Researchers, led by Vancouver's Dr. Danuta Skowronski, an influenza expert at the B.C. Centre for Disease Control, noticed in the early weeks of the pandemic that people who got a flu shot for the 2008-09 winter seemed to be more likely to get infected with the pandemic virus than people who hadn't received a flu shot.
Five studies done in several provinces showed the same unsettling results. But initially research outside Canada did not, and the effect was dismissed as a "Canadian problem," a problem with the flu vaccine used in Canada.
But a new study suggests the findings were real.
But in the meantime, Skow-ronski insisted the findings should not deter people from getting flu shots.
