From the above it appears that one *can* get shingles more than once. I had wondered about that, but never checked on it.

I got shingles maybe 30 years ago. It was probably not as bad a case as some get - I got a patch of 'burned' skin about the size of an envelope on my ribcage. I remember that cloth touching it was painful.
It was the doctor who identified it- until then I had thought that somehow something steeped in acid or some other corrosive thing had lain against my skin.

And until this moment I didn't even know one could get a vaccination against it.
