Immune history shapes human antibody responses to H5N1 influenza viruses

Avian H5N1 influenza viruses are circulating widely in cattle and other mammals and pose a risk for a human pandemic. Previous studies suggest that older humans are more resistant to H5N1 infections due to childhood imprinting with other group 1 viruses (H1N1 and H2N2); however, the immunological basis for this is incompletely understood. Here we measured H5N1 antibody responses in sera from 157 individuals born between 1927 and 2016. We show th…

Early Testing Complete For Bird Flu Vaccine

A bird flu vaccine for cows has passed early testing, and the mRNA injection is showing promising results. This news comes as scientists lament that there have not been any new human cases in three months. No Human Bird Flu Cases In 3 Months; Scientists Ask Why This development of this new bovine injection could mark a crucial step towards creating flu vaccines for livestock and reducing the risk of animal-to-human transmission of a virus that p…
