The Vampyre*, a short gothic novel by John William Polidori, was first published in 1819 and is considered the first modern vampire story. The story features Lord Ruthven, a seductive aristocrat with unnatural powers over men and women, and an insatiable thirst for blood. Polidori's innovative portrayal of the vampire as a Byronic figure is said to have set the template for the modern vampire.
Just to pick a nit...
Stoker's story was inspired by "The Vampyre" by physician John Polidori, who doubtless knew whatever his contemporary medics knew about blood.
Polidori, Lord Byron, and Mary Shelley told scary stories to each other by Lake Geneva in 1816, the "year without a summer". It couldn't get more gothic.
