Paying homage to Wes Craven who recently passed away, I have a question about one of my favorite vampire movies that Craven was an Executive Producer, Dracula 2000.

In the movie, Van Helsing is the "keeper" of Dracula. Van Helsing must be able to survive in order to keep Dracula entombed for long periods of time. He puts leeches on Dracula's body and then injects Dracula blood into his own through the leeches. This process keeps Van Helsing immortal, but only for a time, because he has to continually repeat the process.

How did Van Helsing not turn into a vampire after this process?
