Pat, nothing to do about being blonde, certainly! This was a question that Neviboy posted when he was going there a long time ago, and didn't want to get the shot! It seems to be a very murky area, especially since you had to fax copies of those shots ust last February! I guess, really, I am trying to find out if I need those shots if I am coming into Rio, and leaving from the same port the next day!
