Of course, I could be completely off my rocker and recalling this incorrectly.
This is probably the biggest thing. My parents and I have been to many place in Brazil where the vaccine is recommended. Not once have we been asked by anybody to see our yellow cards for proof of vaccination, but it has been asked for in other countries since we had traveled to Brazil and they wanted to make sure we weren't carrying the disease.
