American poultry and cattle farmers are seeking permission to vaccinate their livestock against a highly pathogenic strain of bird flu, as they face significant losses with the largest outbreak of the disease since 2022, resulting in the death of over 100 million chickens and turkeys. The US Department of Agriculture is developing the necessary vaccines but is cautious due to potential export restrictions. The concern extends to dairy farms, with a new strain of bird flu detected that can affect mammals, posing a risk to flocks worth $67 billion. This strain has been identified in dairy cows, sheep, and farm workers, prompting the allocation of five million dollars for vaccinating farm workers against seasonal flu. This situation highlights the urgent need for a solution to protect livestock from bird flu, with similar challenges being faced in Russia.
