Yes, you must have had chicken pox to get shingles (Herpes zoster)

When you are originally infected with Varicella (chicken pox), preferably as a child, the virus stays dormant in 33 pairs of dorsal root ganglia and 12 pairs of cranial nerve ganglia for the rest of your life. At some later point in that life, either due to concurrent illness, immunosuppression, stress, or just age, the virus can "crawl" down one of those nerves and cause the classic shingles skin breakout in just one dermatome. (You can actually have 2 adjacent dermatomes affected, but anything more is disseminated Zoster, in which case make sure your will is up to date.)

Now, there will be people who claim they got Zoster but never had chicken pox. In reality, 90+% of the population know they had it, and of the 10% who don't think they had it, 95% will have Varicella antibodies. The 0.5% of the population that actually never had chicken pox CANNOT get shingles. Also, know this---you can't get shingles from someone with shingles, you can only get primary chicken pox if you are not immune.

Question: Can one have natural immunity to chickenpox even though they have never had chickenpox or been vaccinated?
