Influenza Vaccine Effectiveness in School Outbreaks During a A(H3N2) Subclade K (J.2.4.1)-Dominated Season in Beijing, China, 2025–26
Vaccination provided protection despite intense transmission settings
Mammary and respiratory infection of sheep with H5Nx clade 2.3.4.4b viruses with milk-mediated transmission to lambs
These findings establish sheep as a viable ruminant model for H5N1 and H5N5 infection and highlight previously unidentified transmission dynamics, including milk-mediated and lamb-to-ewe spread.
Human Infection with Highly Pathogenic Avian Influenza A(H5N5) Virus
Correspondence - This report shows the importance of considering avian influenza A virus infection... even when testing for influenza virus in upper-respiratory-tract specimens is negative.
Cross-reactive human antibody responses to H5N1 influenza virus neuraminidase are shaped by immune history
Early access - Individuals likely primed in childhood with H1N1 viruses possessed higher levels of antibodies that cross-react with the NA of H5N1 viruses compared to those primed with H2N2 or H3N2 viruses.
