Filter by:This Phase 3b study is being conducted for the purpose of registration of the GSK208136 vaccine in Korea.
This study is undertaken to evaluate the effectiveness of currently licensed varicella vaccines under conditions of routine use in a setting where varicella vaccine is included in the childhood immunization calendar.
The purpose of this observer blinded study is to provide information on vaccine immunogenicity and reactogenicity in comparison with the US standard of care (ProQuad®) when administered with Hepatitis A vaccine and Pneumococcal vaccine.
The aim of this study is to evaluate a modified formulation of GSK Biologicals' live attenuated varicella vaccine. In vivo pre-clinical data show this change has no negative impact on vaccine safety. This present study is undertaken to rule out any negative impact on the immunogenicity and safety of GSK Biologicals' live attenuated varicella virus vaccine.
Primary objective: To describe the safety profile of a second dose of ProQuad® manufactured with recombinant human albumin (rHA) when administered to children in their second year of life. Secondary objectives: To describe the safety profile of a first dose of ProQuad® manufactured with rHA when administered to children in their second year of life.
This study will evaluate the safety and immunogenicity of a heat-treated VZV vaccine in autologous or allogeneic hematopoietic cell transplant (HCT) recipients, human immunodeficiency virus (HIV)-infected participants with a baseline cluster of differentiation 4 (CD4) cell count ≤200 cells/mm^3, participants with solid tumor malignancy (STM; breast, colorectal, lung, or ovarian malignancies) receiving chemotherapy, and participants with hematologic malignancy (HM; leukemia or leukemia-like disease, lymphoma or lymphoma-like disease, or multiple myeloma). The primary hypothesis is that the heat-treated VZV vaccine will elicit significant VZV-specific immune responses measured by either glycoprotein-based enzyme-linked immunosorbent assay (gpELISA) or VZV gamma interferon enzyme-linked immunospot (IFN-ELISPOT) at 28 days post dose vaccination 4 in, HIV-infected participants, participants with STM, and participants with HM. The primary immunogenicity objective and endpoints were considered by the protocol as exploratory for the autologous and allogeneic HCT groups.
Varicella is a vaccine-preventable disease, which can be severe in immunosuppressed children. Currently, the (live) vaccine is not recommended in pediatric orthotopic liver transplant recipients. Furthermore, protection due to naturally acquired immunity to VZV or post-immunization isn't well described in this population.The questions asked are: - What is the influence of the immunosuppression required after orthotopic liver transplantation (OLT) on the maintenance of VZV-specific immunity elicited by wild-type varicella infection before OLT transplantation? - What is the influence of the immunosuppression required after OLT on VZV-specific immunity elicited by varicella immunization before OLT transplantation? - What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the induction of VZV-specific B and T cell responses elicited by VZV vaccination after OLT transplantation? - What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the persistence / waning of B and T cell responses elicited by VZV vaccination?
Primary objective: To describe the safety profile of a refrigerator-stable formulation of VARIVAX® as a first single dose injection in 12 to 15 month-old infants in the 42-day follow-up period post-vaccination. Secondary objectives: NA
Primary objective: To compare if, when given concomitantly with VARIVAX® by the same route at 12-18 months of age using separate injection sites, a single dose of M-M-RTMII administered by IM route is as immunogenic as a single dose of M-M-RTMII administered by SC route in terms of response rates to measles, mumps and rubella at 42 days following the vaccination. AND/OR To compare if, when given concomitantly with M-M-RTMII by the same route at 12-18 months of age using separate injection sites, a single dose of VARIVAX® administered by IM route is as immunogenic as a single dose of VARIVAX® administered by SC route in terms of response rate to varicella at 42 days following the vaccination Secondary objectives: - To summarise the antibody titres to measles, mumps, rubella and varicella at 42 days following the vaccination in children immunised with M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC, - To evaluate the safety profiles of M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC.
Primary Objective: - To demonstrate that ProQuad® can be administered concomitantly with a booster dose of Infanrix® hexa to healthy children 12 to 23 months of age without impairing either the antibody response rates to measles, mumps, rubella, varicella, hepatitis B and Haemophilus influenzae type b; or to the 3 pertussis antibody titres measured at 42 days following vaccination. Secondary Objectives: - To describe the antibody titres and the antibody response rates to measles, mumps, rubella, varicella, diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b as measured at 42 days following vaccination by an Infanrix® hexa primary series schedule and all data are pooled. - To evaluate the safety profile of ProQuad® when administered concomitantly with a booster dose of Infanrix® hexa by an Infanrix® hexa primary series schedule and all data are pooled.
