While the risk of contracting and dying from the H5N1 avian flu remains low for humans, researchers continue to hunt for ...

that an adjuvanted nanoparticle vaccine containing the stem region of influenza hemagglutinin can induce robust IgG responses, with the functionality of the antibodies linked to viral clearance.

Researchers in the online version of Nature Structural and Molecular Biology have identified a human antibody that disarms the flu virus by jamming the machinery it uses to fuse with host cells.

A prophylactic antibody-based immune therapy protects monkeys against severe disease caused by H5N1 avian flu, University of Pittsburgh and NIH Vaccine Research Center researchers report in Science.

This device uses a detection method based on the antigen–antibody interaction of proteins, specifically targeting hemagglutinin (HA) and nucleoprotein (NP) on the virus surface for identification.

“We found that antibody responses that were primed by ... Influenza viruses are covered with two lollipop-shaped proteins called hemagglutinin and neuraminidase, which allow the virus to attach ...
