“TORONTO — An unpublished Canadian study that suggests getting an annual flu shot may make it easier to contract swine flu has caused most provincial governments in Canada to postpone or limit seasonal-flu vaccination programs.”

More from the article:

“It found that people who got flu shots last year were about twice as likely to contract swine flu as those who weren’t vaccinated, according to sources who have seen the study’s data.

The Public Health Agency of Canada commissioned an international panel of experts to take a look at the study’s methodology; that panel last week said it found no methodological errors and that the study has “merit,” an agency spokeswoman said.”
