August 22, 2013 -- With flu vaccines arriving in pharmacies and National Immunization Awareness Month well under way, the benefits of vaccines have been well documented in recent weeks. And a new study shows flu vaccines may provide even more benefits than originally thought.
The observational study looked at 559 hospital patients at the University of New South Wales and found immunization against flu cut the likelihood of heart attack by 45%. Data from the Australian study adds to epidemiological evidence linking influenza infection to cardiovascular hospitalizations, acute myocardial infarction and death. Collectively, the findings suggest healthcare systems may underestimate the health and economic benefits of vaccinating people aged 50 to 65 years old against influenza.
