COVID Vaccine Patch - Painless, Effective

  3D Printed Alternative to Needles                                                                 Source:  UNC-Chapel Hill New Tech That's a Breakthru for Vaccines Researchers at Stanford University and the University of North Carolina-Chapel Hill have developed a 3D printed plastic patch as an alternative to COVID-19 vaccinations by needles.  The patch contains an array of microneedles that directly deliver the vaccine into the skin.  The researchers say the microneedle patch is ten times more effective in producing an immune response than a needle and it is painless. Microneedle patches have been under development for decades.  But the breakthrough on this revolutionary new patch came from 3D printing the microneedles on a polymer patch just long enough to reach the skin and deliver the vaccine. Customization Through 3D Printing The key to the new patch is 3D printing which enables customization of the microneedles for various vaccine patches. The researchers anticipate making
