“Scientists on Sunday unveiled lab-made human antibodies that can disable several types of influenza, including highly-lethal H5N1 bird flu and the “Spanish Flu” strain that killed tens of millions in 1918.
Tested in mice, the antibodies work by binding to a previously obscure structure in the flu virus which, when blocked, sabotages the pathogen’s ability to enter the cell it is trying to infect, according to the study.
Because this structure — described by one scientist as a “viral Achilles’ heel” — is genetically stable and has resisted mutation over time, the antibodies are effective against many different strains.
The breakthrough “holds considerable promise for further development into a medical tool to treat and prevent seasonal as well as pandemic influenza,” said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, which helped fund the study. “
