Cattle and human organoids reveal 2.3.4.4b H5N1 cross-species transmission potential and neuraminidase-specific neutralizing antibodies in humans
Active 2.3.4.4b H5N1 infection in cattle airway organoids suggests respiratory transmission in dairy farms. The virus also replicates in human respiratory organoids, yet pre-existing N1-specific antibodies may protect humans against H5N1 infection.
