Scientists develop mobile printer for mRNA Covid vaccine patches


Scientists said Monday they have developed the first mobile printer that can produce thumbnail-sized patches able to deliver mRNA Covid vaccines, hoping the tabletop device will help immunise people in remote regions. While many hurdles remain and the 3D printer is likely years away from becoming available, experts hailed the “exciting” finding The device prints two-centimetre-wide patches which each contain hundreds of tiny needles that administer a vaccine when pressed against the skin.

These “microneedle patches” offer a range of advantages over traditional jabs in the arm, including that they can be self-administered, are painless, could be more palatable to the vaccine-hesitant and can be stored at room temperature for long periods of time.
