Drugs developed from the newly identified antibodies could, in combination with other treatments, prevent or treat certain avian and seasonal flu strains and could also lead to the development of a long-lasting.

"We identified new human antibodies that inactivate influenza, not just bird flu, but any of the seasonal influenza viruses that affect us in the winter," said researcher Dr. Scientists May Have New Way to Fight the Flu -- A new scientific discovery could someday lead to medications to fight the flu as well as a vaccine that would not have to be changed every year because it could target a broad range of flu strains. Marasco, an associate professor of medicine at Harvard Medical School and the Dana-Farber Cancer Institute.

The antibodies recognize a new part of the influenza virus and inactivate the virus by a new mechanism, Marasco said, "so it's really a new target, new mechanism, new human antibodies." Antibodies can be used as drugs, he noted, adding that drugs derived from antibodies are commonplace in treatment for such cancers as colon, breast and lymphoma.
