Split each vanilla bean in half lengthwise and place them into a bottle. Pour in the vodka so that it completely covers the vanilla. Close the bottle and keep it in a cool, dark place (not the refrigerator). Shake the bottle periodically. Let stand for at least 3 weeks, however, the extract will reach full flavor after a few months and will be perfect for use. You can store it in your pantry for years.
