Shingles Support Group
Herpes zoster, colloquially known as shingles, is the reactivation of varicella zoster virus, leading to a crop of painful blisters over the area of a dermatome. It occurs very rarely in children and adults, but its incidence is high in the elderly (over 60), as well as in any age group of immunocompromised patients.
-------------------------------------
ZOSTAVAX (Zoster Vaccine Live) is given as a single shot. ZOSTAVAX cannot be used to treat Shingles, or the nerve pain that may follow Shingles, once you have it. The need for revaccination has not been established.

This site can answer a lot of questions. The company, Merck, probably would like to sell more shots, but, they themselves state that the need has not been established.
That's a good decision, to ask your doctor. But if you hang around this support group long enough, you'll find that MikeWhite hits the nail on the head more often than most doctors do. :)
