How do you turn into a vampire without being bitten?

Answer 1

in fantasy novels, a vampire spawn does not always need to be bitten. sometimes, the vampiric virus is within the vampire's saliva and thus, anyone the vampire bites, whether they just drink from them or kill them with a bite, the victim will rise as a vampire spawn. in other cases, the vampire gives the victim some of their blood to drink and after ingesting it, they will carry the vampiric virus.

this is true in the real world application. a vampire's bite is just as septic as any other human mouth, so the method of biting to turn someone doesn't work and can give someone a very nasty infection at the bite area. if a real world vampire wants to give someone else the vampiric affliction, they donate blood which the victim ingests.

the real world application of the vampiric affliction is a disease of the blood, so it can be given to others thru blood transfer. the normal precautions of blood donation (disease screening, either curable or constant) also play an important factor, similar to donating blood to a hospital. not much vampire blood is needed to turn another person; sometimes it takes more than a mL, sometimes not. it depends on how well the victim's body handles the first dose of blood. at most, a coffee cup of the vampire's blood would assure anyone that drinks it would carry the virus.

Answer 2

There is no known way to turn into a vampire without being bitten, as the traditional lore and mythology surrounding vampires typically involve being bitten by one to become a vampire.
