Scientists develop first mobile printer for mRNA Covid vaccines in thumbnail-sized patches

Scientists have created the world’s first mobile printer capable of producing thumbnail-sized patches that can deliver mRNA Covid vaccines. The device prints patches containing hundreds of tiny needles which can be pressed against the skin to administer the vaccine. The microneedle patches have several advantages over traditional jabs, including painlessness, ease of self-administration, and long-term room temperature storage. While the printer is still years away from being widely available, experts have lauded the findings as an “exciting” development that could help immunize people in remote areas.
