A new medium for vaccines could remove hurdles that impede immunization campaigns in poor countries. The innovation could eliminate, for most if not all vaccines, the need to either refrigerate or rehydrate doses before use, says Bruce J. Roser of the England-based firm Cambridge Biostability.
Most current vaccines spoil unless they’re kept cold. That adds considerable expense and complexity to immunization campaigns in regions where electricity is scarce, says Bruce Weniger of the Centers for Disease Control and Prevention in Atlanta.
