• A retrospective cohort study using routinely collected health records from patients with COVID-19 (n= 6,921) in South West England between January and July 2020 found that receiving the influenza vaccination sometime between January 1, 2019 and COVID-19 diagnosis was associated with a 15% reduced odds of all-cause mortality or hospitalization (aOR=0.85), and a 24% reduced odds of all-cause mortality alone. Differences between vaccinated and unvaccinated individuals was accounted for using a propensity score.
