Is this the future of vaccines? US researchers create 3D printed vaccine patches

CHAPEL HILL, North Carolina: Scientists at UNC-Chapel Hill and Stanford University said last week that they’ve successfully created a 3D-printed vaccine patch that delivers a stronger immunity response than a standard vaccine shot.

The patch, which would be placed on the skin like a Band-Aid, is covered in microneedles that deliver vaccines directly into the skin.
