Carmilla, the Lesbian Vampire (2004)

Based on the novel CARMILLA by Sheridan Le Fanu, VAMPIRES VS. ZOMBIES pits two of horrordom's most feared creatures against one another. When young Jenna becomes affected by a mysterious vampiric disease, she begins to hallucinate, and her father whisks her away on a journey to find the source of the infection. On their way to the hometown of Baroness Vampire Carmilla, suspected to be the cause of the problem, the two encounter a friendly General, school-girl zombies, cannibals, and of course, the power-mad, evil Carmilla.
