A newly developed vaccination patch could signal an end to the need for painful needles injections, US researchers said on Monday.

Mark Prausnitz , a professor at the Georgia Institute of Technology and the leading researcher on the project, talked with Al Jazeera about how the patch could eventually help wipe out some fatal diseases.
