I can't seem to find any rules in the book regarding vampires and sunlight.

There aren't any. 

Urban fantasy is all over the map in regards to the strengths and weaknesses of vampires, werewolves, etc.  Rather than create a system for it all, Urban Shadows leaves it up to the player.

[quote]We’ve done our best to include in the moves and Archetypes everything we
think is necessary to make Urban Shadows work at your table. Part of our
design philosophy, however, is to leave holes all over the map for your group
to fill in. We want you to make the city come to life, to be the kind of vampire
or werewolf or wizard or faerie that you want to be, and to tell us what you
know about the world. We trust that your answers to those questions will be
far more interesting than anything we could set down as hard and fast truth.[/quote]
