Love at First Bite (1979)

Dracula and Renefield relocate to '70s era New York in search of Cindy Sondheim, the reincarnation of Dracula's one true love, Mina Harker. "Trouble adjusting" is a wild understatement for the Count as he battles Cindy's psychiatrist, Jeffrey Rosenberg, a descendant of Van Helsing, who may almost certainly, possibly, may be in love with Cindy too.
