I'm fairly confident Vampires in this universe aren't undead like Zombies otherwise Zombina's formaldehyde based blood would not have had adverse effects on her since formaldehyde is poisonous to the living.

There are already several extra-species that are confirmed to drink blood but are not undead such as Leeches, Mosquitoes and Lamprey.

Plus Curie's own Secrets pages suggests exactly what the first anon said. It's possible that the vampire virus is more like a fantasy version of rabies which bats are known to carry.
