Preliminary research suggests the seasonal flu shot may put people at greater risk for getting swine flu, CBC News has learned.
“This is some evidence that has been floated. It hasn’t been validated yet, it’s very preliminary,” cautioned Dr. Don Low, microbiologist-in-chief at Mount Sinai Hospital in Toronto.
“This is obviously important data to help guide policy decisions. How can we best protect people against influenza?”
It’s important to validate the information to make sure it’s not just a fluke, and that the observation is confirmed elsewhere such as in the Southern Hemisphere, which just completed its seasonal flu season, Low added.
Four Canadian studies involved about 2,000 people, health officials told CBC News. Researchers found people who had received the seasonal flu vaccine in the past were more likely to get sick with the H1N1 virus.
