MOH (Minister of Health) cautious on flu shot fears
Unpublished Canadian data are raising concerns about whether it's a good idea to get a seasonal flu shot this season.
Drawn from a series of studies from British Columbia, Quebec and Ontario, the data appear to suggest that people who got a seasonal flu shot last year are about twice as likely to catch swine flu as people who didn't.
Concern about the unconfirmed findings is playing into calls from Quebec and possibly other jurisdictions to delay or even cancel this year's seasonal flu shot campaigns across the country...
...The findings are causing consternation abroad as well, with officials at public health agencies and even at the World Health Organization worried the alleged link will deter people from getting vaccinated in a fall when many people are being asked to get both seasonal and pandemic flu shots.
The Public Health Agency of Canada knows of the findings and has been seeking help here and internationally to try to figure out if the effect is real or if the studies are flawed.
