On-demand vaccines possible with engineered nanoparticles

Vaccines combat diseases and protect populations from outbreaks, but the life-saving technology leaves room for improvement. Vaccines usually are made en masse in centralized locations far removed from where they will be used. They are expensive to ship and keep refrigerated and they tend to have short shelf lives.

This image shows a collection of vaccinating nanoparticles, which at their largest are about 1,000 times smaller than a human hair. The inset graphic is a representation of how the engineered proteins decorate a nanoparticle’s surface.
