AI Summary

A vaccine approach developed by researchers at the University of Nebraska–Lincoln has shown promise in protecting against highly pathogenic bird flu. The vaccine has demonstrated strong efficacy in protecting dairy calves and mice against severe disease. This development is significant in the context of avian influenza (H5N1), which has caused widespread disruption to agricultural systems globally. The virus has led to the culling of millions of commercial poultry birds in the United States since 2022, and its spread to dairy cattle in 2024 resulted in illness among farm workers with close contact to infected animals.
