Human antibody may protect against all influenza A viruses

NEW YORK — Researchers have found a human antibody that may be able to protect against all influenza A viruses, according to published reports.

The antibody, FI6, could lead to the development of a universal flu vaccine because it targets groups 1 and 2, the two main groups of the influenza A virus. Previously, researchers had not been able to find an antibody that worked against both groups.

The researchers have found the antibody effective in mice and ferrets, according to the reports.
