Uh-oh...more on the flu vaccine study from Canada

Today's Toronto Globe and Mail gives us more detail on the potential link between receiving seasonal flu vaccine and an increased risk for H1N1 infection. From the article:

Their paper (Danuta Skowronski and colleagues) found that consistency across four epidemiologic studies and one animal experiment suggested "an association that cannot be dismissed on the basis of chance and is unlikely to be explained entirely by bias." "If this association is real, these studies together suggest that recipients of seasonal [influenza vaccine] were at moderate 1.5-2-fold increased risk of medically attended H1N1 illness during the spring/summer 2009," the paper said.

Let's hope the paper is published soon. This will surely complicate vaccination campaigns.
