NewsH5N1 influenza viral lineages beginning to evade human immunological defenses
A new computer modelling approach predicts the protein-antibody interactions of the potentially pandemic-causing H5N1 avian influenza virus lineage. It helps to understand the viral evolution to ensure high vaccine efficacy.

NewsCurrent antivirals likely less effective against severe infection caused by bird flu virus in cows’ milk
Scientists found that in a preclinical model, two FDA–approved flu antivirals generally did not successfully treat severe H5N1 infections. Meanwhile, the route of infection, whether through the eye, the nose or the mouth, significantly impacts effectiveness.

NewsOlder adults might be more resistant to bird flu infections than children
Previous exposures to seasonal flu strains could prime the immune system to produce antibodies against the current version of H5N1 avian influenza virus in older adults, whilst children would benefit more from H5N1 vaccinations.

NewsImmunity against seasonal H1N1 flu reduces bird flu severity in ferrets, study suggests
Pre-existing immunity against seasonal H1N1 flu might help explain why most reported human cases of H5N1 bird flu in the U.S. have not resulted in lethal outcomes, suggests a new study.

NewsRaw milk is risky, but airborne transmission of H5N1 from cow’s milk is inefficient in mammals
New research suggests that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.
