A Lot-to-Lot Consistency Study to Evaluate Safety, Tolerability, and Immunogenicity of Inactivated Varicella Zoster Virus (VZV) Vaccine in Healthy Adults (V212-014)

Phase 3
Withdrawn
Conditions
Herpes Zoster
Interventions
Biological: V212 Lot 1
Biological: V212 Lot 2
Biological: V212 Lot 3
Registration Number
NCT02180295
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The study will evaluate the consistency of 3 lots of inactivated VZV vaccine for safety, tolerability, and immunogenicity in healthy adults. The primary hypothesis of the study is that the 3 lots of inactivated vaccine will demonstrate similar immunogenicity at 28 days after the fourth dose.
