that Serum in a appearance from sticky It was developed by American scientists and showed greater immune protection than the intramuscular injection method. The product, which was created via 3D printing By researchers at Stanford University and North Carolina, it has already been tested on animals.

The patch consists of 3D-printed microneedles, lined with a polymer of sufficient size to reach the skin and apply an immunizing agent.

The study, published in the Proceedings of the National Academy of Sciences, showed that the immune response to the microneedle vaccine was 50 times greater than that given under the skin, and 10 times greater than that given to the arm muscle. The results are possible because the skin is full of immune system cells that are the target audience for immunity.

In the view of Joseph M. Desimone, lead author of the study, Professor of Translational Medicine and Chemical Engineering at Stanford University and Professor Emeritus at the University of North Carolina at Chapel Hill, the new technology will lay the foundation for the development of a universal vaccine that is faster and applied painlessly and without generating anxiety.
