vaccine patch

A vaccine patch is a small, adhesive device applied to the skin that delivers vaccines through tiny needles or dissolvable particles. It allows medication to be absorbed directly through the skin, eliminating the need for injections with a syringe. Patches can be more convenient, less painful, and easier to administer, possibly enabling self-application. They also often contain molecules that help stimulate the immune system, helping the body build protection against specific diseases. This technology aims to improve vaccination experiences, increase coverage, and simplify mass immunization efforts.
