Your Body's Universal Flu Defense

The human body makes rare antibodies effective against all flu viruses.  Boosting them might provide a better universal flu treatment.

Tests on mice suggest these immune system proteins could help most people live though a normally lethal dose of flu virus.

Reuters reports:

“The antibodies attack a part of the flu virus that all or most strains seem to have, without a lot of mutations ... when [researchers] infected mice treated with the antibodies with deadly doses of H1N1 and H5N1 flu, 60 percent to 80 percent recovered, compared to just 10 percent of untreated animals.”
