So far as I can tell, I'm not yet eligible for this because my 70th birthday is next June.
What happens if you've never had chicken pox and you are vaccinated against shingles?
So far as I am aware, I've never had chicken pox. My children have, and I didn't catch it from them, so it's possible I might have done. I certainly don't remember having it as a child, my mother died 19 years ago, so I can't ask her. At the sort of age I might have caught it and not remembered, she had her hands full with my severely disabled oldest brother: he had muscular dystrophy and died when he was 18, shortly before my 6th birthday, so I would not be at all surprising if I caught it some time in my first 6 years and no-one remembered.
