flu-associated pneumonia

Further support for seasonal flu vaccination comes from a recent study that reports that patients hospitalized for flu-associated pneumonia were less likely to have received a flu vaccine.


With flu season approaching, it’s time to think about whether or not to get your annual flu shot. The results of a study published this month in the Journal of the American Medical Association may help provide another reason to do so. The study evaluated the association between vaccination against influenza and hospitalization for influenza-associated pneumonia. The study was conducted at 4 sites in the United States, between 2010 and 2012.

After accounting for various factors, such as demographics, smoking status, and the presence of other illnesses, study found that both children and adults who were hospitalized for influenza-associated pneumonia were less likely to have had a flu vaccination. Overall the study found that more than 50% of hospitalizations for influenza-associated pneumonia could be avoided by getting a flu vaccination.

The study provides further support for seasonal flu vaccination in preventing hospitalizations, especially in high-risk populations, such as the young and the elderly.
