A recent study published in Nature Communications by researchers at the National Institute of Allergy and Infectious Diseases (NIAID) and collaborators evaluated a replicating RNA (repRNA) vaccine designed to target a contemporary bovine-derived H5N1 virus and compared its efficacy to a vaccine based on a historical H5N1 strain used in stockpiled vaccines.
While Moderna Inc. plans to cut its expenses by $1 billion in 2025, the company has received a little breathing room by a hefty U.S. Department of Health and Human Services (HHS) grant. The Biomedical Advanced Research and Development Authority awarded Moderna roughly $590 million to support late-stage development of its mRNA-based avian-variant vaccines and to increase the number of clinical trials for another five additional subtypes of pre-pandemic influenza.
First, the good news about pandemics – and in 2024, there was big “good news.” Science Magazine named lenacapavir (Gilead Sciences Inc.) as the Breakthrough of the Year. In two separate trials, lenacapavir prevented HIV transmission with 100% efficacy in cisgender African women and 99.9% efficacy in men and gender-diverse persons when administered twice a year.
Labcorp Holdings Inc. launched its new H5N1 bird flu molecular test for humans in the U.S. as an international outbreak of the disease continues to spread in cows and poultry – and people. As BioWorld reported recently, just one mutation would make the flu variant highly transmissible in humans.
Although it does not generally infect humans, a single mutation of the H5N1 virus in the highly pathogenic avian and bovine clade 2.3.4.4b could overcome this barrier and possibly trigger a pandemic.
Although it does not generally infect humans, a single mutation of the H5N1 virus in the highly pathogenic avian and bovine clade 2.3.4.4b could overcome this barrier and possibly trigger a pandemic. Scientists at The Scripps Research Institute have warned of this possibility after studying the three-dimensional structure of the viral hemagglutinin and seeing how a change in one amino acid would make it more suitable for the human cell receptor. The researchers stress the need to monitor new mutations of this virus in order to act quickly in case the global jump to our species occurs.
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.
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.
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.
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.
