Are you afraid of injections? Researchers have created a patch to replace needles
The patch, which can replace the syringe, has just passed important safety tests in the first phase of clinical trials in humans. It will allow you to painlessly apply e.g. flu vaccine.
The patch was developed by scientists in from Georgia Technological University with the support of the ln collaboration with researchers from Emory University. The research was funded by the US National Institutes of Health.
The patch is made up of hundreds of hair-like micro-needles embedded on the inside of the patch, which is where the sticky side is. Microscopic needles painlessly poke into the sk hand releasing the vaccine.
According to U.S. researchers, the use of the patch is simple enough that patients will be able to apply the flu vaccine themselves, for example. This is good news especially lnie for those who ers are afraid of the injection. According to experts in the journal „The Lancet”, The patch should increase the number of vaccinated wasps b, especially children who rych parents succumb to their complaints and objections. Although, as we know, it is not the method of administration that raises objections to the so-called “vaccine”. anti-vaccine .
Unlike the standard flu vaccination, the patch does not have to be stored in the lod ce, which means that pharmacies, but also their customers, will be able to easily b store it at home. This may prove to be a salvation for the country in the third world. The patch can be stored for one year. A vaccine administered in this way has the same properties as one administered traditionally by injection. The difference is that the patch is painless.

– If you magnify the patch under a microscope, you can see microscopically tiny needles. They penetrate easily into the sk hand – Professor Mark Prausnitz, who led the study, said. Its syndrome he first tested the effects of the patch with the flu vaccine on himself. But the clinical trial involved 100 volunteers. Asked after the tests what they would choose next time, they unanimously said that the patch.
The patch can be applied to the arm, wrist or any other part of the body. In most of the volunteers use of the patch was painless. However, some experienced side effects in the form of redness or itching. The symptoms passed after a few days.
Experts say the patch could revolutionize the way the b administration of vaccines. Although more clinical trials are needed to implement and test improvements, resulting in approval for widespread use.
The patch is also no trouble to dispose of. After use, it can be easily thrown in the trash because the micro-needles used in it dissolve. – Now we will be able to vaccinate at home, at work and even zam insert the vaccine by mail – said Dr. Nadine Rouphael of Emory University.
