Hate needles? Self-administered, painless vaccine skin patch passes first human clinical trials

‘Scientists hope an experimental Band-Aid-like patch that delivers the flu vaccine could increase the number of adults who get vaccinated by providing an alternative to the conventional needle-and-syringe immunization.
On Tuesday, a team of researchers at the Georgia Institute of Technology and Emory University published a study in the Lancet, detailing the results of the first clinical trial of their flu jab patch.
The flu jab patch uses 100 water-soluble needles that are only long enough to penetrate the skin, unlike a standard flu injection that would penetrate through the skin and into the muscle.
The needles dissolve in the skin, delivering the influenza vaccine painlessly and without the need for doctor supervision. Unlike a standard flu jab, the patch can be transported and stored without refrigeration for at least one year.’
