This clinical trial is to study the safety and tolerability of a recombinant herpes zoster vaccine (LZ901) and sponsored by Beijing Luzhu Biotechnology Co., Ltd. It is a phase I, randomized, double-blind, placebo-controlled, dose escalation study in healthy people aged 50 to 70 years inclusive. The study is to protect adults against shingles (herpes zoster / varicella zoster virus(VZV)). There will be about 66 participators who will receive two-dose injection at the upper arm. LZ901 vaccine is made up of a tetramer of VZV glycoprotein E (VZV gE-Fc) and adsorbed with aluminum hydroxide adjuvant. This adjuvant can raise the immune response to a lot of antigens. It is the most widely used and safe adjuvant in various types of vaccines worldwide. In this study: 1. The participation is voluntary. 2. Before the study, participants will receive some tests for screening. If qualified, investigators will officially invite them to join this study. 3. The study vaccine is LZ901 with two different dose levels (50μg/0.5 mL, 100μg/0.5 mL). The placebo, which is saline solution, has no active drug. Participants will receive one of three as above mentioned. 4. Participants will be enrolled in one of four cohorts. If participants are enrolled in Cohorts 1 or 2, they will receive LZ901. If participants are enrolled in Cohorts 3 or 4, they will have a 2 out of 3 chance (66%) of receiving LZ901 and 1 out of 3 chance (33%) of receiving placebo. 5. In Cohort 3 and 4, the study staff and participants will not know which study treatment participants will be receiving. However, the study doctor can get this information in case of an emergency. 6. Participants will stay at the clinic for 30 minutes after each vaccination to observe if there are any uncomfortable. 7. This study will last about 8 months and will include about 8 study visits to the clinic. During this period, participants will receive a follow-up phone call and/or email by the study staff to follow the condition closely for safety, and record on diary/contact card. 8. Participants will receive some tests during the study, include safety tests such as physical examination, vital signs measurements, blood tests, urinalysis. Participants will be measured the levels of specific antibodies to see if the vaccine works well. This study is for research purposes only. Participants may not receive any direct benefits from participating in this study but have a chance to be in a study that may help others in the future.
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 immunogenicity and safety of GSK Biologicals' HZ vaccine when its first dose is co-administered with a pneumococcal polysaccharide conjugate vaccine (Prevenar13) in adults aged ≥50 YOA, as compared to the control group where the two HZ/su doses are administered subsequent to Prevenar13.
This study will compare the two vaccines that have been developed to prevent and/or lessen the effects of shingles. One vaccine is live (Zostavax, licensed by FDA) and the other, herpes zoster subunit (HZ/su), contains a piece of the shingles virus (not live) and an ingredient that may enhance the body's immune response to the vaccine, and is currently investigational. The vaccines are being compared to assess their ability to stimulated protection against shingles. The study will provide an opportunity to determine the safety profile of each vaccine in a single trial. The study will also look at the effect of age on the immune response to the two vaccines and on the persistence of these responses.

The VaricElla zosteR VaccinE (VERVE) trial evaluates the safety and effectiveness of the Herpes zoster (HZ) vaccine for shingles, Zostavax, in patients over 50 years old with arthritis and other diseases who are using anti-tumor necrosis factor (TNF) therapy and who have not previously received the vaccine.
The purpose of the study is to learn more abou how the immune system responds to the chickenpox vaccine in adults who had never had chickenpox as a child and were then vaccinated as an adult. The study aims to learn more about the strength and duration of the protection provided by the vaccine in adults, and to observe the immune response to an additional dose of chickenpox vaccine in adults who had received the vaccine at least 5 years earlier. This is especially relevant to workers in a hospital who may be exposed to chickenpox.
Vaccination is the most effective way of preventing infectious diseases. Despite the success of vaccines in general, vaccines induce diminished antibody responses and lower protection in the elderly in particular. This could be explained by a defect in the early responses of an ageing immune system. A better understanding of the basic immunological mechanisms that mediate vaccine efficacy is incomplete. Such information is critical and could greatly decrease both the cost and the time to new vaccine development particularly for the geriatric population. In this trial, the investigators will study the immunologic differences of the FDA approved licensed shingles vaccine between a younger and an older group. Thirty three healthy volunteers between the ages of 25-40 and forty four healthy volunteers between the ages of 60-79 will be enrolled in the study. Each participant in the study will be given one shingles shot. Blood work will be obtained one month before vaccination, on the day of vaccination, one day, three days, seven days, fourteen days, one month, three months and six months after vaccination. Throughout the duration of the study, the participants will be monitored for safety.
The purpose of the study is to evaluate the immunogenicity and safety of Kinrix when co-administered with varicella (Varivax® \[varicella virus vaccine live\], Merck and Company) and (measles mumps rubella) MMR vaccines, compared to Kinrix co-administered with MMR vaccine alone. Both Kinrix and the second dose of Varivax are indicated in children 4-6 years of age, and there is great potential for the vaccines to be given concurrently. The aim of this trial is to demonstrate that co-administered Varivax does not negatively affect the immunogenicity or reactogenicity of Kinrix.
This is a study to evaluate the immune response and safety of GSK Biologicals 2-dose inactivated hepatitis A vaccine when administered with a measles/mumps/rubella vaccine and a varicella (chickenpox) vaccine in children as young as 15 months of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
This research is designed to address the question, "Does the relative deficit in vaccine immunogenicity in extremely premature infants persist beyond the first 6 months of life?" We propose to measure the immunogenicity of varicella and mumps-measles-rubella vaccines in relatively healthy, 12-to-15 month-old children born at \<29 weeks gestation, when compared to full-term infants, as measured by the relevant viral serologies.
The purpose of this study is to see if the MMR and chickenpox vaccines work as well in premature infants as in children that were carried to full term. A group of children who were carried full-term will be matched for age, sex, and race and will be used for comparison.
The purpose of this study is to see if it is safe to give Varivax to HIV-positive children and whether it protects children from infection. Varivax is a vaccine against varicella zoster virus (VZV), the virus that causes chickenpox (varicella) and shingles (zoster). VZV can cause many serious complications in HIV-infected children. Varivax is a VZV vaccine that has been approved for use in healthy children. More research is needed to find out how this vaccine will affect HIV-infected children.
