The new technology has undeniable advantages. As is known, an expert is required to perform the injection, which is expensive and not always possible. In addition, many people are afraid of panic attacks. Prior to this, attempts were made to create microneedles based on silicon or metal. But this was not entirely safe, because after the injections, fragments remained in the skin.
Patch-microneedles are spared from such a lack, as they completely dissolve. In tests with influenza vaccine of three types, encouraging results were obtained – all subjects had no negative reaction.
