Centers for Disease Control and Prevention (CDC). Researchers at the Georgia Institute of Technology are in the process of creating a microneedle patch that could provide a simpler, safer alternative to standard measles shots. The patches are around one square centimeter in size and can be applied almost like a sticker. On the underside of each patch are one hundred conical microneedles made of polymer, sugar, and the vaccine. The microneedles are just a fraction of a millimeter long and dissolve within minutes after the patch is applied.
