Yep it is possible to have chicken pox multiple times, I have. I had it when I was a young child and then I had it again when I was 19 years old. Both times were full blown cases too. And don't forget, that once you have had chicken pox you always have the virus in your body and later in life when you are older you can have Shingles because of it. You can also have shingles more than once. Good Luck
