A vaccine made from double-layered polypeptide nanoparticles appears to protect mice against flu. The vaccine, delivered using dissolvable microneedle patches, might be adapted to treat other pathogens too.

Seasonal flu vaccines must be updated every year by predicting which strains will be the most common. Mismatched vaccines are obviously not very efficient and provide only limited protection, which increases the risk of a flu epidemic. Ideally, universal flu vaccines that are active against a broad range of influenza viruses would be better, but developing these is no easy task./.../
