Mobile Printer Produces Dissolvable COVID-19 Vaccine Patches
Scientists from MIT have developed a mobile printing device that can produce vaccine patches for COVID-19 and other diseases. The device prints 2-centimeter-wide patches that each contain hundreds of tiny needles that administer vaccine material when pressed against the skin. The patches offer major improvements over vaccine shots given in the arm, as they can be easily self-administered and are mostly painless. The printer was tested with the Pfizer and Moderna COVID-19 vaccines, but the goal of the international development team is for the device to be used for other vaccines as well.
