Most people get immunity for life with a moderate to heavy case of chickenpox as children. If you get a light case, you might not get complete immunity, and if you get it too young - I think it's less than a year old - you run an increased risk of getting it again later in life. I'm hoping my immunity holds out. I had it when I was just shy of three, coming out with the spots on the day my brother was due to be born. (He was three weeks late, and so was spared at that time.) Of course, there are people who do not develop the necessary immunity, and you never know who will be afflicted twice until they're exposed for the second time.
