Vaccine stabilization technique proves as smooth as silk
Vaccines and other biologic drugs quickly degenerate and lose their effectiveness if left out of the fridge for very long, creating a huge problem for healthcare delivery in less developed parts of the world. Fortunately, a new preservation technique could offer longer shelf lives. Reporting today in the Proceedings of the National Academy of Sciences (PNAS), researchers have discovered a silk protein capable of stabilizing heat-sensitive biologics for months at a time at room temperatures or even hotter.
