SHARJAH, March 24 (Reuters)
NEW YORK (Reuters Health) – Heart failure sufferers injected with influenza vaccine are less likely to die prematurely than their counterparts who have not received the vaccine, according to a new study conducted in Denmark.
More than 134,000 patients with heart failure continued between 2003 and 2015, half of them remaining at least 3.7 years of study.
In general, at least one injection against influenza was associated with an 18% reduction in the risk of sudden death for all of its causes, particularly as a result of cardiovascular problems.
Daniel Modin, head of the study at Gentvete University Hospital and the University of Copenhagen, also found that the frequency of annual vaccinations and early vaccinations of the season was associated with an increased risk of death.
He added that influenza vaccination benefits people in general, but one study confirmed the importance of influenza vaccination in heart failure patients and also indicates that annual vaccination and continues to be important for this group of patients.
An infection such as the flu increases the body's energy demands, forces the heart to pump more blood and failing hearts may not be able to perform the task, increasing the risk of serious complications of the flu such as pneumonia.
People who do not suffer from heart failure should also be vaccinated, because not only do they help protect themselves, but they also help people whose immune system is weakened and can not be vaccinated, said the Dr. Kevin Schwartz of the Ontario Institute of Public Health.
Schwartz, who did not participate in the study by email, explained that the flu shot is needed every year for people over 6 months old.
Everyone should be vaccinated against the flu, even if they are young, healthy enough to protect themselves, and at high risk, eg younger children than those vaccinated, those with weakened immune systems and who may not respond well to the vaccine.
