BACKGROUND: Data on influenza vaccine effectiveness (IVE) against mortality are limited, with no Australian data to guide vaccine uptake.

METHODS: Data were collected between 2010 and 2017 from a national Australian hospital-based sentinel surveillance system using a case-control design. Adults and children admitted to the 17 study hospitals with acute respiratory symptoms were tested for influenza using nucleic acid testing..View full abstract
