Exposure Therapy is a psychological treatment for anxiety disorders and isn't the same as deliberate exposure to pathogens in order to trigger an immune response, like you're talking about with children. And *that* sort of exposure does work with adults to some extent (like in vaccines), but it happens more in childhood because that's when everything is new to the immunue system.
