Virginia creeper and poison ivy are not related at all, and as you likely just read, VC does not contain urushiol. On the other hand, if you had a mom that put Bacteen on every little scratch, was always fastidious about hygene, and never let you play in the mud(etc.) outside, well then you're likely allergic to a lot more things then the rest of us.
If your allergic to the many varieties of the houseplant Dieffenbachia, then you might also be allergic to VC. They have the same oxalate crystals. And of course, don't eat the berries.
