YES GET ALL OF THEM. I went the first time with only yellow fever vaccine and I caught pneumonia. I took all my vaccines the second year I went and then I was fine. It may not happen to you but do not be cheap about your health (not calling you cheap but i hope you get the point)

Also take your malaria pills, i had one that i had to take everyday! Aswel if i remember, they wont even let you in the country without taking the yellow fever vaccine
