- Indication: Protection against varicella and herpes zoster - Study Objectives - Primary: Safety and tolerability assessment after single dose administration of NBP608 - Secondary: immunogenicity assessment after single dose administration of NBP608
This study evaluates the immunogenicity and safety of three different potencies of NBP608 and Varivax which are indicated for active immunization for the prevention of varicella. Total of 152 subjects (38 subjects per each treatment arm) of 12 months to 12 years of age are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned.
This study assesses non-inferiority by comparing seroconversion rate of NBP608 to Varivax which are indicated for active immunization for prevention of varicella. Total of 488 subjects (244 subjects per treatment arm) of 12 months to 12 years of age are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned.
The purpose of this study is to evaluate the protective effect, safety and immunogenicity of a live attenuated varicella vaccine in healthy children.
The purpose of this study is to evaluate the safety of a live attenuated varicella vaccine in healthy adults, adolescents, and children.
Varicella zoster virus (VZV) can lead to significant morbidity and mortality in transplant recipients. Current recommendations suggest a 4 week waiting period between vaccination and transplantation and consideration of booster immunizations if antibody response does not reach target levels. This four week waiting period can result in delayed transplant, rejection of an optimal organ, or missed opportunity to vaccinate. However, these recommendations are not evidence based. This is a prospective study to look at the immune response to varicella vaccine in children with chronic liver disease. Investigators will evaluate: 1. the time at which VZV DNA becomes undetectable in blood and saliva by PCR after vaccination in children with chronic liver disease and 2. the difference in humoral and cell mediated immune response to varicella immunization between children with chronic liver disease and healthy children.
The purpose of this study is to evaluate the safety and immunogenicity of 2 formulations of GSK Biologicals' varicella vaccines given as a 2-dose course in the second year of life.
The purpose of this study is to investigate whether there is an association between stroke or heart attack and reactivation of varicella zoster virus, measured by antibody levels, using linked data from the Health Survey for England and secondary care.
The re-activating nature of Varicella Zoster Virus (VZV) may allow life long boosting when used as a vaccine vector in conjunction with HIV to generate durable immunity systemically and at the mucosa. This study aims to characterize mucosal immunity before and after vaccination with a commercial live-attenuated varicella-zoster virus vaccine with respect to immune activation state, mucosal homing properties and VZV-specific effector immune responses in healthy women at low risk for HIV acquisition.
