Lappy, I don't believe that any of those countries require any vacinations but if one is required, you will be notified. As for any banned substances, that too will be told to you. However, you will have to go through customes when you re-enter the US and if you have something that needs to be declared, you'll have to do so. Again, you will be told what has to be declared such as too many bottles of booze etc. You are allowed a certain amount of goods from those countries duty free so unless you go overboard, you won't have to declare anything. Some people try to sneak past customes things that should have been declared but if they are caught, it could be costly. I wouldn't worry about too much of that but if you have any questions, just carefully read the customes declaration.
Also, be aware of what you take into those countries. It's much harder to hide things since 9/11 and when you are in a foreign country, you don't want to mess with their inspectors. Be prepared to have all your luggage inspected, inside and out.
