Excerpt: Dr. Danuta Skowronski, a flu expert at the B.C. Centre for Disease Control in Vancouver, spotted a surprising and unsettling trend when she looked at data on people in British Columbia who contracted H1N1 in the spring and summer of 2009. People who had received a seasonal flu shot the previous autumn were more likely to contract the new pandemic strain.
Excerpt: Vincent’s study raises a red flag. She and her colleagues immunized piglets with an H1N2 vaccine, then exposed them to the H1N1 virus that caused the 2009 pandemic. Though both viruses were H1s, they were quite different genetically.Instead of being protected, the H1N2-vaccinated pigs developed more severe disease than exposed pigs that hadn’t been pre-vaccinated. When the researchers tested the blood of the vaccinated pigs, they found high levels of antibodies that attached to the stalk of the H1N1 hemagglutinin, but not to the head of the protein.
