A skin
patch that can deliver vaccines cheaply and effectively has been shown off at
the TEDGlobal conference in Edinburgh.
Using a
patch rather than a needle could transform disease prevention around the world,
said its inventor.
Prof Mark
Kendall said the new method offered hope of usable vaccines for diseases such
as malaria.
"Half
of vaccines in Africa are not working properly because refrigeration has failed
at some point in the chain," said Dr Kendall.
