The results showed that heart failure patients who received the flu vaccine had a 20% lower risk of death and a 15% lower risk of hospitalization during the fall and winter flu seasons than those who did not receive the flu vaccine. flu vaccine, the research team said. .
The incidence of pneumonia, which is known to be associated with heart failure, was also reduced by 40%.
