Brief summary: This study assesses non-inferiority by comparing GMR(Geometric Mean Ratio) of NBP608 to Zostavax which are evaluated by gpELISA (Glycoprotein Enzyme Linked Immunosorbent Assay). Total of 824 healthy subjects (412 subjects per treatment arm) aged 50 and over are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned.

Detailed description: This is a multi-center, randomized, double blinded, parallel-group study to assess the Immunogenicity and safety of NBP608 compared to Zostavax which are indicated for the prevention of herpes zoster. Total of 824 healthy subjects aged 50 and over are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned in 1:1 ratio. Stratified randomization for age group is used to achieve the balance of treatment assignment within age strata.

Total of five visits are scheduled including two visits via telephone contact. Blood sampling is conducted for immunogenicity assessment before and 6 weeks after vaccination at Visit 2 and Visit 4 respectively. Safety is monitored 1 week, 6 weeks and 26 weeks after vaccination through Visit 3\*, Visit 4 and Visit 5\* (\* telephone contact)

Eligibility criteria: Inclusion Criteria:

* Healthy adult over aged 50 years
* Menopause females or females who are confirmed to be negative in a preganacy test on the day of screening and agree to practice birth control for 6 weeks after signing informed concent

Exclusion Criteria:

* Those with hypersensitivity to any component of IP(Investigational Product), such as gelatin
* Those with a history of hypersensitivity to vaccination, such as Guillain-Barre syndrome
* Those who have received antiviral agents witin 1 month prior to IP vaccination (topical antiviral agent is allowed)
* Those who have previously received herpes zoster vaccine
* Those who have a history of herpes zoster
* Those with congenital or acquired immunodeficiency
* Those with active untreated tuberculosis
* Those who have received blood products or immunoglobulin within 3 months prior to IP(Investigational Products) vaccination
* Those who have received other IPs(Investigational Products) in another clinical study witin 4 weeks prior to IP vaccination in this study
