Although only Miss Universe for a day so far, Vega is already taking her role seriously. "When we participate in a pageant we are examples to young and teenage girls," she tells PEOPLE. "It's very delicate."
"I want to demonstrate that it is not the most important thing to be beautiful and have a glamorous life. It's about feeling beautiful. Become an intelligent, professional, hardworking woman with a great heart. That is the example I want to set," she says.
