Shots needed to enter US after cntrl/sth america?

Anyone know what vaccinations are required to enter the US after central/South America?

Going to Mexico in two days could I get the necessary shots there?

I'm in Portugal atm and getting shots in a foreign country proved to be a giant pain in the ass.When I finally got to the moment of injections they pull out 2 needles when I thought I was getting 4.One is definitely typhoid the other one looks like it says malaria when I asked for yellow fever.

I know when I eventually go home I need a yellow fever vaccination or I think il get put in quarantine. Phone Post 3.0

You won't need anything. I was in Brazil, Costa Rica, Nicaragua, Colombia, Ecuador, and Peru. Came home and wasn't even asked about it. Phone Post 3.0

There are some wonderful travel agents that can pack you into the back of a van for a really good deal. 

 

They hate driving back empty.
