Microneedle Patch for Measles Vaccination Could Be Game Changer
Centers for Disease Control and Prevention (CDC)
A new microneedle patch being developed by the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) could make it easier to vaccinate people against measles and other vaccine-preventable diseases.
The microneedle patch is designed to be administered by minimally trained workers and to simplify storage, distribution, and disposal compared with conventional vaccines.
The microneedle patch under development measures about a square centimeter and is administered with the press of a thumb. The underside of the patch is lined with 100 solid, conical microneedles made of polymer, sugar, and vaccine that are a fraction of a millimeter long. When the patch is applied, the microneedles press into the upper layers of the skin; they dissolve within a few minutes, releasing the vaccine. The patch can then be discarded.
