I travelled all over a few years ago and stopped in Africa for a bit. All the jabs are necessary and I recall having one of them in my backside? Anyway, you have to take malaria tablets cos theres millions of mozzies and you have to take them before, during and after you get back.
They didnt agree with me either but its a big risk if you dont take them and come back with malaria.
When I was there, I saw a woman with elephantitis. It was awful.
