[general] Can a vampire drink from a priest/holy man?
gpt
Yes.  The blood of such a person isn't sanctified in the same way that holy water is, so it is not harmful to the vampire in that way.  
Of course, such a person probably has several holy symbols around, so they might be hard for the vampire to actually get to, but once it did, it could feed safely.
