The efficacy of seasonal flu vaccines varies due to the ability of the influenza virus to mutate rapidly. The achievement of a universal flu vaccine conferring protection against all strains, including those with pandemic potential, for longer than a single season would provide a great benefit and has not yet been achieved.
Researchers have identified a gene associated with whether patients hospitalized with respiratory viral infections recover rapidly or face life-threatening complications. The gene has the potential to be used as a diagnostic tool or biomarker, which could help triage patients suffering from severe respiratory infections. Having such a biomarker would help clinicians in their early risk assessments to manage their intervention strategies.
“There are hundreds of strains of bird flu, and most of them don’t infect humans, or even mammals,” Stephen Cusack told BioWorld. “There are two main reasons for that.” To be able to cause an infection, a virus “has to be able to get into the cell, and for that it needs a receptor,” Cusack said. For influenza viruses, those receptors are hemagglutinin receptors, and they differ in subtle but important ways between birds and mammals.
Arcturus Therapeutics Holdings Inc. has announced its pandemic influenza vaccine is on track to enter a phase I clinical trial in Q4 of 2024. The vaccine, ARCT-2304, utilizes Arcturus’ STARR self-amplifying mRNA and LUNAR delivery platform technologies to deliver antigens designed to elicit a protective response against the H5N1 strain of avian influenza.
Armed with $55 million in series A funds and a U.S. government contract, Cambridge, Mass.-based Red Queen Therapeutics Inc. launched operations this week, with plans to advance its novel stapled lipopeptide platform, which creates new antiviral therapies that do not rely on the immune system to work.
Vir Biotechnology Inc.’s focus will look a little different for the latter half of 2024, as the San Francisco-based firm disclosed a restructuring that will cut about a fourth of its workforce and phase out programs targeting influenza and COVID-19 as well as vaccines developed using its T-cell-based viral vector platform.
With the COVID-19 pandemic still visible in the rearview mirror, the World Health Organization (WHO) is taking no chances as it preps for human avian influenza, or H5N1, a subtype of influenza A.
Researchers from CONICET and affiliated organizations presented the discovery of novel llama-derived single-chain antibody fragments (VHHs) specific for type A influenza virus.
Researchers from Children’s Hospital Boston and affiliated organizations have reported the discovery and preclinical characterization of a novel TLR7/8 agonist adjuvant for vaccination, PVP-037.
Curevac AG is casting off the deadweight of its pandemic push to translate its mRNA technology into a marketed COVID-19 vaccine, in a new €1.45 billion (US$1.6 billion) deal in which GSK plc will acquire full rights to infectious disease vaccines the two were co-developing.
