This mobile 3D printer can produce mRNA vaccine patches on the spot

A new 3D mRNA vaccine printer could mean that instead of having a healthcare professional immunise a person via a syringe and needle, people might be able to inoculate themselves using a patch with microneedles. — AFP

Scientists said last week (Apr 26, 2023) that they have developed the first mobile printer that can produce thumbnail-sized patches able to deliver mRNA (messenger ribonucleic acid) Covid vaccines.

They hope that the tabletop device will eventually help to immunise people in remote regions.
