And who says that vampires aren't alive?

Vampires are alive...but then again...they aren't. Almost ALL body organs shut down and cease to work in vampires. They produce venom instead of blood...and I have no idea of how it circulates in their bodies since a vampire's heart no longer functions.

I guess the best way to answer this is that vampires ARE alive...but they're not alive in the same way that humans and other living creatures are alive. Whatever power animates a vampire is not the same thing that animates a human and other living creatures.
