Like Peter mentioned, you'll need blood to turn the new vamps into humans so they can be killed.
So you don't have to run to the Hyperion, there are now tranquilizer darts in a med box in the mini-fridge in the weapons room. They have the blood in them. It doesn't really matter where you hit the vampires, but the left side of the chest, over the heart, will be the quickest.
Let me know when the box is half-empty and I'll make more.
