NS-segment-based reporter influenza A viruses: engineering strategy, applications, and limitations

ABSTRACT Reporter-expressing recombinant influenza A viruses (IAVs) have emerged as powerful tools for studying viral infection, host–pathogen interactions, and the identification and characterization of prophylactic and/or therapeutic countermeasures for the treatment of IAV infections. By incorporating a reporter gen...

A One-Shot Multivalent Live-Attenuated Candidate Influenza Vaccine against Divergent Zoonotic H5N1 Clades

The continued emergence of genetically diverse high pathogenicity avian influenza (HPAI) H5N1 viruses with zoonotic potential highlights the urgent need for developing vaccines capable of providing broad protection against multiple circulating clades. Here, we developed a one-shot, multivalent, live-attenuated influenz...

Pre-existing and Cross-Reactive Immunity to Avian Influenza H5N1 in Humans: Implications for Pandemic Risk and Vaccine Strategies.

Current evidence on cross-reactive and cross-protective immunity to H5N1 in humans, focusing primarily on humoral immune responses is summarized, and particular attention is given to antibodies targeting conserved regions of hemagglutinin (HA) as well as neuraminidase (NA), which may provide heterosubtypic protection.

Enhanced Pathogenicity and Contact Transmissibility of Human-origin Avian Influenza H5N1 Clade 2.3.4.4b Genotype B3.13 Compared to D1.1 in Ferrets

Using the ferret model of influenza infection and transmission, it is demonstrated that the currently circulating B3.3.13 is already well adapted for mammalian infection and transmission whereas D1.1 rapidly acquires mammalian-adaptive mutations after a single infection and/or transmission event, highlighting its evolu...
