Filter by:This randomized, open-label, single-site study at Saint Louis University will enroll approximately 40 subjects who are healthy, 18 to 49 years old. Subjects will be randomized in a 1:1 fashion to receive either licensed trivalent FluMist containing (2010-2011 season appropriate), or licensed inactivated trivalent influenza vaccine (2010-2011 season appropriate) so that approximately 20 subjects will be randomized to receive LAIV, and 20 will receive IIV.
This Phase 2/3 study assessed whether a single dose of seasonal trivalent inactivated split virion influenza vaccine (IVACFLU-S) is safe and well-tolerated in adults 18 to 60 years of age; and whether it will induce immune responses to each of the 3 vaccine antigens to meet 1 or both age group-specific Vietnam Ministry of Health (MOH) licensure requirements.
The purpose of the study is to investigate and compare the immune responses to influenza vaccination in monozygotic (identical) and dizygotic (fraternal) twins to determine the roles of genetics and environment in the response to flu vaccination.
This clinical study will assess the safety, tolerability and immunogenicity of VAL-506440 in healthy adult subjects.
This study will evaluate in detail the way that the immune system responds to three different kinds of flu shots that are licensed in the United States.
The objective of this study is to evaluate the safety and efficacy of concurrent administration of influenza vaccine in patients receiving anti-PD1 immunotherapy (nivolumab or pembrolizumab). This will be a prospective observational study, aiming to assess patient tolerance of treatment, adverse events (incidence, grade, need for hospitalization), incidence of influenza infections, and seroconversion rates.
This is a Phase II randomized, double-blind, placebo-controlled trial in 120 males and non-pregnant females, 18 to 49 years old, inclusive, who are in good health and meet all eligibility criteria. This clinical trial will be conducted at 3 United States sites and is designed to assess the safety, reactogenicity, and immunogenicity of two priming doses of M-001 followed by a seasonal quadrivalent inactivated influenza vaccine (IIV4). The duration of this trial for each subject will be approximately 7 months. The entire study duration will be approximately 24 months. The primary objectives are: 1) To assess the safety as measured by vaccine related adverse events, reactogenicity, and laboratory adverse events of two doses of M-001 vaccine, each dose administered approximately 21 days apart; and 2) To assess the T cell responses to M-001 component peptides following two doses of M-001.
Rationale and background: Since 2013, IB has been performing passive pharmacovigilance activities related to TIV. Objetive: To implement an active surveillance study as part of our pharmacovigilance plan while passive surveillance activities will continue. Pharmacovigilance data on TIV, via active surveillance, is being implemented in response to WHO requirements for pre-qualification of TIV. Study Design: This is a prospective cohort study. Population: Target groups for vaccination defined by The National Immunization Program of Brazil: children between six months and five years old; pregnant women; postpartum women (mothers until 45 days after birth); healthcare workers; and elderly (people over 60 years old). Study Size: A total of 900 individuals (300 health care workers, 300 elderly, 100 pregnant women, 100 post-partum women and 100 children between six months and five years old), presenting for immunization with IB TIV, and who agree to participate after providing Informed Consent. Data Analyses: Descriptive approaches will be used to meet the defined objectives described in the protocol, as well as formal statistical tests when appropriate.
This study is to compare the efficacy and safety of VIS410 in combination with oseltamivir vs oseltamivir alone in severely ill subjects with influenza A infection requiring oxygen support.
Recombinant H7 (rH7) vaccine has been shown to be poorly immunogenic in previous human clinical trials. This study will test approaches to improve the immunogenicity of H7 vaccine, namely use of a three dose regimen, use of a modified H7 HA sequence from which the Tregitope has been removed (rH7m), and inclusion of delta inulin adjuvant adjuvant in the vaccine
