US scientists invent new vaccine patch

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

But the potential significance of the technique goes much further than avoiding uncomfortable jabs.

The new patches could make life-saving healthcare available for the first time for millions of people in developing countries.

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.
