چکیده

Herpes zoster (shingles), a painful and disabling disease, affects an estimated 1 million individuals in the United States annually and results in significant morbidity, lost productivity, and diminished quality of life. Herpes zoster constitutes the reactivation of varicella-zoster virus (VZV), the same virus that causes chickenpox. After resolution of chickenpox, VZV remains dormant in dorsal root ganglia. Varicella-zoster-specific cell-mediated immunity wanes naturally with advancing age or earlier in the setting of an altered immune status, which can result in the reactivation of VZV as herpes zoster. The pain associated with the rash caused by herpes zoster is often described as burning, stabbing, itching, or aching. Postherpetic neuralgia, the most common complication of herpes zoster, occurs after the zoster rash has resolved, affecting up to a third of patients. Herpes zoster is associated with significant morbidity, especially in the elderly. Herpes zoster is both more common and more severe among older adults. In both acute herpes zoster and postherpetic neuralgia, pain is the primary cause of morbidity.

After the initial infection (chickenpox) or vaccination, the virus remains inactive or latent in the dorsal root ganglia (DRG); when decreasing cell mediated immunity (CMI) occurs, the virus is reactivated from a latent phase to a lytic phase and frequently repl...

A vaccine to prevent herpes zoster and post-herpetic neuralgia in older adults.

BACKGROUND The incidence and severity of herpes zoster and postherpetic neuralgia increase with age in association with a progressive decline in cell-mediated immunity to varicella-zoster virus (VZV). We tested the hypothesis that vaccination against VZV would decrease the incidence, severity, or both of herpes zoster and postherpetic neuralgia among older adults. METHODS We enrolled 38,546 a...
