"In this study, we have shown that a dissolving microneedle patch can vaccinate against influenza at least as well, and probably better than, a traditional hypodermic needle," said Mark Prausnitz, a professor in the Georgia Tech School of Chemical and Biomolecular Engineering. Just 650 microns in length and assembled into an array of 100 needles for the mouse study, the dissolving microneedles penetrate the outer layers of skin. Beyond their other advantages, the dissolving microneedles appear to provide improved immunity to influenza when compared to vaccination with hypodermic needles."In addition to this initial use for flu vaccines, this method has many compelling potential applications for other diagnostic and therapeutic pharmaceuticals.
