Summary

My research presents a self-administered microneedle patch made from hyaluronic acid that delivers vaccines quickly, painlessly, and effectively. Testing with a COVID-19 spike RBD antigen shows immune responses comparable to traditional injections. The patches are low-risk, easy to use, and can be stored at room temperature for a month—ideal for widespread vaccination.
