Aussie nanopatch offers new way to vaccinate

Researchers at Australia's University of Queensland have developed a vaccine-delivery system that dispenses with needle and syringe. The nanopatch--a small patch with thousands of vaccine-coated spikes--is designed to make the administration of vaccines simpler and more effective, according to a Reuters report, without the need for trained staff or cold-chain refrigeration. According to the report, because the skin has more immune cells than muscle, the vaccines can do their job more effectively when applied directly with a nanopatch. The device has already been proven in animal trials, and with a three-year grant from Merck ($MRK) and $100,000 from Rolex, lead biomedical engineer Mark Kendall is pushing for human clinical trials. Story
