Researchers in Georgia have developed a "microneedle patch" that can deliver the flu vaccine through a person's skin. In a new study, 70 percent of people who used the experimental patch in a Phase I clinical trial said they preferred it to a traditional flu shot.

To apply the patch, a person places it on the back of their wrist and presses down with their thumb until they hear a click. The click means that enough pressure was applied for the microneedles to enter the skin and start to dissolve.
After 20 minutes, the patch can be removed and thrown away.

Mark Prausnitz, a professor of chemical and biomedical engineering at the Georgia Institute of Technology and the senior author of the study, developed the microneedle patch with his team.
