Thanks Lady. I guess it's back to my analogy of the lottery because having shingles once most definitely does not preclude you from having them again.

I know it's a different strain of the herpes virus, but it's a bit like saying once you've had a cold sore you'll build up immunity and not get another one.

I do thank you for posting the information though. It's good to have as much info as possible to enable you to make an informed decision.
