Seasonal Flu Vaccine and Swine Flu
Less then two weeks ago, Canadian researchers reported in a paper that has not been published in a journal yet that immunization with the seasonal flu vaccine increased the risk of contracting pandemic H1N1 influenza and of developing more severe complications. Although most experts pooh-poohed the findings, which are often referred to as the "Canadian problem," some provincial health authorities postponed their seasonal flu vaccination programs.
