VACCINATION against Yellow fever is highly recommended and malariaprophylaxis is a must. I have used Lariam, but sometimes it gives you a feeling of depression, so the more expensive Malarone is better. Thats my own experience. Your local clinic or the pharmacy can advise you. Hepatitis is also recommended but not a must. Also my own experience.  FLIGHTS from:
