As some of you already know, my son and I are planning our maiden safari to the RSA in May 2013. I have talked to my doctor, my county health department, consulted the CDC website and the RSA website. I am certain that we do not need the YF vaccine if we are not travelling to or through countries with the disease on our way (countries listed on RSA's website). As scheduled, we are flying direct to Jo'burg from Atlanta on Delta. So, based on our scheduled travel. no YF vaccine required. My question, should we get the vaccine out of an abundance of caution? What if we have a non-scheduled stop someplace? Am I paranoid? Recommendations?
