Well, I'm French, although I now live in NI. When I went to SA, I had Hepatitis injections done, not sure which ones, and it was only as a precaution.....But for Malaria, all you can do is buy tablets, and protect yourself from bites as much as possible. Apart from that, nothing really! Never had a problem in SA (apart from getting robbed twice, and sunburn, obviously!lol)
