Filter by:This is an open-labelled clinical trial of live attenuated varicella vaccines manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd .The purpose of this study is to evaluate the immunity persistence of the single-dose primary immunization of live attenuated varicella vaccine on different time points ,and the safety and immunogenicity after the booster immunization
Vaccines are used to prevent infectious diseases worldwide. Unfortunately, many vaccines, like the flu vaccine, are less effective in older adults. This single-centre open label partially randomised, partially placebo-controlled trial evaluates the differences in immune response between young and older adults after vaccination with a quadrivalent inactivated influenza vaccine and an adjuvanted herpes zoster vaccination. Exploring the underlying mechanisms between the differences in immunogenicity can provide important information for future vaccine development.
The aim of this study was to evaluate the immune response and safety of both GlaxoSmithKline Biologicals SA's (GSK's) herpes zoster (HZ) subunit (su) vaccine in healthy adults 50 years of age (YOA) and older and quadrivalent seasonal influenza (Flu D-QIV) vaccine in healthy adults 18 YOA and older, when administered sequentially or co-administered with Moderna's mRNA-1273 booster vaccination against COVID-19.
The purpose of this study is to assess vaccine efficacy (VE), ability to generate immune response and safety of two doses of the recombinant subunit zoster vaccine (RZV) for prevention of Herpes Zoster (HZ) in Chinese adults aged 50 years and older.
The aim of the present study is to investigate the safety and clinical utility of contralateral oblique view for fluoroscopic guided cervical epidural access.
The purpose of this study is to measure the effect of the Shingrix vaccine on your immune system and whether that has any effect on the body's ability to fight off other infections such as COVID-19. We hypothesize that: H1: Shingrix vaccination will elevate acute and trained immunity H2: For 6 months following the first injection, increased levels of acute and trained immunity is associated with less disease, including fewer hospitalizations and deaths associated with flu, pneumonia, and COVID-19.
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.
This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.
This is a Phase 1, first in human (FIH), randomised, active-controlled, double-blind study designed to assess the safety and tolerability and explore preliminary efficacy of the EG-HZ vaccine. Oversight will be provided by a Safety Review Committee (SRC).
The study plans to learn more about how the shingles vaccine, Shingrix (SRX), successfully prevents shingles in older people. Two vaccines are currently approved by the Food and Drug Administration (FDA) to prevent shingles. Zostavax is a live virus vaccine which has been available since 2006 and prevents shingles about 50% of the time, though it is less effective the older a person is when they receive it. Shingrix, which was approved by the FDA in 2017, is not a live virus, but has an additive in the vaccine to boost immune response. It is about 97% effective at preventing shingles regardless of a person's age and so far has been effective for at least 4 years after vaccination. Because Zostavax has live virus in it, giving a "challenge" dose of Zostavax - vOka varicella zoster virus - to people who have received both vaccines (Zostavax or Shingrix) in the past, will allow researchers to learn more about how the body works to prevent shingles and how any shingles vaccination helps protect against shingles.
