A revolutionary skin patch that allows vaccines to be painlessly absorbed by the skin could replace conventional flu jabs within five years, scientists say.
The strip contains hundreds of microscopic pins that penetrate the outer layer of the skin and then dissolve, releasing a dose of the influenza vaccine.
Patients using the patch would be able to give themselves a flu shot without medical training – making it indispensable during a major pandemic.
It could also allow millions of people to get vaccines in developing countries where there is a shortage of medical staff.
