Researchers at the La Jolla Institute for Allergy & Immunology and colleagues have found that previous influenza infections may provide at least some level of immunity to the H1N1 "swine" flu."
The question we asked was, 'Is the swine flu more like the seasonal flu or like a totally new strain of influenza where there would be no immunity?'," said Alessandro Sette, Ph.D., an internationally recognized vaccine expert and director of the La Jolla Institute's Center for Infectious Disease. "What we have found is that the swine flu has similarities to the seasonal flu, which appear to provide some level of pre-existing immunity. This suggests that it could make the disease less severe in the general population than originally feared."
