A Viral Achilles' Heel?

Researchers have developed antibodies that cover many strains of the influenza virus. The antibodies, targeted to vulnerable structural commonalities, might provide a more general flu vaccine to replace the current annually engineered vaccines. The antibodies target the neck of the viral infectious spike. Mount Sinai's Dr. Peter Palese referred to the approach as possibly finding "a viral Achilles' heel". There are hurdles of course, but it's exciting research.
