Researchers at the 2012 Interscience Conference on Antimicrobial Agents and Chemotherapy presented the results of a study in which they studied the interaction between seasonal and pandemic viruses in ferrets vaccinated with a seasonal flu virus and subsequently infected with the pandemic H1N1 virus. All the vaccinated ferrets became ill with the H1N1 virus and exhibited more severe clinical signs of illness than unvaccinated ferrets. The researchers concluded that the seasonal vaccine worsened the symptoms of the pandemic flu.
