I had chicken pox when I was young, but I have had shingles twice! My first bout with them I was in my 40's and the next time I was 50. I have several health problems and my dr said they usually don't give the vaccine unless you are over 60, but in my case, I need to go ahead and have the vaccination. I haven't had it yet, but I still get the itches in the area on my back where they were.
