High-dose vs standard-dose influenza vaccine and cardiovascular outcomes in older adults

About The Study: This study found reduced incidence of cardiorespiratory hospitalization among those who received high-dose inactivated influenza vaccine vs standard-dose inactivated influenza vaccine, driven by a lower incidence of cardiovascular hospitalizations, and particularly heart failure hospitalizations. These differences should be interpreted as exploratory findings in the setting of a large randomized clinical trial with a neutral primary outcome.
