A skin piece that can bring vaccines cheaply and effectively has been shown off at the TED Global conference in Edinburgh. With a patch rather than a spine could alter disease prevention around the world. Prof Mark Kendall supposed the new method offered hope of practical vaccines for diseases such as malaria.
Other medical experts welcomed the news, but warned it might be inappropriate for several patients. It was fitting that Prof Kendall delivered his talk in Edinburgh where, 160 years before, Alexander Wood had lodged the first rights for the needle and syringe. The rights looked approximately alike to the needles we use today. This is a 160-year-old technology.
