Probably because gringos don't routinely get yellow fever immunizations and Ticos do.
It's actually very difficult to get a US doctor or agency to vaccinate for yellow fever.
The Colombiana that I know is a naturalized Tica and she has never had a yellow fever vaccination, yet travels back and forth somewhat frequently. She told me she has never been asked about it and was surprised when I told her I needed to make sure I had my card with my passport when we left Colombia. I was asked to provide my vaccination card though which I had put in my back pocket just to see if they would ask about it.
I live in a smaller sized city and was able to get my yellow fever shot at a local clinic with no problem. I did call ahead though to make sure they had it and I was told they usually keep 10 shots on hand. It did cost me $98.00 for the vaccination though. I also did the Hep A & B along with TDAP as well which were all covered under my insurance at the time. The Hep A&B was a 2 visit injection and my insurance was billed 210.00 for those and 15.00 for the TDAP.
