I Have Had Shingles Probably 10 Times Over Many Years.

I have had shingles probably 10 times over many years. My doctor said not to get the shingles shot. That was for the old vaccine. Now they say it is safe for me to have the shot with the new vaccine. I am not a squeemish person, but I am wondering what a person like me might experience with the new shingles vaccine, and can it make the shingles come back even worse?
