Scientists at Stanford University and the University of North Carolina have developed the so-called vaccine patches with a 3D printer that provide more protection than an injectable vaccine, Medical Express reveals.
Animal studies and a group of scientists have published studies that prove that the immune response to vaccine patches is ten times stronger than a needle-injected vaccine.
This method uses ultraviolet light and special resin to create patches.
"By developing this technology, we hope to lay the groundwork for a faster development of the vaccine industry that can be used more widely," said Joseph DeSimone, head of research. He pointed out that another advantage of vaccines is their simplicity. At the same time, the vaccination process will be simplified for those who are afraid of needles.
A vaccine patch is easy to use, effective, painless, less invasive than a needle since the patch is made with a 3D printer. According to the team of researchers, the design and approach they created could be adapted to vaccines against influenza, hepatitis, and COVID-19.
