Researchers Mark Prausnitz (left) of Georgia Tech and Richard Compans of Emory University are leading efforts to develop a new way to deliver the flu vaccine using microneedles.
An array of microneedles in a patch could be used to administer the flu vaccine through the skin. Image shows a prototype patch of stainless steel needles.
