Nanoparticle flu vaccine prototype, illustration. This prototype for a universal flu vaccine consists of a nanoparticle that is a hybrid of a protein scaffold (blue) and eight influenza hemagglutinin proteins on the surface (yellow, one not visible). The hemagglutinin was specifically engineered to display antibody binding sites common to all human influenza subtypes. This nanoparticle, designed by Jeffrey Boyington, has been shown to be an effective immunogen in mice and ferrets. The 3D structure of the particle was determined by cryo-electron microscopy by researchers at the Laboratory of Infectious Diseases. This image was published in 2017.
