and use the yellow card that was issued to me at ghana airport , i dont want to be denied for that reason. thanks.
