Universal Flu Vaccine a Nanoparticle That Is All Stalk, No Head

Designs for universal flu vaccines try to emulate the relatively changeless parts of viral proteins, not the highly variable parts that are targeted by seasonal vaccines. The changeless parts, however, tend to be unstable. To develop a vaccine candidate that can present stabilized versions of these relatively changeless structures, scientists based at Georgia State University built double-layered protein nanoparticles. According to these scientists, their vaccine candidate can protect mice again
