Abstract
Following unprecedented disruption of influenza circulation during COVID‐19, concerns arose about postpandemic immunity debt. Community influenza epidemiological and burden data are scarce in mainland China. We estimated influenza incidence in Yancheng (2022–2025) and evaluated protection conferred by preexisting antibodies.
