High-Dose Inactivated Influenza Vaccine Linked to Lower Rates of Hospitalization in HF

Patients with heart failure who receive a high-dose inactivated influenza vaccine have a decreased risk for hospitalization.

According to a study in Circulation: Heart Failure, the high-dose inactivated influenza vaccine (HD-IIV) is associated with reduced rates of hospitalizations related to laboratory-confirmed influenza, cardiorespiratory disease, cardiovascular disease, and heart failure in patients with heart failure.

The findings are based on a prespecified exploratory analysis of the DANFLU-2 trial, conducted in Denmark over three consecutive influenza seasons from 2022 to 2025.
