We don't have enough to say that it is a trait only for the Banshee. We saw in Season 4 that a supernatural can't be two things - nogitsune couldn't be fox and wolf - that is also a logical explanation for Lydia's "immunity" since she could reject the bite simply because you can't turn a banshee (or anything else) into a different creature.
