The recommendations are, Typhoid ($125) Hepatitis ($120) and Malaria (price would depend on your insurance/pharmacy). check with your doctor, the only mandatory is Malaria.
The suggestion is to schedule a consult with their travel doctor ($80.00) which would include the prescription for Malaria pills. I would suggest checking with your own Physician first.
Yellow Fever: Recommended to take 4-6 weeks prior to travel If you already have a certificate, that has expired, it is NOT necessary to get another shot, they can re-certify you. and issue another certificate. If you do not have one, the yellow fever vaccine is not readily available...begin checking with health clinics to compare prices, last year Dekalb medical center was the least expensive, some travelers were able to bill their insurance..
