More than 95% of adults (aged >20 years) born in the United States have immunity to varicella, the vast majority due to primary VZV infection, known as varicella (or chickenpox). Reactivation of latent VZV results in herpes zoster (or shingles). A personâs lifetime risk for herpes zoster is 15% to 20%, with the highest incidence occurring in the elderly and immunocompromised individuals.
Varicella zoster virus is not the same as herpes simplex virus; however, they belong to the same family of viruses. The shingles vaccine decreases the chance of shingles by about half in those between the ages of 50 and 80.It also decreases rates of postherpetic neuralgia, and if an outbreak occurs, its severity.After 80 the vaccine is still effective, just less so.amples of lesions on the skin, eyes, and lung from 182 people with presumed herpes simplex or shingles were tested with quantitative PCR or with viral culture. In this comparison, viral culture detected VZV with only a 14.3% sensitivity, although the test was highly specific (specificity=100%).
