U.S. health officials are considering using vaccines in poultry to stem an ongoing outbreak of bird flu.
Scientists will begin testing the first vaccines for birds in years as the spread of avian influenza has killed about 58 million birds, according to the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service.
While the outbreak has devastated both wild and commercial bird flocks, many of the dead animals are commercially raised poultry.
Nearly every state – 47 of 50 – has spotted the virus in poultry, and all have found it spreading in wild birds.
