I get a flu shot each year and had the pneumonia vaccine a number of years ago. About fifteen years ago, when I was a "healthy guy", I had shingles. It hurts like hell. Ecyclovir, Denavir, Dermboro and oxycontin were my friends. It put me out of work for over a week. I highly recommend the shingles vaccine for anyone who doesn't have an allergy to it. It's something you don't want to catch. I had pain for over a year but it wasn't severe.
BTW: If you have never had chicken pox you will not get shingles and do not need the vaccine. Also, the vaccine is only about 60% effective. That means that if you do get the vaccine you still have a 40% chance of getting shingles.
It is also "possible" to get shingles from the shingles vaccine.
