Early results in line with what Australia experienced during the Southern Hemisphere’s flu season
The effectiveness of this season’s flu shot has been extremely low, with the vaccine preventing only 10 to 20 per cent of infections caused by the dominant H3N2 strain affecting Canadians, researchers have found.
The mid-season estimate for the vaccine’s ability to provide protection from this particular influenza strain is in line with what Australia experienced during the southern hemisphere’s flu season, which ended in late August as Canada’s was about to begin.
