Active clinical trials for "Herpes Zoster"

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.

Since measles-mumps-rubella (MMR) and varicella vaccinations are established as routine childhood practice and often co-administered during the second year of life, a combined measles-mumps-rubella-varicella (MeMuRu-OKA) vaccine is fully justified. Such a combined vaccine was developed and extensively studied in susceptible children. In countries where varicella mass-vaccination is already implemented, a transition period is necessary as children who started with separate first-dose vaccinations of MMR and varicella will receive a single shot of the combined vaccine as the second dose. To account for those situations, this study will evaluate the effect of the combined measles-mumps-rubella-varicella vaccine given in place of separate MMR and varicella vaccines as a second dose.

As measles-mumps-rubella (MMR) vaccination is established as routine childhood practice in most industrialised countries and varicella vaccination is now being introduced in many countries during the second year of life, a combined measles-mumps-rubella-varicella vaccine was developed for administration convenience and improved compliance to vaccination. To account for situations where children have received a first dose of MMR vaccine without varicella, this study will evaluate the effect of the combined measles-mumps-rubella-varicella vaccine given in place of the second dose of MMR vaccine. A second dose of the monovalent varicella vaccine will be given to all children participating to this trial since there is a current debate on the need of a second dose to induce a full protection against varicella.

Primary objective: Immunogenicity To demonstrate that a second dose of ZOSTAVAX® elicits higher varicella-zoster virus (VZV) antibody titres than a first dose of ZOSTAVAX® whether given as a 0-1 month schedule or as a 0-3 month schedule in subjects ≥70 years of age as measured at 4 weeks post-vaccination Secondary objectives Immunogenicity To summarise the VZV antibody titres at 4 weeks post-vaccination after a 1-dose regimen and 4 weeks post-vaccination after each dose of each 2-doses regimen of ZOSTAVAX®. To compare the VZV antibody titres at 12 months after completion of a 1-dose regimen with the VZV antibody titres at 12 months after completion of each 2-doses regimen of ZOSTAVAX® To summarise the VZV antibody titres at 24 and 36 months after completion of a 1-dose regimen and at 24 and 36 months after completion of each 2-doses regimen of ZOSTAVAX®

The purpose of this study is to determine whether Zoster Vaccine Live and Pneumococcal Vaccine, polyvalent are as well tolerated and immunogenic when the vaccines are given together (in different body sites), as when they are given alone, in adults 60 years of age and older.

The purpose of this study is to determine whether the investigational zoster vaccine has a comparable immune response (the body's ability to protect against disease) and safety profile when given concomitantly with another vaccine.

The incidence and severity of HZ (or shingles), as well as the frequency and severity of its complications, increases markedly with increasing age. More than half of all cases occur in persons over the age of 60. Even without complications, HZ can interfere with an elderly patient's ability to perform essential activities of daily living, resulting in a loss of independence that is emotionally devastating and frequently irreversible. The most common complication of HZ in elderly persons is postherpetic neuralgia (PHN), which frequently results in disordered sleep, chronic fatigue, anxiety and severe depression. Antiviral therapy has a modest impact on the acute phase of HZ. However, it does not appear to prevent the development of PHN. This study is a 5.5 year randomized, double-blind, placebo-controlled, efficacy trial to determine whether vaccination with live-attenuated Oka/Merck varicella-zoster decreases the incidence and/or severity of herpes zoster (HZ) and its complications in adults 60 years of age and older.

Varicella-zoster virus (VZV) is a herpesvirus that causes two distinct clinical syndromes. Primary infection is manifested as varicella (chickenpox) , whereas reactivation of latent VZV results in a localized eruption known as herpes zoster. The investigational vaccine of this study is produced by Changchun BCHT biotechnology Co. It's a live attenuated herpes zoster vaccine based on the production process of live attenuated chickenpox vaccine.This study plans to have 25000 adults aged 40 years or older and involves in a randomized, double-blind, placebo-controlled trial . The primary outcome is to evaluate the efficacy of the vaccine against herpes zoster 30 days after vaccination and the safety of the vaccine.

The purpose of this study is to assess immunogenicity, reactogenicity and safety of GSK Biologicals' HZ/su vaccine when its first dose is co-administered with the FLU-D-QIV vaccine in adults aged 50 years or older compared to administration of vaccines separately.

In this study the investigators are trying to identify immune signatures that are associated with effective or poor vaccine responses to naturally-acquired herpes zoster virus and the zoster (shingles) vaccine, Zostavax.
