Why do some people say they aren't allergic to poison ivy/oak/sumac? Are some people immune or just lucky?

In brief: Poison Ivy

Some people appear to be immune, others become immune.
However, you can gain or lose immunity, so to assume you can't get it if you never have before is foolish. People change as they age. I would never assume that i was immune at any time no matter what my past experience was.
