I am taking KLM from New York to JRO this summer roundtrip for a week to do a safari. I heard it is required to have a yellow fever shot. I also have heard it is NOT required if you are on the KLM flight from Amsterdam. I am not sure if this is dated information or if it is true that you do not need the shot. Or should I get the shot anyway bc it truly is a risk? Never been to Africa so Not sure. Thanks'
