Filter by:This Phase 2a clinical study is designed to evaluate the immunogenicity and the safety of one dose of OVX836 influenza vaccine administered IM, confirm the dose level and regimen, and expand immunogenicity and safety data to adults through age 65.
The study is designed to assess whether selenium supplementation can boost the immunity response to influenza vaccination in healthy adults. This is a randomized, prospective study enrolling a total of 60 healthy subjects, 18-55 years old.
Researchers are evaluating the safety and effectiveness of a single administration of entolimod when administered at the same time as the influenza vaccine (flu vaccine).
This is a multicenter study with the aim to determine the prevalence of influenza-related invasive pulmonary aspergillosis in Swedish intensive care units and to assess the clinical impact of and risk factors for influenza-related invasive pulmonary aspergillosis
The investigators intend to observe the inflammatory marker procalcitonin (PCT) in comparison with patient variables on morbidity, mortality and antibiotic treatment. The overall aim is to observe if a low PCT value can have potential in reducing unessesary antibiotic use in seasonal influenza patients.
The aim of the study is to identify what sender/signal combinations are most persuasive in encouraging low socioeconomic males living in the U.S. to take-up seasonal flu vaccination. The investigators plan to recruit male subjects and randomly assign them to four persuasion treatments: three of which vary dimensions of the sender of a medical recommendation (racial concordance and authority treatments) and one which varies the signal (standard vs. empathetic). Specifically, the investigators will show subjects videos of either Black or white actors/actresses providing scripted information on the flu vaccination. The investigators will randomize the race of the sender and if the subject is Black, also randomize the authority of the sender, with the actor portraying either a doctor or a layperson. In addition, the investigators will vary the script used in the experiment between one that acknowledges past injustices (indicated as an empathetic script hereafter) and one that does not (indicated as a standard script hereafter). The investigators will provide subjects a free flu shot coupon and elicit the price at which subjects would be willing to give up this coupon for a cash reward. Lastly, in light of the relevance of vaccination take-up in combating COVID-19 pandemic, the investigators will assess demand for information about a COVID-19 vaccine, with subjects invited to receive results of a safety and efficacy review from a trusted or standard source. The design requires the collection of baseline and endline surveys combined with administrative data from pharmacies about coupon redemption. The primary outcomes of interest are posterior beliefs about seasonal flu vaccination, demand and willingness-to-pay (WTP) for a free flu shot coupon, redemption of the coupon, and demand for information about a COVID-19 vaccine.
This study is being conducted to assess the safety, tolerability, and immunogenicity of the live-attenuated CodaVax-H1N1 influenza vaccine as compared to normal saline placebo both administered via intranasal spray to healthy adults.
The primary objectives of the study are: - To describe the safety profile of the different quadrivalent recombinant influenza vaccine (RIV) formulations. - To describe the hemagglutination inhibition (HAI) and seroneutralization (SN) antibody responses against hemagglutinin (HA) (H1, H3, B/Victoria, and B/Yamagata) antigens present in the control vaccine in all groups at all timepoints. The secondary objectives of the study are: - To describe antigenic coverage in each group by assessing the HAI and SN antibody responses against a panel of H3 antigens (not present in any of the vaccine formulations). - To describe HAI and SN antibody responses in each group against each of the H3 antigens. - To compare the HAI and SN antibody responses for the groups with different H3 antigens to the control group.
This study will evaluate a home-based approach to influenza infection control, using prepositioned home-based influenza self-test kits, telemedicine services, and rapid delivery of Xofluza (Baloxavir marboxil) for administration within 48 hours of symptom onset.
The purpose of this study is to evaluate the Immunogenicity and safety of the simultaneously vaccination of Inactivated Enterovirus 71 Vaccine (EV71) and seasonal influenza vaccine(SIV)
