Add a maximum volume for blood bags maybe, which has to be refilled with other people's blood (or extracted from the genetics grinder)
Or
Give Vampires really specific messages when using a blood bag.
"Dumb pubbie can't help but take a bite into the blood bag, what the heck?"
"Dr. Fred Frederick puts the needle into dumb pubbies arm, but something is not quite right"
Like a doctor who tries to use the blood bag on the vampire will instantly know that it's a vampire.
Risky because you're feeding a vampire, but also useful for proving vampire.
