16 Clinical Trials for Various Conditions
Varicella zoster virus causes chickenpox in children and shingles in adults. Chickenpox is usually a self-limiting illness characterized by fever and a rash. Serious complications can include secondary bacterial infections, pneumonia, and encephalitis. Anti-viral treatment is not a standard of care in immunocompetent children, but is recommended whenever a risk of complication exists. This study will evaluate the safety and blood levels of a new formulation of famciclovir in children 1-12 years of age.
Chickenpox, Herpes Zoster
To evaluate the effect of intramuscular RZV vaccine on VZV-specific skin TRM and circulating T-cells
Varicella Zoster Virus Infection
The purpose of this clinical study is to learn about the safety, extent of the side effects (reaction to vaccine), and immune response (your immune system's reaction) of the study vaccine called Varicella Zoster Virus modRNA (VZV modRNA). We are seeking for healthy participants 50 through 85 years of age. This study will be conducted in 2 substudies: Substudy A (Phase 1) and Substudy B (Phase 2). Substudy A: This substudy is the Phase 1 portion of the study. In this substudy, participants will receive 1 of 3 VZV modRNA vaccine candidates (different construct, different dose levels and different formulation \[frozen or freeze dry powder\]) or the approved shingles vaccine intramuscularly. Participants will be assigned in 1 of 10 groups in the study. Vaccination will be given either as a 2-dose series using one of two dosing schedules (either 2-months apart or 6-months apart), or (in one of the groups), as a single VZV modRNA vaccine at the first vaccination visit and saline at the second vaccination visit. Participants will take part in this study for 8 to 12 months depending on the group they are assigned to. Some group(s) will continue into persistence-of-immunity (overtime assessment of effect of vaccine) portion of the study. Those participants assigned to these selected groups will be involved in the study for up to 5 years. Substudy B: This substudy is the Phase 2 portion of the study. In this part of the study, participants will receive either VZV modRNA vaccine at selected dose level/schedule/formulation or approved shingles vaccine. This selection was determined from data collected in Substudy A. Participants will be involved in this study for up to 5 years.
Shingles, Herpes Zoster Infection, Human
The study will evaluate the safety, tolerability, and immunogenicity (your immune system's reaction) of the study vaccine called Herpes Zoster IN001 mRNA Vaccine (IN001) in healthy participants who are between 50 and 69 years of age
Herpes Zoster
The objective of this study is to prevent reactivation of herpes zoster during the first year after transplant.
VZV Infection After Bone Marrow Transplantation
Background: * The common varicella-zoster virus causes both chickenpox and shingles. Both diseases cause rashes, but they can also have complications such as bacterial infections of the skin, pneumonia, or eye disease. * By drawing and studying blood samples from people who have been infected with the varicella-zoster virus or who are receiving or have received the varicella vaccine, researchers hope to learn more about the immune system s response to the virus. Objectives: - To determine the immune system s response to the varicella virus, either in its existing form or given as part of a vaccine. Eligibility: * Individuals 18 years of age and older who have had or are receiving the varicella vaccine. * Individuals 5 years of age and older who currently have chickenpox or shingles. Design: * Participants will visit the NIH Clinical Center for an initial physical examination, and will provide blood samples for evaluation. * Researchers will determine the number of samples to be taken and the amount of blood to be drawn as needed based on the participants medical history and exposure to the varicella-zoster virus. Investigators in this study will not be giving subjects either the chickenpox or shingles vaccine. They will only be looking at the response to the vaccine in persons who are receiving or have received the vaccine from their health care provider.
Chickenpox, Herpes Zoster
To provide oral sorivudine ( BV-araU ) to pediatric HIV-infected patients with varicella-zoster viral disease who have failed or are intolerant of alternative therapy.
HIV Infections, Chickenpox
To determine the efficacy of oral 882C87 compared with oral acyclovir in the treatment of localized herpes zoster in immunocompromised patients. To assess the safety and tolerance of oral 882C87 in immunocompromised patients.
HIV Infections, Chickenpox
The purpose of this study is to see if the varicella-zoster virus (VZV) vaccine will be safe and if it can help prevent shingles in HIV-infected children who have already had chickenpox. VZV is the virus that causes chickenpox. If this virus is reactivated in the body, it can also cause shingles. Shingles is common in children with HIV who have had chickenpox, although it is usually not life-threatening. The VZV vaccine used in this study may be able to prevent HIV-positive children who have had chickenpox from developing shingles.
HIV Infections, Chickenpox
The goal of this clinical trial is to assess the safety and immunogenicity of an srRNA-based vaccine, JCXH-105, in the prevention of Herpes Zoster (Shingles). Subjects will be randomized to receive either JCXH-105 or Shingrix.
Herpes Zoster (HZ), Infectious Diseases, Shingles
The goal of this clinical trial is to assess the safety and immunogenicity of a self-replicating (sr) RNA-based vaccine, JCXH-105, in the prevention of Shingles (Herpes Zoster) Participant will be randomized to receive either JCXH-105 or Shingrix.
Herpes Zoster (HZ), Shingles, Infectious Disease
To compare the efficacy of oral sorivudine (brovavir) and oral acyclovir for the treatment of localized herpes zoster in HIV-infected patients. HIV-infected patients are at high risk for herpesvirus infections, including varicella-zoster virus ( VZV ) infections, also called shingles. Acyclovir, an approved drug, is widely used to treat VZV infections in the HIV population. Since no data from controlled studies are available to define the role of antiviral therapy for VZV infections in HIV-infected patients, a study is needed to test the relative efficacy of brovavir, an experimental antiviral drug, versus that of acyclovir.
HIV Infections, Chickenpox
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.
Herpes Zoster, Allergy and Immunology, Corona Virus Infection
The study's aim is to enhance current immunization activities in community pharmacies through targeting the two most commonly available non-seasonal vaccines in community pharmacies, namely pneumococcal and herpes zoster vaccination services. The study will compare the change in the number of pneumococcal and herpes zoster vaccinations administered in pharmacy from the corresponding 6-month period prior to the intervention to the 6-month intervention period between intervention pharmacies and the control pharmacies.
Herpes Zoster, Pneumococcal Infections
Herpes zoster, or shingles, is the result of a viral infection that causes a painful skin rash, usually in older people or people with suppressed immune systems like those infected with HIV. The ZOSTAVAX vaccine has been shown to reduce the number of infections and symptoms of herpes zoster infection in people over the age of 60. The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of two doses of ZOSTAVAX in HIV-1-infected adults with conserved immune function (Cd4+ T cell counts \>=200 cells/uL) virologically suppressed on potent combination antiretroviral therapy (ART).
Herpes Zoster, HIV Infections
This study is a randomized, open-label multi-center evaluation of the tolerability of treatment with NGX-4010 in conjunction with pre-patch topical application of one of three 4% lidocaine-based local anesthetic products. Eligible subjects will have moderate to severe neuropathic pain secondary to painful diabetic neuropathy (PDN), postherpetic neuralgia (PHN) or HIV-associated neuropathy (HIV-AN), with average numeric pain rating scale (NPRS) scores during screening of 3 to 8 (inclusive).
