A Phase 3 Study of Revaccination in Subsequent Pregnancies With Bivalent RSV Vaccine and Duration of Protection of a Single Dose
This study aims to check how safe and well-tolerated a second dose of RSVpreF is when given during later pregnancies, and to see how long the immunity lasts from a single dose given during a previous pregnancy by examining the blood of nonpregnant participants who had the vaccine before.
A Study on the Immune Response and Safety of Vaccine Against Respiratory Syncytial Virus Given to Chinese Adults 18 to 59 Years of Age at Increased Risk of Respiratory Syncytial Virus Disease
The study will evaluate the immune response of the RSVPreF3 OA investigational vaccine in Chinese adults 18 to 59 years of age (YOA) who are at increased risk of respiratory syncytial virus (RSV) disease, in comparison with the immune response generated in older adults 60 YOA and above from the …
Genotype and Disease Burden of RSV in Older Vietnamese Adults (RSV: Respiratory Syncytial Virus )
This observational, prospective, multicenter study aims to estimate the proportion of RSV infection in adults aged 60 years and older hospitalized due to acute respiratory infections or exacerbation of cardiopulmonary disease.
Real-world Effectiveness, Safety and Immunogenicity of Chikungunya Vaccination in Populations at Risk of Severe or Complicated Forms: Prospective Study in La Réunion
Against the backdrop of a growing chikungunya epidemic in La Réunion, this prospective study will assess the real-life efficacy, safety and immunogenicity of IXCHIQ® vaccine in vulnerable individuals (seniors, comorbid patients), defined by the French Health Autority (HAS) as at risk of severe or complicated forms and/or chronic disabling forms …
Safety and Immunogenicity of Ervebo® and Zabdeno® Booster Vaccines Against Ebola Virus Following Previous Vaccination with the Zabdeno/Mvabea® or Ervebo® Vaccine Schedules in DRC
The goal of this randomized controlled trial is to investigate whether individuals in DRC previously vaccinated with Zabdeno/Mvabea® or Ervebo® vaccine schedules against Ebola virus can be safely and adequately boosted with homologous or heterologous vaccine schedules. Participants will be randomized to receive either a homologous or heterologous vaccine schedule …
Phase 2 Study of Inhaled SNG001 in Mechanically Ventilated Patients With Respiratory Viral Infection
The goal of this Phase 2 study is to assess about the safety, antiviral biomarker responses and efficacy of SNG001 when given to patients requiring invasive mechanical ventilation due to a respiratory virus infection. Its ability to speed up virus clearance and reduce mortality, compared with standard of care, will …
A Study on the Immune Response and Safety of the Second Dose of an Investigational Chickenpox Vaccine When Given to Healthy Children 3 Months After a First Dose at 12 to 15 Months of Age
The purpose of this study is to evaluate the immune response and safety of GSKs investigational varicella vaccine (VNS Vaccine) compared to an already approved varicella vaccine, Varivax (VV), when administered as second dose to healthy children. 3 months after first dose at 12 to 15 months. The study will …
A Study on the Safety of an Investigational Chickenpox Vaccine, When Given to Healthy Children, 12 to 15 Months of Age
The purpose of this study is to assess how well-tolerated GSK's investigational varicella vaccine (VNS Vaccine) is, in comparison to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted on healthy children aged 12 to 15 months, and who have neither contracted varicella nor received …
A Study on the Immune Response and Safety of an Investigational Chickenpox Vaccine When Given to Healthy Children 12 to 15 Months of Age
The purpose of this study is to assess the consistency of immune response to three different lots of GSK's investigational varicella vaccine (VNS Vaccine), and to compare the safety and immune response of VNS vaccine to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted …
A Study on the Immune Response and Safety of an Investigational Chickenpox Vaccine and a Marketed Measles, Mumps and Rubella Vaccine When Administered as Intramuscular Injection to Healthy Children 12 to 15 Months of Age
This study aims to assess the immune response and safety of GSK's candidate chickenpox and marketed MMR vaccines when given to children 12 to 15 months of age via a muscle injection. It compares the GSK vaccines to Merck's chickenpox vaccine, administered just under the skin. Additionally, the study will …
