Scientists Design 3D-printed Microneedle Vaccine Patch with Greater Immune Response

Those affected by trypanophobia could be getting an alternative. Trypanophobia is the fear or aversion to medical procedures involving injections or hypodermic needles, which can be an issue with COVID-19 vaccines presently playing a significant role. But a research team from Stanford University and the University of North Carolina at Chapel Hill may have the solution in the form of a 3D-printed vaccine patch. The patch contains 3D-printed microneedles that are long enough to reach the skin and provide vaccines. In addition, it is said to be painless, does not require cold storage, and can be self-administered. A study conducted in animals claims the immune response from the vaccine patch was 10 times greater than a vaccine with a needle jab into an arm muscle.
