  Abstract The emergence and broad circulation of highly pathogenic avian influenza (HPAI) H5N1 virus in wild birds and its spillover into dairy cows with sustained transmission in this species pose a major risk to felines , which are highly susceptible and often succumb to the infection . Here, we developed a novel recombinant hemagglutinin H5-based vaccine and evaluated its safety, immunogenicity, and protective efficacy against HPAI H5N1 virus in domestic cats . Immunization of cats with H5-vaccine candidate elicited robust levels of neutralizing antibodies against H5N1 virus and protection against disease, mortality, and infection upon H5N1 virus challenge. The vaccine-elicited immunity significantly reduced virus shedding and viremia , limiting systemic spread and disease severity in immunized animals. Importantly, beyond protecting susceptible felids, vaccinating cats against the H5N1 virus could also reduce the risk of human exposure - underscoring the One Health impact of i...

  A layer poultry farm (located near small rivers, ponds, and migratory birds) began showing clinical signs of an outbreak of highly pathogenic avian influenza in its hens. These signs included pale combs and wattles, followed by increased mortality. The farm owner contacted the veterinary clinic in Taji, near Baghdad. A team of veterinarians was formed, samples were taken, and sent to the central laboratory for PCR testing. Control measures were initiated, including a ban on the movement of poultry. The entire flock will be culled in accordance with the procedures stipulated in Animal Health Law No. 32 of 2013, which mandates the culling of poultry infected with highly pathogenic avian influenza.

  Abstract Monoclonal antibodies (mAbs) have become attractive tools for both the treatment and prevention of influenza A viruses due to their ability to target several viral components, which confers broad therapeutic potential. Advances in biotechnology, such as hybridoma technology , phage display technology , B cell immortalization , and artificial intelligence (Al)-driven antibody design, have significantly accelerated the development of effective mAbs. Clinical trials have shown that mAbs can improve clinical outcomes particularly in high-risk and immunocompromised populations by lowering viral loads and reducing disease severity. However, high production costs, the need for intravenous administration , and the risk of viral escape mutations are some of the obstacles to widespread clinical adoption. Post-marketing surveillance serves as a valuable source of information regarding safety, real-world effectiveness, and patterns of resistance. Broadly neutralizing antibodies (bnA...
