This paper develops a modified live influenza virus vaccine (RAM-IGIP) that enhances humoral and mucosal immunity against influenza, showing complete protection in mice.

This study maps the antigenic sites of H9 influenza A virus hemagglutinin using quail sera, identifying key amino acid substitutions that affect antigenic profiles and vaccine efficacy.

This study characterizes the genetic and antigenic diversity of N1 neuraminidase in IAV from North American swine over a century, identifying clades, reassortment events, and antigenic drift patterns.

The paper identifies independent evolution of H1N1 influenza A viruses in Guatemalan pigs, showing distinct amino acid signatures and genetic lineage from other Central American H1N1 pdm09 viruses.

This study shows that human-origin influenza A viruses can transmit in pigs and select for adaptive mutations in the HA gene that improve replication and fitness in swine hosts.

This study evaluates GC-376's in vivo antiviral efficacy against SARS-CoV-2 in K18-hACE2 mice, showing reduced viral loads and inflammation but no improvement in clinical symptoms or survival.
