Scientists create mobile printer to make covid-19 vaccine patches

Earlier this week, scientists revealed in a study the first mobile printer that can produce thumbnail-sized patches to deliver mRNA covid-19 vaccines. Scientists hope that the tabletop device will help immunise people in remote regions. The experts have called the finding "exciting.” The device prints two-centimetre-wide patches, each containing hundreds of tiny needles that administer a vaccine when pressed against the skin, according to a report.
