For someone who had chicken pox in the early twenties, do I still need Varicella vaccination?

Chickenpox is a virus that hides inside our body forever. It hides in the nerve cells, and sometimes when your immunity is poor, it can flare up and become shingles/zoster.

Our body will continue to produce antibodies (immunity) to control the virus. There is no need to get a chickenpox vaccine in this case.
