Filter by:The main objective of this study was to evaluate the immunogenicity and safety of the booster dose of COVID-19 inactivated vaccine and co-immunization with quadrivalent influenza vaccine and 23-valent pneumonia polysaccharide vaccine in people aged 18 years and older. A randomized controlled, open trial design was adopted. The study was conducted with informed consent of the subjects for immunogenicity and safety in the population aged 18 years and older. A total of 3000 healthy subjects were selected, (1)600 healthy subjects were selected for the immunogenicity and safety study of co-immunization, 300 in the adult group (18-59 years old) and 300 in the elderly group (60 years old and above); (2) 2400 healthy subjects were selected for the observational study of the safety of co-immunization, 1200 in the adult group (18-59 years old) and 1200 in the elderly group (60 years old and above ) 1200 people.
To trial the reactogenicity, safety and immunogenicity of the Flu-M inactivated split influenza vaccine in volunteers aged 18-60 years
Live Attenuated freeze-dried Influenza Vaccine has been licensed for use in 2020 (Approval No.S20200002), the sponsor of this research submitted an new application for non freeze-dried Live Attenuated Influenza Vaccine in 2021. The main objective of phase two trail is to evaluate the immunogenicity of LAVI (non freeze- dried). The secondary objective is to evaluate the safety of LAVI (non freeze- dried).
The present study will evaluate the concomitant administration of a Quadrivalent Inactivated Influenza Vaccine with the highest dose level of OVX836 (480µg) tested in the clinic to date, for which the likelihood for interference with Quadrivalent Inactivated Influenza Vaccine is considered the highest.
The study aims to characterize the community burden (including the clinical features) and transmissibility of SARS-CoV-2 within the context of a functional antibody response. In addition,the study will assess the effect of the interaction of SARS-CoV-2 with influenza virus and RSV on disease severity and transmission dynamics. A household-level prospective cohort study will be conducted in one rural and one urban community located in Mpumalanga Province and North West Province, respectively. The study will be conducted for 12 months of intensive follow up (July 2020 to August 2021) with a post-intensive follow-up continuing for a further 16 months (until December 2022). Two hundred households; 1,000 study participants of all ages; will be randomly selected from a list of 327 hoseholds that participated and successfully completed a 10-months follow-up period in a study similar to that currently proposed, but directed at community burden and transmission dynamics of influenza, respiratory syncytial virus and other respiratory pathogens. Each household and household member will be enumerated and the HIV infection status and the level of immunosuppression of HIV-infected individuals will be assessed. Each household member will be followed twice per week during the intense follow-up period (12 months) of the study. During this period upper respiratory tract samples will be collected irrespective of presence of symptoms and data on key symptoms, healthcare seeking, hospitalization and death will be captured at each follow up visit. Respiratory samples will be tested by reverse transcriptase real-time polymerase chain reaction (rRT-PCR) for SARS-CoV-2, influenza and RSV, and selected samples will be cultured and sequenced. An infection risk questionnaire will be administered to all study participants at enrollment and every month thereafter. Sera will be collected at enrollment and every 2 months during the 12-month intense follow-up period from all participants. In addition, sera will be collected every 2 months for a further 6 months following the 12-month intense follow-up period from study participants that tested positive for SARS-CoV-2 by rRT-PCR on respiratory specimens at 14, 16 and 18 months and from all study participants at 18 months. Sera will be tested for the presence of SARS-CoV-2, influenza and RSV antibodies. Wearable proximity sensors will be deployed for 8-12 days in each household over the 6-month intense follow-up period.
Study to assess the efficacy and safety of XC8, film-coated tablets, 10 mg in comparison with placebo in patients with dry non-productive cough against acute respiratory infection.
Study to assess the efficacy and safety of XC8, film-coated tablets, 10 mg in comparison with placebo in patients with dry non-productive cough against acute respiratory infections, and to determine the dosing regimen of XC8, film-coated tablets, 10 mg for treatment of dry non-productive cough against acute respiratory infections.
The study is planned to evaluate the therapeutic efficacy and safety of Ingavirin®, syrup, 30 mg/5 ml, in the treatment of influenza or other acute respiratory infections in children from 6 months to 2 years compared with placebo.
A Multicenter Study Conducted to Evaluate the Performance of the LumiraDx SARS-CoV-2 & FLU A/B Test, and LumiraDx SARS-CoV-2 & RSV Test at Point of Care Testing Sites. Subjects presenting with symptoms suggestive of COVID-19 and/or Influenza and/or RSV will be consented and asked to donate swab sample(s) for testing in the device(s) under evaluation.
Background: Respiratory viruses, like the flu or COVID-19, cause significant illness and death worldwide. Researchers want to collect samples from people with respiratory virus infections. The samples in this natural history study will be used in future research. Objective: To obtain samples from people with respiratory viruses to learn more about respiratory virus infections and the immune responses against them. Eligibility: People aged 3 and older who have or are suspected to have a respiratory virus infection. Design: Participants will be screened with a medical record review. Participants will give blood samples. Data from their medical records will be collected. Participants will give nose samples. A soft plastic strip will be put into each nostril for a minute. They may also give nose, mouth (back of the throat), or saliva samples using swabs. Participants may receive kits by mail to collect nose and blood samples at home. They will use soft plastic strips to collect nose samples. To collect blood, they will prick their finger and dab a few drops of blood on four plastic tips. If a participant is in the hospital, air samples may be collected in their room. Participation will last for up to 2 years. After 2 years, participants may be asked for their consent again to give new samples and new medical data.
