One can draw many parallels between the jew and the image of the vampire: both are parasitic and drain the life force out of the host –in the case of the vampire the victim and in the case of the Jews an unwitting nation. Both have a symbolic connection to blood, and contact with either of them taints the blood.
The people we today call “Jews” are literally the descendants of Satan.
Dracula’s role as racial outsider results from Stoker giving him Jewish attributes and largely basing him on depictions of the Wandering Jew.
Stoker was very interested in the legend of the Wandering Jew, whose attributes are echoed in Dracula.
Dracula’s evil and supernatural nature and his blasphemy of Christianity ultimately cast him in the role of Antichrist.
