I had my vaccination a few years ago and now they developed one that is the preferred treatment for shingles. It consists of 2 injections spaced a couple of months apart. If your relatively healthy and in the age group (50 - 60) , you might want to consider it. I had my second and final injection yesterday , and man is my shoulder sore ! It's better than getting shingles and your risk increases as you get older. Just something to think about.
