Flu vaccine increases susceptibility to flu

In an even more unusual finding, people who were vaccinated 3 years in a row—in the 2012-13, 2013-14, and 2014-15 seasons—appeared to have a higher risk of being infected with the dominant flu strain in the latter season, according to the report, published last week in Clinical Infectious Diseases.

That surprising result echoed controversial findings reported by the Canadian flu surveillance network in the wake of the 2009 H1N1 flu pandemic. In studies published in 2010, researchers said they found that Canadians who had received a seasonal flu shot in the fall of 2008 were 1.4 to 2.5 times more likely to get an H1N1 infection requiring medical attention, compared with those who didn't get the seasonal shot.
