Health officials are pretty sure this year’s flu vaccine is going to work just fine.
Last year’s version–was only 17-percent effective overall—and even less in people between the ages of 20 and 64.
It had a lot of trouble fighting off Influenza A—–but worked better if you happened to have Influenza B.
Last flu season——most Canadians–wound up with “A”..
THIS YEAR—the vaccine has been switched up—so its better able to fend off the flu strains that are currently making the rounds.
