New research from the US published in the Pharmaceutical Journal finds that “risk of being admitted to hospital for community-acquired, influenza-associated pneumonia is lowered in people vaccinated against flu”.
The researchers found that
- Of 2,767 patients hospitalised with pneumonia, 162 (5.9%) had laboratory-confirmed influenza.
- 28 of the 162 people (17%) with influenza-pneumonia had been vaccinated.
- 766 of 2,605 controls (29%) with influenza-negative pneumonia had been vaccinated.
