China Mieville had a book that deals with this. In the fantasy world he made the only thing that really gives the vampires power in a society with humans is the fear and myths around them. Outside of that the dependency on blood, inability to go out in the day, and the fact there had to be hard rules on creating new vampires because of the resulting power struggles made them really weak as a collective. iirc if the vampire population ever grew to the numbers it would need to create industry they wouldn't be able to feed enough to stay strong and sane, so uncontrolled vampire growth just leads to something like skid row.
