Create Vampires/Scientific Evidence

Science:
What is Science? Science by definition is "the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment." This complex definition is "Powered by Oxford Dictionaries." Where in the world of science and technology, does vampirism fit? From the Wikijournal of Medicine, we learn that "Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness." 

Science, Vampaiyerism, and Vampirism
Is There Any Factual Evidence for The Existence of Vampires? Vampaiyerism is closely associated with vampirism, meaning activities and events closely linked with vampire of folklore, many fictitious vampire creations told about in stories, were characters reflecting actual people who were often drugged, maybe involved with drugs, often reported as dead, may be found buried, maybe associated with fraud, drug abuse, witchcraft, and even "dark magic." Vampaiyerism and vampirism is seldom associated with Science, yet at times, Science and vampaiyerism, and by close association, vampirism, is connected in public broadcasts, and in the news. From Wikipedia: In modern times, the vampire is generally held to be a fictitious entity, although belief in similar vampiric creatures such as the chupacabra still persists in some cultures. Early folk belief in vampires has sometimes been ascribed to the ignorance of the body's process of decomposition after death and how people in pre-industrial societies tried to rationalize this, creating the figure of the vampire to explain the mysteries of death. Porphyria was linked with legends of vampirism in 1985 and received much media exposure, but has since been largely discredited.
