I'd go with the WIMF-Rule (what is more fun). Vampires being merely humans infected by a virus with some dietary requirement and magic powers is, IMHO, not as fun as vampires being animated corpses, undead beings who die at dawn and rise at dusk. Vampires being sentient viruses that inhabit corpses and believe to be simply infected humans is closer to the later.
In actual play, this could be handled by "don't ask, don't tell" - you could play entire campaigns, struggling with the nature of your character ic, without your GM ever deciding what exactly your character was, infected human or undead monster, the line is that blurry between the two views in game.
Actually, I'm honestly persuaded that infected humans fits better with the way science and magic work by themselves and together in SR, and it builds on the solid foundation metagenes and goblinization have built for similar person-changing effects. But I'm willing to work even with the "animated corpses raised by magic" (even if I've to state that even when this kind of explanation is used, undead are assumed to slip into a death-like sleep during day, die and resurrect every day is just too goofy), a la Crow, as long as it is understood that it is the original person's consciousness, mind, soul, spirit, ba, ka, call it as you like, that animates and self-directs the corpse.
It most emphatically must not be a shambling mass of virus, a possessing spirit, or whatever, that consciously dupes the world in mimicking the dead human, it's stupid, goofy, and totally destroys any interest such a character concept may have either as PC or NPC. Master shedim are already available as an explicit option to cover that angle.
I honestly think the sentient virus idea is too farfetched, where the virus is supposed to record and carry the massive amount of information it requires to have a consciousness, a virus is a material object, not a spirit, so it's subject to scientific constraints, and I do not believe the self-delusion angle is workable (besides the loathsome fact it obliges you to play a self-deluding pathetic loon, I do not want my Infected PCs or NPCs to be reverse DeVrieses, thank you), since as I said before, it's a self-contradiction, you are your memories and personality, so if there is a corpse magically-animated that has your memories and personality, and thinks it's you, then to all kinds and purposes, it's you, the conditions of the body matter not at all, and the existence of the soul/spirit matter not, except insofar it means there are two copies of the same individual, one talking and walking the earth as a vampire/wendigo, the other in some afterlife Metaplane doing soul business, much like two clones that have the same memories. They may eventually diverge into separate individuals from different experience, but practically it matters not, since the afterlife in SR, if it indeed exists, is cut off from from any proven and reliable contact, so to all purposes the only version of the individual that matters for play is the one walking the Earth.
