Highly pathogenic avian influenza A(H5) viruses, especially those from clade 2.3.4.4b, are a growing concern as they spread among bird populations worldwide.
This research sheds light on how individuals who are seasonally exposed to these viruses may develop cross-reactive immunity, potentially influencing public health responses.
Understanding the dynamics of immunity in these individuals is crucial for managing the risks associated with avian influenza and preparing for possible future outbreaks.
