Imagine the countdown to a thrilling Halloween night, where the veil between worlds thins, and vampires, those mythical creatures, stir in their coffins. Among the many lore surrounding these blood-sucking beings, one intriguing aspect is their blood type. But unlike humans, vampire blood types aren't determined by A, B, O, or AB. Instead, they're categorized based on the types of blood they prefer to consume.
In the vast world of vampire literature and mythology, the most common classification is sun-sensitivity versus moon-type. The sun-sensitive vampires (who combust in daylight) are often more powerful, while moon-types (who are active during night) are usually less dangerous. But what about their dietary preferences? Let's dive into the "blood type" categorization of these mythical creatures.
Human Blood Types
In the human world, blood types are crucial for transfusions and compatibility. But vampires, immune to diseases and infections, don't need compatibility. Instead, they hunt for taste and power.
A human's blood type, however, can influence a vampire's abilities and strength. For instance, Type O is often believed to provide the most energy, while Type AB is argued to grant a unique ability boost.
Sun-Sensitive Vampires
Sun-sensitive vampires, often portrayed as traditional, old-world vampires, prefer human blood. They're drawn to the iron, proteins, and other nutrients it provides. The power derived from human blood enables them to withstand sunlight, albeit with great difficulty.
Subsets among sun-sensitives favor specific human blood types. For example, some may prefer Type O for its high iron content, while others might lean towards Type AB for its rare combination, believing it offers greater power.
Moon-Type Vampires
Moon-types, more adapted to modern human society, often feed on animals. Their preference for animal blood is attributed to the reduced risk of detection and the minimal sun-energy boost from human blood. They typically feed on common domestic animals like cats, dogs, or cattle, not discriminating between blood types.
However, some moon-types may have unique preferences. For instance, those living near sanctuaries or reserves might favor exotic animal blood, like that of deer or wolves, for its supposed strength orroviding a different 'taste'.

InClinical settings, blood types are divided into ABO and Rh factors. This classification may also apply to some vampire mythologies.
Angela Slatter's "Vampires through the Centuries" series explores this concept. Vampires in her tales are ABO-type sensitive. They prefer matching blood types, thus weakening those who don't match.
ABO Compatibility
In Slatter's universe, vampires with Type O blood can consume any human blood type. Type A vampires can drink from Types A and AB, Type B from B and AB, and Type AB can consume all.
This compatibility follows the basic human rule - but with an intense, powerful reaction. A compatible drink provides peak strength, while an incompatible feed leaves the vampire weakened.
Rh Factor
The Rh factor, which determines whether a person has Rh-positive or Rh-negative blood, is another level of complexity. In this mythology, Rh-negative vampires are usually more powerful, able to resist sunlight longer.
However, they must be cautious. Drinking from an Rh-positive human can cause painful, even fatal, reactions. Conversely, Rh-positive vampires are weaker but better tolerated by Rh-positive humans.
While fascinating, these categorizations remain in the realm of fantasy. Real-world vampire hunters need only concern themselves with human blood types. But for lovers of vampire lore, exploring these 'blood types' adds depth to our understanding - and fear - of these mythical creatures.
