What effect would vampire venom have on a half human half vampire hybrid?

I don't think that venom can affect a vampire the way it affects humans I could be wrong, I would re-read breaking dawn and pay attention to Nessie.

I think it would either have no effect (a venom immunity) অথবা could possibly make her slightly আরো vampiric. Maybe make her become venomous?

I don't think it'd kill her like it does werewolves, though that idea was suggested in the books. The similarities between the two are too superficial. I couldn't see where venom fatality would come from.
