Immunization Update 2007 Satellite Broadcast/Webcast August 9, 2007 Zoster Vaccine Segment Graphics subject to change. This material in the public domain.
Herpes Zoster (Shingles) • Caused by reactivation of varicella zoster virus • Can occur years or decades after illness with chickenpox • Generally associated with normal aging and with anything that causes reduced immunocompetence • Lifetime risk of up to 30% in the United States • Estimated 500,000 to 1 million cases of zoster diagnosed annually in the U.S
Complications of Herpes Zoster • Postherpetic neuralgia (can persist for weeks or months after rash resolves) • Ophthalmic zoster (involvement of the ophthalmic division of the trigeminal nerve and the eye) • Dissemination with generalized skin eruptions and involvement of the central nervous system, lung, liver, and pancreas
Herpes Zoster Vaccine (Zostavax) • Contains live attenuated varicella virus in an amount that is approximately 14 times greater than that in regular varicella vaccine • Approved for persons 60 years and older • Administered by the subcutaneous route
Herpes Zoster Vaccine Trial • Compared with the placebo group the vaccinated group had • 51% fewer episodes of zoster • Less severe disease • 66% less postherpetic neuralgia • No significant safety issues identified Source: NEJM 2005;352(22):2271-84.
ACIP Recommendations* for Zoster Vaccine* • Single dose of zoster vaccine for adults 60 years of age and older whether or not they report a prior episode of shingles • Persons with a chronic medical condition may be vaccinated unless a contraindication or precaution exists for their condition *Provisional recommendations, October 2006
Screening for Zoster Vaccine Eligibility • Screening for a history of varicella disease is NOT necessary or recommended to administer zoster vaccine to a person 60 years of age or older • Persons born in the U.S. before 1980 can be assumed to be immune regardless of their recollection of chickenpox
Screening for Zoster Vaccine Eligibility • Do NOT test the person for varicella antibody • A negative test is more likely to indicate waning antibody level rather than true susceptibility • Seronegative persons should receive 2 doses of single antigen varicella vaccine
Zoster Vaccine Storage and Handing • Must be stored at 5o F (-15o C) or colder AT ALL TIMES • Protect from light • Administer within 30 minutes of reconstitution
