A Study of Intradermal Administration of ZOSTAVAX™ (V211-051 AM2)

A Partially Blinded Randomized Clinical Trial to Study the Immunogenicity and Safety of Intradermal Administration of ZOSTAVAX™ (V211)

This study will compare the safety and immunogenicity of ZOSTAVAX™ (V211) administered both intradermally and subcutaneously at various doses.

This is an exploratory, randomized, partially blinded, multicenter clinical study designed to compare safety and biomarkers of varicella zoster virus immunogenicity when administering ZOSTAVAX™ (V211) at various doses both intradermally and subcutaneously in healthy male and female participants 50 years of age and older.

Inclusion Criteria:

• Temperature less than 100.4 °F on day of vaccination
• Female participants of reproductive potential must have a negative pregnancy test and agree to remain abstinent or use two acceptable contraceptive methods for 3 months postvaccination
• In good health

Exclusion Criteria:

• History of hypersensitivity reaction to any vaccine component, including gelatin or neomycin

• Household or workplace exposure to children 18 months and younger who have not been vaccinated against varicella
• Prior history of herpes zoster
• Prior receipt of any varicella or zoster vaccine
• Received or is expected to receive immune globulin and/or blood products from 5 months prior to randomization through 42 days after vaccination
• On immunosuppressive therapy
• Known or suspected immune dysfunction
• Received a live virus vaccine or is scheduled to receive a live virus vaccine from 4 weeks prior to study vaccination through the completion of all study visits
• Received any inactivated vaccine or is scheduled to receive any inactivated vaccine from 7 days prior to study vaccination through 7 days postvaccination, except for inactivated influenza vaccine
• Not ambulatory
• Pregnant or breastfeeding
• Use of nontopical antiviral therapy with activity against herpes viruses
