Hi there I'm needing some help as I don't know where to start. I want to travel to South and Central America my plan was just to land in Mexico and begin to walk about not literally but you know just travel around without any time scale go all the way down and back up the continent take as long as it takes and I was wondering what vaccines I will need and how do I go about getting them? I'm guessing a GP would be the first step but I just want to get the ball rolling. Any help/info wiould be greatly appreciated. I live in the UK thought you might need to know that.
