Influenza vaccination was associated with lower risk of COVID-19 diagnosis and hospitalization. Among 17,608 residents in Italy who tested for SARS-CoV-2 (28% positive), influenza vaccination (IV) was associated with lower risk of COVID-19 diagnosis (OR=0.9) in the overall cohort, and was associated with lower risk of COVID-19-related hospitalization (HR=0.7) and death (HR=0.7) in patients age ≥65 vaccinated close to the time of SARS-CoV-2 outbreak.
