Here is another PSA (info from my doc):
My understanding is that until recently, the shingles vaccine was not terribly effective. Perhaps only 60%. My uncle had the vaccine and STILL got shingles. So don't kick yourself too hard for not getting it. It may have not made a difference.
There is a new vaccine that has just become available. It is in the order of 80-90% effective.
So if you eschewed the vaccine before because of ineffectiveness, this may be your time.
I had shingles when I was about 27 years old and it SUCKED. I intend to get the new vaccine.
