Make sure you have the Immunizations tech write the yellow fever shot down in a World Health Organization "International Certificate of Vaccination" PHS-731 (yellow, passport-size shot record).
I was ahead of the game and went right in to base medical to get the shot and a printout of the records only to later receive the Indoc email which required that it be written down in the yellow booklet.
Easy fix, but one trip would have been better than two.
