Influenza vaccine effectiveness by test-negative design–Comparison of inpatient and outpatient settings
Background Observational studies of influenza vaccine effectiveness (VE) are increasingly

but these two approaches are rarely compared directly. The aim of our study was to assess
whether influenza VE estimates differ between inpatient and outpatient settings. Methods
