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.
