NCT ID: NCT05928455 Active, not recruiting - COVID-19 Clinical Trials

The Immunogenicity and Safety Following a Heterologous Booster Dose of Recombinant SARS-CoV-2 Vaccine LYB001

Start date: May 14, 2022
Phase: Early Phase 1
Study type: Interventional

The goal of this clinical trial is to assess the immunogenicity and safety following a heterologous booster dose of recombinant SARS-CoV-2 vaccine (CHO cell) LYB001 in adults 18-59 years of age completed two- or three-dose inactivated COVID-19 vaccine. The main questions it aims to answer are: - whether LYB001 group is better on immunogenicity than the control group of inactivated vaccine? - whether LYB001 group has better performance on safety than the control group of inactivated vaccine, such as the lower adverse reaction rate?

NCT ID: NCT05923333 Recruiting - Hiv Clinical Trials

B. Infantis Supplementation to Improve Immunity in Infants Exposed to HIV

BifIID
Start date: August 11, 2023
Phase: N/A
Study type: Interventional

The primary objectives of this study are to evaluate the effect of early-life B. infantis Rosell®-33 supplementation in infants exposed to HIV on: - gut microbiome composition and diversity at 4 weeks of life - markers of intestinal inflammation and microbial translocation at 4 weeks of life - Th1 cytokine responses to BCG at 7 weeks and 36 weeks of life The secondary objectives include to evaluate the effect of B. infantis Rosell®-33 supplementation on: - longitudinal succession of the gut microbiota composition, diversity and function - relative and absolute abundance of B. infantis in infant stool during the first 36 weeks of life - stool metabolome - T cell subset ontogeny during the first 9 months of life. Exploratory objectives are to evaluate whether B. infantis Rosell®-33 supplementation improves: - infant growth - all-cause morbidity - neurodevelopment during the first 9 months of life - antibody responses to early childhood vaccines

NCT ID: NCT05870631 Not yet recruiting - Vaccine Reaction Clinical Trials

Immunogenicity and Safety of DTaP or DT Vaccine in 6 Year Old Children ( DTaP/DT )

DTaP/DT
Start date: May 2023
Phase: Phase 4
Study type: Interventional

This study is to evaluate the immunogenicity and safety of DTaP or DT given in children aged 6 years.

NCT ID: NCT05870618 Not yet recruiting - Vaccine Reaction Clinical Trials

Immunogenicity and Safety of DTaP or DT Vaccine in 6 Year Old Children

DTaP/DT
Start date: May 2023
Phase: Phase 4
Study type: Interventional

This study is to evaluate the immunogenicity and safety of DTaP or DT given in children aged 6 years.

NCT ID: NCT05869201 Completed - Influenza Clinical Trials

Tolerability, Safety and Immunogenicity Trial of the Flu-M Quadro, Tetravalent Inactivated Split Influenza Vaccine

Start date: October 6, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

The goal of this clinical trial is to assess tolerability, safety and immunogenicity of the Flu-M Quadro vaccine as compared to the Ultrix® Quadri vaccine in volunteers aged between 18 and 60. Participants were given Flu-M Quadro [inactivated split influenza vaccine] with preservative or Flu-M Quadro [inactivated split influenza vaccine] without preservative or Ultrix® Quadri vaccine.The volunteers of each group were vaccinated with a single dose vaccine. Researchers assessed the tolerability, safety and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine. Researchers performed a comparative assessment of the tolerability, safety, and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine and the Ultrix® Quadri vaccine.

NCT ID: NCT05825651 Recruiting - COVID-19 Pandemic Clinical Trials

Long COVID and Its Associations With Health Outcomes in Older Adults

Start date: April 24, 2023
Phase:
Study type: Observational

The Peking University Health Cohort in Anning, Yunnan (PKUHC-AN) is a prospective cohort study carried out in Anning, Yunnan. The primary aim of this study is to investigate the impact of COVID-19 on older adults' health, and to provide high-quality evidence of real world research for the optimization of prevention and control strategies of COVID-19 and other emerging infectious diseases. Data will be collected regarding health status, history of COVID-19 infections and vaccines, lifestyle and socioeconomic characteristics, as well as the short- and long-term health outcomes.

NCT ID: NCT05749926 Active, not recruiting - COVID-19 Clinical Trials

Immunogenicity and Reactogenicity of the Beta-variant Recombinant Protein Booster Vaccine (VidPrevtyn Beta, Sanofi) Compared to a Bivalent mRNA Vaccine (Comirnaty Original/Omicron BA.4-5, BioNTech-Pfizer) in Adults Previously Vaccinated With at Least 3 Doses of COVID-19 mRNA Vaccine

CoviBOOST 2
Start date: May 16, 2023
Phase: Phase 3
Study type: Interventional

The objective of this trial is to compare the immunogenicity and the safety of the Beta-variant recombinant protein booster vaccine (VidPrevtyn® Beta, Sanofi) to a bivalent mRNA vaccine (Comirnaty Original/Omicron BA.4-5, BioNTech-Pfizer) in adults previously vaccinated with at least 3 doses of COVID-19 mRNA vaccine. The results will provide important data for the future COVID 19 vaccine strategy. A biobank will also be set up to evaluate the protection conferred by one or other of these vaccines as booster in the event of the emergence of new variants in the future.
