3D-Printed Patch Offers Vaccination Without a Shot
CHAPEL HILL, NC—Scientists at Stanford University and the University of North Carolina have created a 3D-printed vaccine patch that reportedly provides greater protection than a typical vaccine shot. The challenge, they say, is applying the patch directly to the skin, which is full of immune cells that vaccines target.
A study conducted in animals and published by the scientists in Proceedings of the National Academy of Sciences says the patch's immune response was 10 time greater than vaccine delivered into an arm muscle with a needle jab.
