Needle-Free Nanopatch Vaccine Delivery System, University of Queensland Reveals

Published: Aug 03, 2011

The needle-free nanopatch vaccine delivery system is coming soon after a consortium of investors put up $15 million for its development. The money will enable University of Queensland's Professor Mark Kendall to continue his work on the technology. It is described as the biggest breakthrough in vaccine delivery since the invention of the syringe more than 150 years ago. The nanopatch has thousands of small projections to deliver vaccines to abundant immune cells in the skin, doing away with needles plunged into muscle where there are few immune cells. Early stage testing in animals has shown a nanopatch-delivered flu vaccine is effective with only 1/150th of the dose compared to a syringe. The nanopatch is also expected to cut needle stick injuries and cross contamination.
