Place cranberries, sugar and vanilla in a medium saucepan. Place pan over medium heat and stir. Simmer cranberry mixture until all the berries burst, about 5 to 6 minutes.

Place orange peels in a large glass container with an airtight lid, or large mason jars with lids. Pour vodka over the orange peels.

Allow the cranberry mixture to cool. Pour the cooled mixture into the glass container(s). Cover tightly and set aside for 1 week. After 1 week, strain out the cranberries and orange peels and pour mixture into a clean bottle, using a funnel. Store vodka in the refrigerator.
