Researchers at Tufts University School of Engineering have discovered a way to maintain the potency of vaccines and other drugs -- that otherwise require refrigeration -- for months and possibly years at temperatures above 110 degrees F, by stabilizing them in a silk protein made from silkworm cocoons. Importantly, the pharmaceutical-infused silk can be made in a variety of forms such as microneedles, microvesicles and films that allow the non-refrigerated drugs to be stored and administered in a single device.
